112-558: The first news about the existence of the New Siberian Islands was brought by a Cossack , Yakov Permyakov , in the beginning of the 18th century. In 1712, a Cossack unit led by M. Vagin reached the Great Lyakhovsky Island . In 1809–10 Yakov Sannikov and Matvei Gedenschtrom went to the New Siberian Islands on a cartographic expedition. Sannikov reported the sighting of a "new land" north of Kotelny in 1811. This became

224-470: A thin section using a method like the Gazzi-Dickinson Method . This yields the relative percentages of quartz, feldspar, and lithic grains and the amount of clay matrix. The composition of a sandstone can provide important information on the genesis of the sediments when used with a triangular Q uartz, F eldspar, L ithic fragment ( QFL diagrams ). However, geologist have not been able to agree on

336-583: A Cossack near Kiliya . In the 16th century, these Cossack societies merged into two independent territorial organizations, as well as other smaller, still-detached groups: There are also references to the less well-known Tatar Cossacks, including the Nağaybäklär and Meshchera -speaking Volga Finns , of whom Sary Azman was the first Don ataman . These groups were assimilated by the Don Cossacks, but had their own irregular Bashkir and Meshchera Host up to

448-499: A combined Muscovite-Swedish army and facilitate the occupation of Moscow from 1610 to 1611, riding into Moscow with Stanisław Żółkiewski . The final attempt by King Sigismund and Wladyslav to seize the throne of Muscovy was launched on April 6, 1617. Although Wladyslav was the nominal leader, it was Jan Karol Chodkiewicz who commanded the Commonwealth forces. By October, the towns of Dorogobuzh and Vyazma had surrendered. But

560-696: A defeat, when the counterattack on Moscow by Chodkiewicz failed between Vyasma and Mozhaysk , prompted the Polish-Lithuanian army to retreat. In 1618, Petro Konashevych-Sahaidachny continued his campaign against the Tsardom of Russia on behalf of the Cossacks and the Polish-Lithuanian Commonwealth. Numerous Russian towns were sacked, including Livny and Yelets . In September 1618, with Chodkiewicz, Konashevych-Sahaidachny laid siege to Moscow, but peace

672-829: A folded and faulted assemblage of Precambrian metamorphic rocks ; upper Paleozoic to Triassic sandstones and shales ; Jurassic to lower Cretaceous turbidites ; Cretaceous granites ; and ophiolites . The Anzhu Islands consist of a highly faulted and folded assemblage of Ordovician to Devonian limestones , dolomites , sandstones, shales, volcanoclastic strata, and igneous rocks; upper Paleozoic to Triassic sandstones and shales; Jurassic to lower Cretaceous turbidites; and upper Cretaceous to Pliocene sandstones and shales. The De Long Islands consist of early Paleozoic, middle Paleozoic, Cretaceous, and Neogene sedimentary and igneous (mostly basalt ) rocks. These sedimentary, metamorphic, and igneous rocks are mantled by loose Pleistocene and Holocene sediments that range in thickness from

784-456: A fraction of a meter to about 35 meters (115 feet). Digby also noted that some early papers published about the New Siberian Islands incorrectly describe them, often along with other Arctic islands (e.g. Wrangel Island ), as being made either up almost entirely of mammoth bones and tusks or of ice, sand, and the bones of mammoths and other extinct megafauna. Some of these papers were written by persons (e.g. D. Gath Whitley) who had never visited

896-652: A lifestyle that combined the ancient Cossack order and habits with those of the Knights Hospitaller . The Cossack structure arose, in part, in response to the struggle against Tatar raids. Socio-economic developments in the Polish-Lithuanian Commonwealth were another important factor in the growth of the Ukrainian Cossacks. During the 16th century, serfdom was imposed because of the favorable conditions for grain sales in Western Europe. This subsequently decreased

1008-428: A period of some 200,000 years. Radiocarbon dates obtained from the collagen of 87 mammoth tusks and bones collected from Faddeevsky , Kotelniy , and New Siberia islands ranged from 9470±40  BP to greater than 50,000 BP (C). The entire archipelago has been designated an Important Bird Area (IBA) by BirdLife International because it supports breeding populations of many species of birds. The climate

1120-612: A prisoner of the Solovetsky Islands . Some Cossacks moved to the Danube Delta region, where they established a new sich under Ottoman rule. To prevent further defection of Cossacks, the Russian government restored the special Cossack status of the majority of Zaporozhian Cossacks. This allowed them to unite in the Host of Loyal Zaporozhians, and later to reorganize into other hosts, of which

1232-649: A reputation for their raids against the Ottoman Empire and its vassals , although they also sometimes plundered other neighbors. Their actions increased tension along the southern border of the Polish–Lithuanian Commonwealth. Low-level warfare took place in those territories for most of the period of the Commonwealth (1569–1795). Prior to the formation of the Zaporozhian Sich , Cossacks had usually been organized by Ruthenian boyars , or princes of

1344-478: A sandstone goes through as the degree of kinetic processing of the sediments increases. Dott's (1964) sandstone classification scheme is one of many such schemes used by geologists for classifying sandstones. Dott's scheme is a modification of Gilbert's classification of silicate sandstones, and it incorporates R.L. Folk's dual textural and compositional maturity concepts into one classification system. The philosophy behind combining Gilbert's and R. L. Folk's schemes

1456-459: A set of boundaries separating regions of the QFL triangle. Visual aids are diagrams that allow geologists to interpret different characteristics of a sandstone. For example, a QFL chart can be marked with a provenance model that shows the likely tectonic origin of sandstones with various compositions of framework grains. Likewise, the stage of textural maturity chart illustrates the different stages that

1568-445: A twofold classification: Cement is what binds the siliciclastic framework grains together. Cement is a secondary mineral that forms after deposition and during burial of the sandstone. These cementing materials may be either silicate minerals or non-silicate minerals, such as calcite. Sandstone that becomes depleted of its cement binder through weathering gradually becomes friable and unstable. This process can be somewhat reversed by

1680-426: Is arctic and severe. Snow cover is present for 9 months of the year. Permafrost and underground ice are very common. The surface of the islands is covered with Arctic tundra vegetation and numerous lakes. The ocean surrounding the islands is covered with ice most of the year. During warm years, the ocean briefly opens for navigation July through October. During cold years, islands may remain ice-locked through

1792-837: Is a distinction that can be recognized in the field . In turn, the distinction between an orthoquartzite and a metaquartzite is the onset of recrystallization of existing grains. The dividing line may be placed at the point where strained quartz grains begin to be replaced by new, unstrained, small quartz grains, producing a mortar texture that can be identified in thin sections under a polarizing microscope. With increasing grade of metamorphism, further recrystallization produces foam texture , characterized by polygonal grains meeting at triple junctions, and then porphyroblastic texture , characterized by coarse, irregular grains, including some larger grains ( porphyroblasts .) Sandstone has been used since prehistoric times for construction, decorative art works and tools. It has been widely employed around

1904-523: Is likely formed during eogenesis. Deeper burial is accompanied by mesogenesis , during which most of the compaction and lithification takes place. Compaction takes place as the sand comes under increasing pressure from overlying sediments. Sediment grains move into more compact arrangements, ductile grains (such as mica grains) are deformed, and pore space is reduced. In addition to this physical compaction, chemical compaction may take place via pressure solution . Points of contact between grains are under

2016-431: Is redeposited in the unstrained pore spaces. Mechanical compaction takes place primarily at depths less than 1,000 meters (3,300 ft). Chemical compaction continues to depths of 2,000 meters (6,600 ft), and most cementation takes place at depths of 2,000–5,000 meters (6,600–16,400 ft). Unroofing of buried sandstone is accompanied by telogenesis , the third and final stage of diagenesis. As erosion reduces

2128-443: Is that it is better able to "portray the continuous nature of textural variation from mudstone to arenite and from stable to unstable grain composition". Dott's classification scheme is based on the mineralogy of framework grains, and on the type of matrix present in between the framework grains. In this specific classification scheme, Dott has set the boundary between arenite and wackes at 15% matrix. In addition, Dott also breaks up

2240-669: The Black Sea Cossack Host together with Loyal Zaporozhians. Most of the remaining Cossacks who had stayed in the Danube Delta returned to Russia in 1828. They settled in the area north of the Azov Sea , becoming known as the Azov Cossacks . The majority of Zaporizhian Cossacks who had remained loyal to Russia despite the destruction of Sich became known as Black Sea Cossacks . Both Azov and Black Sea Cossacks were resettled to colonize

2352-667: The Black Sea Host was most important. Because of land scarcity resulting from the distribution of Zaporozhian Sich lands among landlords, they eventually moved on to the Kuban region . The majority of Danubian Sich Cossacks moved first to the Azov region in 1828, and later joined other former Zaporozhian Cossacks in the Kuban region. Groups were generally identified by faith rather than language in that period, and most descendants of Zaporozhian Cossacks in

2464-649: The Cossack szlachta . The uprising was one of a series of catastrophic events for the Commonwealth, known as The Deluge , which greatly weakened the Polish-Lithuanian Commonwealth and set the stage for its disintegration 100 years later. Influential relatives of the Ruthenian and Lithuanian szlachta in Moscow helped to create the Russian–Polish alliance against Khmelnitsky's Cossacks, portrayed as rebels against order and against

2576-727: The Danubian Sich . While Ukrainian folklore remembers the Danubian Sich, other new siches of Loyal Zaporozhians on the Bug and Dniester rivers did not achieve such fame. Other Cossacks settled on the Tisa river in the Austrian Empire , also forming a new Sich. During the Cossack sojourn under Turkish rule, a new host was founded that numbered around 12,000 people by the end of 1778. Cossack settlement on

The Cossack way of life persisted via both direct descendants and acquired ideals in other nations into the twentieth century, though the sweeping societal changes of the Russian Revolution disrupted Cossack society as much as any other part of Russia; many Cossacks migrated to other parts of Europe following

2800-702: The Dnieper Rapids (Ukrainian: za porohamy ), also known as the Wild Fields . The group became well known, and its numbers increased greatly between the 15th and 17th centuries. The Zaporozhian Cossacks played an important role in European geopolitics , participating in a series of conflicts and alliances with the Polish–Lithuanian Commonwealth , Russia , and the Ottoman Empire . The Zaporozhians gained

2912-682: The Dniester and the Volga were mentioned in Ruthenian chronicles. Historical records of the Cossacks before the 16th century are scant, as is the history of the Ukrainian lands in that period. As early as the 15th century, a few individuals ventured into the Wild Fields , the southern frontier regions of Ukraine separating Poland-Lithuania from the Crimean Khanate. These were short-term expeditions, to acquire

3024-808: The Don and the Dnieper after the demise of the Khazars . Their arrival was probably not before the 13th century, when the Mongols broke the power of the Cumans , who had assimilated the previous population on that territory. It is known that new settlers inherited a lifestyle that long pre-dated their presence, including that of the Turkic Cumans and the Circassian Kassaks. In contrast, Slavic settlements in southern Ukraine started to appear relatively early during Cuman rule, with

3136-826: The Don Republic and the Kuban People's Republic , and the revived Hetmanate emerged in Ukraine. Cossack troops formed the effective core of the anti-Bolshevik White Army , and Cossack republics became centers for the anti-Bolshevik White movement . With the victory of the Red Army , Cossack lands were subjected to decossackization and the Holodomor famine. As a result, during the Second World War, their loyalties were divided and both sides had Cossacks fighting in their ranks. Following

3248-647: The Khmelnytsky Uprising . Afterwards, the Treaty of Pereyaslav (1654) brought most of the Cossack state under Russian rule. The Sich, with its lands, became an autonomous region under the Russian protectorate. The Don Cossack Army, an autonomous military state formation of the Don Cossacks under the citizenship of the Moscow State in the Don region in 1671–1786, began a systematic conquest and colonization of lands to secure

3360-587: The Kuban steppe , a crucial foothold for Russian expansion in the Caucasus . In 1860, more Cossacks were resettled to the North Caucasus , and merged into the Kuban Cossack Host . The native land of the Cossacks is defined by a line of Russian town-fortresses located on the border with the steppe, and stretching from the middle Volga to Ryazan and Tula , then breaking abruptly to the south and extending to

These islands represent the remains of about 1.6 million square kilometers of the formerly subaerial Great Arctic Plain that now lies submerged below parts of the Arctic Ocean , East Siberian Sea , and Laptev Sea . At this plain's greatest extent, sea level was 100–120 m below modern sea-level and the coastline lay 700 to 1000 kilometers north of its current position. This plain did not undergo extensive glaciation during

3584-573: The Polish–Ottoman War of 1633–1634. Cossack numbers increased when the warriors were joined by peasants escaping serfdom in Russia and dependence in the Commonwealth. Attempts by the szlachta to turn the Zaporozhian Cossacks into peasants eroded the formerly strong Cossack loyalty towards the Commonwealth. The government constantly rebuffed Cossack ambitions for recognition as equal to

By the end of the 15th century, the term was also applied to peasants who had fled to the devastated regions along the Dnieper and Don Rivers , where they established their self-governing communities. Until at least the 1630s, these Cossack groups remained ethnically and religiously open to virtually anybody, although

3808-733: The Roman Catholic -dominated Commonwealth. Tensions increased when Commonwealth policies turned from relative tolerance to suppression of the Eastern Orthodox Church after the Union of Brest . The Cossacks became strongly anti-Roman Catholic, an attitude that became synonymous with anti-Polish. After the Ottoman-Polish and Polish-Muscovite warfare ceased, the official Cossack register was again reduced. The registered Cossacks ( reiestrovi kozaky ) were isolated from those who were excluded from

3920-586: The Russian Navy re-established a Soviet era naval base on Kotelny Island which had lain abandoned since 1993.

In the 2002 Russian Census , 140,028 people reported their ethnicity as Cossack. There are Cossack organizations in Russia, Kazakhstan , Ukraine , Belarus , and the United States . The Zaporozhian Cossacks lived on the Pontic–Caspian steppe below

The principal political problem of the hetmans who followed the Pereyeslav Agreement was defending the autonomy of the Hetmanate from Russian/Muscovite centralism. The hetmans Ivan Vyhovsky , Petro Doroshenko and Ivan Mazepa attempted to resolve this by separating Ukraine from Russia. Relations between

4256-556: The szlachta . Plans for transforming the Polish–Lithuanian two-nation Commonwealth into a Polish–Lithuanian–Ruthenian Commonwealth made little progress, due to the unpopularity among the Ruthenian szlachta of the idea of Ruthenian Cossacks being equal to them and their elite becoming members of the szlachta . The Cossacks' strong historic allegiance to the Eastern Orthodox Church also put them at odds with officials of

4368-550: The 16th century, with the area of the Polish-Lithuanian Commonwealth extending south, the Zaporozhian Cossacks were mostly, if tentatively, regarded by the Commonwealth as their subjects. Foreign and internal pressure on the Polish-Lithuanian Commonwealth led to the government making concessions to the Zaporozhian Cossacks. King Stephen Báthory granted them certain rights and freedoms in 1578, and they gradually began to create their foreign policy. They did so independently of

4704-413: The Cossack starshyna , including hetman Ivan Vyhovsky . The treaty failed, however, because the starshyna were divided on the issue, and it had even less support among rank-and-file Cossacks. As a result of the mid–17th century Khmelnytsky Uprising, the Zaporozhian Cossacks briefly established an independent state, which later became the autonomous Cossack Hetmanate (1649–1764). It was placed under

4816-593: The Cossack nation of the Zaporozhian Host was divided into two autonomous republics of the Russian Tsardom: the Cossack Hetmanate , and the more independent Zaporizhia . These organisations gradually lost their autonomy, and were abolished by Catherine II in the late 18th century. The Hetmanate became the governorship of Little Russia , and Zaporizhia was absorbed into New Russia . With the destruction of

The Empire responded with executions and tortures, the destruction of the western part of the Don Cossack Host during the Bulavin Rebellion in 1707–1708, the destruction of Baturyn after Mazepa's rebellion in 1708, and the formal dissolution of the Lower Dnieper Zaporozhian Host after Pugachev's Rebellion in 1775. After

5152-448: The Hetmanate and their new sovereign began to deteriorate after the autumn of 1656, when the Muscovites, going against the wishes of their Cossack partners, signed an armistice with the Polish-Lithuanian Commonwealth in Vilnius . The Cossacks considered the Vilnius agreement a breach of the contract they had entered into at Pereiaslav. For the Muscovite tsar, the Pereiaslav Agreement signified the unconditional submission of his new subjects;

The predominant view of ethnologists and historians is that its origins lie in the common culture dating back to the Black Sea Cossacks. The waning loyalty of the Cossacks, and the szlachta 's arrogance towards them, resulted in several Cossack uprisings against

During the frigid polar climate of the Last Glacial Maximum, 17,000 to 24,000 BC, small passive ice caps formed on the adjacent De Long Islands . Fragments of these ice caps remain on Jeannette , Henrietta , and Bennett Islands . Traces of former small slope and cirque glaciers in

Such statements have been shown to be fictional in nature by detailed studies of the geology of the New Siberian Islands by professional geologists, paleontologists, and other scientists. As noted by Baron Eduard V. Toll in his account of

The ivory, along with mammoth and other bones, are found in recent beaches, drainage areas, river terraces and river beds. The New Siberian Islands are unique in the burial and preservation of fossil ivory "in such a wonderful state of preservation that the tusks so found cannot be distinguished from

5712-445: The Ottomans, to ease pressure on their own borders. Many Cossacks and Tatars developed longstanding enmity due to the losses of their raids. The ensuing chaos and cycles of retaliation often turned the entire southeastern Polish–Lithuanian Commonwealth border into a low-intensity war zone. It catalyzed escalation of Commonwealth–Ottoman warfare, from the Moldavian Magnate Wars (1593–1617) to the Battle of Cecora (1620) , and campaigns in

5824-464: The Perestroika era in the late 1980s, descendants of Cossacks began to revive their national traditions. In 1988, the Soviet Union enacted a law permitting the re-establishment of former Cossack hosts and the formation of new ones. Throughout the 1990s, numerous regional authorities consented to delegate certain local administrative and policing responsibilities to these reconstituted Cossack hosts. Between 3.5 and 5 million people associate themselves with

5936-435: The Polish government. Cossack rebellions eventually culminated in the Khmelnytsky Uprising , led by the hetman of the Zaporizhian Sich, Bohdan Khmelnytsky . The Zaporozhian Sich had its own authorities, its own "Lower" Zaporozhian Host , and its own land. In 1775, the Lower Dnieper Zaporozhian Host was destroyed. Later, its high-ranking Cossack leaders were exiled to Siberia, its last chief, Petro Kalnyshevsky , becoming

The Union of Hadiach provoked a war between the Cossacks and the Muscovites/Russians that began in the fall of 1658. In June 1659, the two armies met near the town of Konotop . One army comprised Cossacks, Tatars, and Poles, and the other was led by a top Muscovite military commander of

6160-537: The Polish–Lithuanian Commonwealth and the Lower Dnieper (Nyzovyi in Ukrainian) Cossack Host under the joint protectorate of Russia and the Commonwealth. By the end of the 18th century, Cossack nations had been transformed into a special military estate ( sosloviye ), "a military class". The Malorussian Cossacks (the former Registered Cossacks also known as "Town Zaporozhian Host") were excluded from this transformation, but were promoted to membership of various civil estates or classes (often Russian nobility), including

6272-402: The Polish–Lithuanian Commonwealth in the early 17th century. Finally, the King's adamant refusal to accede to the demand to expand the Cossack Registry prompted the largest and most successful of these: the Khmelnytsky Uprising , that began in 1648. Some Cossacks, including the Polish szlachta in Ukraine, converted to Eastern Orthodoxy, divided the lands of the Ruthenian szlachta , and became

6384-582: The Pugachev rebellion, the Empire renamed the Yaik Host, its capital, the Yaik Cossacks, and the Cossack town of Zimoveyskaya in the Don region to try to encourage the Cossacks to forget the men and their uprisings. It also formally dissolved the Lower Dnieper Zaporozhian Cossack Host, and destroyed their fortress on the Dnieper (the Sich itself). This may in part have been due to the participation of some Zaporozhian and other Ukrainian exiles in Pugachev's rebellion. During his campaign, Pugachev issued manifestos calling for restoration of all borders and freedoms of both

6496-478: The Russian border was approved by the Ottoman Empire after the Cossacks officially vowed to serve the sultan . Yet internal conflict, and the political manoeuvring of the Russian Empire led to splits among the Cossacks. Some of the runaway Cossacks returned to Russia, where the Russian army used them to form new military bodies that also incorporated Greeks, Albanians and Crimean Tatars. After the Russo-Turkish war of 1787–1792 , most of these Cossacks were absorbed into

6608-434: The Russian navy had no Cossack ships and units. Cossack service was considered rigorous. Cossack forces played an important role in Russia's wars of the 18th–20th centuries, including the Great Northern War , the Seven Years' War , the Crimean War , the Napoleonic Wars , the Caucasus War , many Russo-Persian Wars , many Russo-Turkish Wars , and the First World War . In the late 19th and early 20th centuries,

The last, ultimately unsuccessful, attempt to rebuild the Polish–Cossack alliance and create a Polish–Lithuanian–Ruthenian Commonwealth was the 1658 Treaty of Hadiach . The treaty was approved by the Polish king and the Sejm , and by some of

There were several major Cossack hosts in the 16th century: near the Dnieper, Don, Volga and Ural Rivers ; the Greben Cossacks in Caucasia ; and the Zaporozhian Cossacks , mainly west of the Dnieper. It is unclear when people other than the Brodnici and Berladnici (which had a Romanian origin with large Slavic influences) began to settle in the lower reaches of major rivers such as

6944-409: The Tatars and Turks. Tsar Boris Godunov had incurred the hatred of Ukrainian Cossacks by ordering the Don Cossacks to drive away from the Don all the Ukrainian Cossacks fleeing the failed uprisings of the 1590s. This contributed to the Ukrainian Cossacks' willingness to fight against him. In 1604, 2,000 Zaporizhian Cossacks fought on the side of the Polish-Lithuanian Commonwealth and their proposal for

Two thirds of these "cossacks", however, were in fact Ukrainian civilians, only 500 being professional Ukrainian Cossacks. On July 4, 1610, 4,000 Ukrainian Cossacks fought in the Battle of Klushino , on the side of the Polish-Lithuanian Commonwealth. They helped to defeat

7168-418: The Tsarist regime used Cossacks extensively to perform police service. Cossacks also served as border guards on national and internal ethnic borders, as had been the case in the Caucasus War. During the Russian Civil War , Don and Kuban Cossacks were the first people to declare open war against the Bolsheviks . In 1918, Russian Cossacks declared their complete independence, creating two independent states,

7280-409: The Ukrainian hetman considered it a conditional contract from which one party could withdraw if the other was not upholding its end of the bargain. The Ukrainian hetman Ivan Vyhovsky, who succeeded Khmelnytsky in 1657, believed the Tsar was not living up to his responsibility. Accordingly, he concluded a treaty with representatives of the Polish king, who agreed to re-admit Cossack Ukraine by reforming

Together with Cossacks of Greater Russian origin , as well as the vast majority of Old Believers and other people from "Greater Russia" ( Muscovy ), they settled in the area of the Danube river, and founded a new Sich. Many Ukrainian peasants and adventurers later joined

Pore space includes the open spaces within a rock or a soil. The pore space in a rock has a direct relationship to the porosity and permeability of the rock. The porosity and permeability are directly influenced by the way the sand grains are packed together. Sandstones are typically classified by point-counting

7616-660: The borders on the Volga , the whole of Siberia (see Yermak Timofeyevich ), and the Yaik (Ural) and Terek Rivers . Cossack communities had developed along the latter two rivers well before the arrival of the Don Cossacks. By the 18th century, Cossack hosts in the Russian Empire occupied effective buffer zones on its borders. The expansionist ambitions of the Empire relied on ensuring Cossack loyalty, which caused tension given their traditional exercise of freedom, democracy, self-rule, and independence. Cossacks such as Stenka Razin , Kondraty Bulavin , Ivan Mazepa and Yemelyan Pugachev led major anti-imperial wars and revolutions in

Historian Gary Dean Peterson writes: "With all this unrest, Ivan Mazepa of the Ukrainian Cossacks was looking for an opportunity to secure independence from Russia and Poland". In response to Mazepa's alliance with Charles XII of Sweden , Peter I ordered

8064-407: The depth of burial, renewed exposure to meteoric water produces additional changes to the sandstone, such as dissolution of some of the cement to produce secondary porosity . Framework grains are sand-sized (0.0625-to-2-millimeter (0.00246 to 0.07874 in) diameter) detrital fragments that make up the bulk of a sandstone. Most framework grains are composed of quartz or feldspar , which are

8176-456: The development of the Cossacks. In the 15th century, Cossack society was described as a loose federation of independent communities, which often formed local armies and were entirely independent from neighboring states such as Poland, the Grand Duchy of Moscow, and the Crimean Khanate. According to Mykhailo Hrushevsky , the first mention of Cossacks dates back to the 14th century, although

8288-446: The different types of framework grains that can be present in a sandstone into three major categories: quartz, feldspar, and lithic grains. When sandstone is subjected to the great heat and pressure associated with regional metamorphism , the individual quartz grains recrystallize, along with the former cementing material, to form the metamorphic rock called quartzite . Most or all of the original texture and sedimentary structures of

8400-482: The earliest, such as Oleshky , dating back to the 11th century. Early "Proto-Cossack" groups are generally reported to have come into existence within what is now Ukraine in the 13th century as the influence of Cumans grew weaker, although some have ascribed their origins to as early as the mid-8th century. Some historians suggest that the Cossack people were of mixed ethnic origin, descending from East Slavs , Turks , Tatars , and others who settled or passed through

8512-512: The end of the 19th century. The Kalmyk and Buryat Cossacks also deserve mention . The Zaporizhian Sich became a vassal polity of the Polish–Lithuanian Commonwealth during feudal times. Under increasing pressure from the Polish–Lithuanian Commonwealth, in the mid-17th century the Sich declared an independent Cossack Hetmanate . The Hetmanate was initiated by a rebellion under Bohdan Khmelnytsky against Polish and Catholic domination, known as

8624-532: The era, Prince Aleksey Trubetskoy . After terrible losses, Trubetskoy was forced to withdraw to the town of Putyvl on the other side of the border. The battle is regarded as one of the Zaporizhian Cossacks' most impressive victories. In 1659, Yurii Khmelnytsky was elected hetman of the Zaporizhian Host/Hetmanate, with the endorsement of Moscow and supported by common Cossacks unhappy with

8736-605: The establishment of the Soviet Union , while others remained and assimilated into the Communist state. Cohesive Cossack-based units were organized and many fought for both Nazi Germany and the Soviet Union during World War II . After World War II, the Soviet Union disbanded the Cossack units within the Soviet Army, leading to the suppression of many Cossack traditions during the rule of Joseph Stalin and his successors. However, during

8848-673: The form of buried ground ice deposits are preserved on Zhokhov Island . The sea submerged the Great Arctic Plain (except for the New Siberian and other isolated islands) within a relatively short time span of 7,000 years during the Early–Middle Holocene . As noted by Digby and numerous later publications, this archipelago consists of a mixture of folded and faulted sedimentary and igneous rocks ranging in age from Precambrian to Pliocene . The Lyakhovsky Islands consist of

8960-489: The government, and often against its interests, as for example with their role in Moldavian affairs, and with the signing of a treaty with Emperor Rudolf II in the 1590s. Registered Cossacks formed a part of the Commonwealth army until 1699. Around the end of the 16th century, increasing Cossack aggression strained relations between the Commonwealth and the Ottoman Empire. Cossacks had begun raiding Ottoman territories during

9072-433: The greatest strain, and the strained mineral is more soluble than the rest of the grain. As a result, the contact points are dissolved away, allowing the grains to come into closer contact. Lithification follows closely on compaction, as increased temperatures at depth hasten deposition of cement that binds the grains together. Pressure solution contributes to cementing, as the mineral dissolved from strained contact points

9184-442: The hardness of individual grains, uniformity of grain size and friability of their structure, some types of sandstone are excellent materials from which to make grindstones , for sharpening blades and other implements. Non-friable sandstone can be used to make grindstones for grinding grain, e.g., gritstone . A type of pure quartz sandstone, orthoquartzite, with more of 90–95 percent of quartz, has been proposed for nomination to

9296-406: The ice in sleds drawn by dogs and reached the south coast of Great Lyakhovsky Island. Along the southern coast of this island he found well-preserved bones, ivory, peat, wood, and even a tree within 40-meter (130-foot) high sea cliffs that expose Late Pleistocene sediments. These sediments are cemented by permafrost and have accumulated periodically over the last 200,000 years. In September 2014,

9408-615: The locals in war, by raising the Cossack registry in times of hostility, and then radically decreasing it and forcing the Cossacks back into serfdom in times of peace. This institutionalized method of control bred discontent among the Cossacks. By the end of the 16th century, they began to revolt, in the uprisings of Kryshtof Kosynsky (1591–1593), Severyn Nalyvaiko (1594–1596), Hryhorii Loboda (1596), Marko Zhmailo (1625), Taras Fedorovych (1630), Ivan Sulyma (1635), Pavlo Pavliuk and Dmytro Hunia (1637), and Yakiv Ostrianyn and Karpo Skydan (1638). All were brutally suppressed and ended by

9520-412: The locals' land allotments and freedom of movement. In addition, the Polish-Lithuanian Commonwealth government attempted to impose Catholicism, and to Polonize the local Ukrainian population. The basic form of resistance and opposition by the locals and burghers was flight and settlement in the sparsely populated steppe. The major powers tried to exploit Cossack military power for their own purposes. In

9632-409: The military duty to serve in the irregular troops: Zaporozhian Cossacks were mostly infantry soldiers, using war wagons, while Don Cossacks were mostly cavalry soldiers. The various Cossack groups were organized along military lines, with large autonomous groups called hosts . Each host had a territory consisting of affiliated villages called stanitsas . They inhabited sparsely populated areas in

9744-490: The most resistant minerals to the weathering processes at the Earth's surface. Like uncemented sand , sandstone may be imparted any color by impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Because sandstone beds can form highly visible cliffs and other topographic features, certain colors of sandstone have become strongly identified with certain regions, such as

9856-596: The mouth of the Dnieper river. In 1615 and 1625, Cossacks razed suburbs of Constantinople , forcing the Ottoman Sultan to flee his palace. In 1637, the Zaporozhian Cossacks, joined by the Don Cossacks , captured the strategic Ottoman fortress of Azov , which guarded the Don. The Zaporizhian Cossacks became particularly strong in the first quarter of the 17th century under the leadership of hetman Petro Konashevych-Sahaidachny , who launched successful campaigns against

9968-493: The much lower temperatures and pressures associated with diagenesis of sedimentary rock, but diagenesis has cemented the rock so thoroughly that microscopic examination is necessary to distinguish it from metamorphic quartzite. The term orthoquartzite is used to distinguish such sedimentary rock from metaquartzite produced by metamorphism. By extension, the term orthoquartzite has occasionally been more generally applied to any quartz-cemented quartz arenite . Orthoquartzite (in

10080-424: The myth of Zemlya Sannikova or Sannikov Land . In 1886, Russian polar explorer and scientist Eduard Toll , during his first visit to the New Siberian Islands, thought that he had seen an unknown land north of Kotelny Island. He guessed that this was the so-called Zemlya Sannikova . Toll paid a further visit to the island group in the spring of 1892, accompanied by one Cossack and three natives. He traveled over

10192-580: The name to the Turkic word kazak , kozak , in which cosac meant 'free man' but also 'conqueror'. The ethnonym Kazakh is from the same Turkic root. In written sources, the name is first attested in the Codex Cumanicus from the 13th century. In English , Cossack is first attested in 1590. The origins of the Cossacks are disputed. Originally, the term referred to semi-independent Tatar groups ( qazaq or "free men") who inhabited

10304-464: The narrow sense) is often 99% SiO 2 with only very minor amounts of iron oxide and trace resistant minerals such as zircon , rutile and magnetite . Although few fossils are normally present, the original texture and sedimentary structures are preserved. The typical distinction between a true orthoquartzite and an ordinary quartz sandstone is that an orthoquartzite is so highly cemented that it will fracture across grains, not around them. This

10416-439: The newly created civil estate of Cossacks. Similar to the knights of medieval Europe in feudal times, or to the tribal Roman auxiliaries, the Cossacks had to obtain their cavalry horses , arms, and supplies for their military service at their own expense, the government providing only firearms and supplies. Lacking horses, the poor served in the Cossack infantry and artillery. In the navy alone, Cossacks served with other peoples as

10528-487: The nobility, especially various Lithuanian starostas . Merchants, peasants, and runaways from the Polish–Lithuanian Commonwealth, Muscovy , and Moldavia also joined the Cossacks. The first recorded sich prototype was formed by the starosta of Cherkasy and Kaniv , Dmytro Vyshnevetsky , who built a fortress on the island of Little Khortytsia on the banks of the Lower Dnieper in 1552. The Zaporozhian Host adopted

10640-456: The nominal suzerainty of various Eastern European states at the time, were allowed a great degree of self-governance in exchange for military service. Although numerous linguistic and religious groups came together to form the Cossacks, most of them coalesced and became East Slavic -speaking Orthodox Christians . The rulers of the Polish–Lithuanian Commonwealth and Russian Empire endowed Cossacks with certain special privileges in return for

10752-515: The north-east of Novaya Sibir. The New Siberian Islands are low-lying. Their highest point is located on Bennett island, with an elevation of 426 m. They are part of the East Siberian Lowland , forming a geographical continuum with the continental plains further south. The New Siberian Islands once formed major hills within the Great Arctic Plain that covered the northern part of Late Pleistocene " Beringia " between Siberia and Alaska during

10864-669: The private property of the Ruthenian Orthodox szlachta . Don Cossacks' raids on Crimea left Khmelnitsky without the aid of his usual Tatar allies. From the Russian perspective, the rebellion ended with the 1654 Treaty of Pereyaslav , in which, in order to overcome the Russian–Polish alliance against them, the Khmelnitsky Cossacks pledged their loyalty to the Russian Tsar . In return, the Tsar guaranteed them his protection; recognized

10976-638: The product of physical and chemical weathering of bedrock. Weathering and erosion are most rapid in areas of high relief, such as volcanic arcs , areas of continental rifting , and orogenic belts . Eroded sand is transported by rivers or by the wind from its source areas to depositional environments where tectonics has created accommodation space for sediments to accumulate. Forearc basins tend to accumulate sand rich in lithic grains and plagioclase . Intracontinental basins and grabens along continental margins are also common environments for deposition of sand. As sediments continue to accumulate in

11088-704: The red rock deserts of Arches National Park and other areas of the American Southwest . Rock formations composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs . Quartz-bearing sandstone can be changed into quartzite through metamorphism , usually related to tectonic compression within orogenic belts . Sandstones are clastic in origin (as opposed to either organic , like chalk and coal , or chemical , like gypsum and jasper ). The silicate sand grains from which they form are

11200-557: The reference was to people who were either Turkic or of undefined origin. Hrushevsky states that the Cossacks may have descended from the long-forgotten Antes , or from groups from the Berlad territory of the Brodnici in present-day Romania , then a part of the Grand Duchy of Halych. There, the Cossacks may have served as self-defence formations, organized to defend against raids conducted by neighbors. The first international mention of Cossacks

11312-513: The register, and from the Zaporizhian Host. This, together with intensified socioeconomic and national-religious oppression of the other classes in Ukrainian society, led to many Cossack uprisings in the 1630s. The nobility, which had obtained legal ownership of vast expanses of land on the Dnipro from the Polish kings, attempted to impose feudal dependency on the local population. Landowners utilized

11424-495: The resources of what was a naturally rich and fertile region teeming with cattle, wild animals, and fish. This lifestyle, based on subsistence agriculture , hunting, and either returning home in the winter or settling permanently, came to be known as the Cossack way of life. Crimean–Nogai slave raids in Eastern Europe caused considerable devastation and depopulation in this area. The Tatar raids also played an important role in

11536-525: The sacking of the then capital of the Hetmanate, Baturyn . The city was burnt and looted, and 11,000 to 14,000 of its inhabitants were killed. The destruction of the Hetmanate's capital was a signal to Mazepa and the Hetmanate's inhabitants of severe punishment for disloyalty to the Tsar's authority. The Zaporizhian Sich at Chortomlyk , which had existed since 1652, was also destroyed by Peter I's forces in 1709, in retribution for decision of its otaman Kost Hordiyenko , to ally with Mazepa. Under Russian rule,

11648-417: The sandstone are erased by the metamorphism. The grains are so tightly interlocked that when the rock is broken, it fractures through the grains to form an irregular or conchoidal fracture. Geologists had recognized by 1941 that some rocks show the macroscopic characteristics of quartzite, even though they have not undergone metamorphism at high pressure and temperature. These rocks have been subject only to

11760-420: The second part of the 16th century. The Polish government could not control them, but was held responsible as the men were nominally its subjects. In retaliation, Tatars living under Ottoman rule launched raids into the Commonwealth, mostly in the southeast territories. Cossack pirates responded by raiding wealthy trading port-cities in the heart of the Ottoman Empire, as these were just two days away by boat from

11872-469: The sixteenth century the Cossack were increasingly joined by Slavs such as Russians and Poles, Balto-slavic Lithuanians and people from today's Ukraine, thus becoming a Slav-Tatar ethnic hybrid. As the grand duchies of Moscow and Lithuania grew in power, new political entities appeared in the region. These included Moldavia and the Crimean Khanate . In 1261, Slavic people living in the area between

11984-481: The summer. Polar night conditions are present November through February, and, conversely, the Sun remains above the horizon continuously during summer months. Cossack The Cossacks are a predominantly East Slavic Eastern Christian people originating in the Pontic–Caspian steppe of eastern Ukraine and southern Russia . Historically, they were a semi- nomadic and semi-militarized people, who, while under

12096-486: The vast Steppe. Some Turkologists , however, argue that Cossacks are descendants of the native Cumans of Ukraine , who had lived there long before the Mongol invasion. some other just state that first Cossacks were Turkic origin according to Serhii Plokhy first Cossacks were of Turkic rather than Slavic stock. Christoph Baumer state that predesecessor from the thirteenth century on were mainly of Turkic stock, but from

12208-642: The very best and purest ivory". The abundant bones, even skeletons, of mammoth, rhinoceros, musk-ox, and other megafauna along with the mammoth ivory found in these islands are preserved by permafrost , in which they are encased. The permafrost periodically developed in Late Pleistocene loess , solifluction , pond , and stream sediments as they accumulated. The radiocarbon dating of bones, ivory, and plants, optically stimulated luminescence dating of enclosing sediments, and uranium-thorium dating of associated peats demonstrate that they accumulated over

12320-612: The world in constructing temples, churches, homes and other buildings, and in civil engineering . Although its resistance to weathering varies, sandstone is easy to work. That makes it a common building and paving material, including in asphalt concrete . However, some types that have been used in the past, such as the Collyhurst sandstone used in North West England , have had poor long-term weather resistance, necessitating repair and replacement in older buildings. Because of

12432-430: Was in 1492, when Crimean Khan Meñli I Giray complained to Grand Duke of Lithuania Alexander Jagiellon that his Cossack subjects from Kiev and Cherkasy had pillaged a Crimean Tatar ship: the duke ordered his "Ukrainian" (meaning borderland) officials to investigate, execute the guilty, and give their belongings to the khan. Sometime in the 16th century, there appeared the old Ukrainian Ballad of Cossack Holota , about

12544-475: Was secured. Consecutive treaties between the Ottoman Empire and the Polish–Lithuanian Commonwealth called for the governments to keep the Cossacks and Tatars in check, but neither enforced the treaties strongly. The Polish forced the Cossacks to burn their boats and stop raiding by sea, but the activity did not cease entirely. During this time, the Habsburg monarchy sometimes covertly hired Cossack raiders against
