At various times in the geologic past, the Earth had dense forests in low-lying areas. In these wetlands, the process of coalification began when dead plant matter was protected from oxidation , usually by mud or acidic water, and was converted into peat . The resulting peat bogs , which trapped immense amounts of carbon, were eventually deeply buried by sediments. Then, over millions of years,

The Kingdom of Poland emerged in 1025, and in 1569 cemented its long-standing association with Lithuania , thus forming
12702-574: The fifth largest EU country by land area, covering a combined area of 312,696 km (120,733 sq mi). The capital and largest city is Warsaw ; other major cities include Kraków , Wrocław , Łódź , Poznań , Gdańsk , and Szczecin . Prehistoric human activity on Polish soil dates to the Lower Paleolithic , with continuous settlement since the end of the Last Glacial Period . Culturally diverse throughout late antiquity , in
12876-494: The steam engine took over from the water wheel . In 1700, five-sixths of the world's coal was mined in Britain. Britain would have run out of suitable sites for watermills by the 1830s if coal had not been available as a source of energy. In 1947 there were some 750,000 miners in Britain, but the last deep coal mine in the UK closed in 2015. A grade between bituminous coal and anthracite
13050-434: The ' Polish Corridor ', the only internationally recognised Polish territory which afforded the country access to the sea. However, after World War II, the redrawing of Poland's borders and resulting 'shift' of the country's borders left it with a greatly expanded coastline, thus allowing for far greater access to the sea than was ever previously possible. The significance of this event, and importance of it to Poland's future as
13224-407: The 13th century; the wharf where the material arrived in London was known as Seacoal Lane, so identified in a charter of King Henry III granted in 1253. Initially, the name was given because much coal was found on the shore, having fallen from the exposed coal seams on cliffs above or washed out of underwater coal outcrops, but by the time of Henry VIII , it was understood to derive from the way it
13398-552: The 1794 Kościuszko Uprising , where a popular and distinguished general Tadeusz Kościuszko , who had several years earlier served under George Washington in the American Revolutionary War , led Polish insurgents. Despite the victory at the Battle of Racławice , his ultimate defeat ended Poland's independent existence for 123 years . In 1806, an insurrection organised by Jan Henryk Dąbrowski liberated western Poland ahead of Napoleon's advance into Prussia during
13572-576: The 1950s. Despite widespread objections, the new Polish government accepted the Soviet annexation of the pre-war eastern regions of Poland (in particular the cities of Wilno and Lwów ) and agreed to the permanent garrisoning of Red Army units on Poland's territory. Military alignment within the Warsaw Pact throughout the Cold War came about as a direct result of this change in Poland's political culture. In
13746-631: The Allies, providing much of the intelligence from Europe and beyond, Polish code breakers were responsible for cracking the Enigma cipher and Polish scientists participating in the Manhattan Project were co-creators of the American atomic bomb . In the east, the Soviet-backed Polish 1st Army distinguished itself in the battles for Warsaw and Berlin . The wartime resistance movement , and
13920-952: The Baltic, and the Czarna Hańcza flows into the Baltic through the Neman . While the great majority of Poland's rivers drain into the Baltic Sea, Poland's Beskids are the source of some of the upper tributaries of the Orava , which flows via the Váh and the Danube to the Black Sea . The eastern Beskids are also the source of some streams that drain through the Dniester to the Black Sea. Poland's rivers have been used since early times for navigation. The Vikings , for example, traveled up
14094-689: The Brave . In 1000, at the Congress of Gniezno , Bolesław obtained the right of investiture from Otto III, Holy Roman Emperor , who assented to the creation of additional bishoprics and an archdioceses in Gniezno. Three new dioceses were subsequently established in Kraków , Kołobrzeg , and Wrocław . Also, Otto bestowed upon Bolesław royal regalia and a replica of the Holy Lance , which were later used at his coronation as
14268-578: The Carboniferous, and suggested that climatic and tectonic factors were a more plausible explanation, reconstruction of ancestral enzymes by phylogenetic analysis corroborated a hypothesis that lignin degrading enzymes appeared in fungi approximately 200 MYa. One likely tectonic factor was the Central Pangean Mountains , an enormous range running along the equator that reached its greatest elevation near this time. Climate modeling suggests that
14442-678: The Carpathian montane conifer forest. Many animals that have since died out in other parts of Europe still survive in Poland, such as the wisent in the ancient woodland of the Białowieża Forest and in Podlaskie . Other such species include the brown bear in Białowieża , in the Tatras, and in the Beskids, the gray wolf and the Eurasian lynx in various forests, the moose in northern Poland, and
14616-587: The Central Pangean Mountains contributed to the deposition of vast quantities of coal in the late Carboniferous. The mountains created an area of year-round heavy precipitation, with no dry season typical of a monsoon climate. This is necessary for the preservation of peat in coal swamps. Coal is known from Precambrian strata, which predate land plants. This coal is presumed to have originated from residues of algae. Sometimes coal seams (also known as coal beds) are interbedded with other sediments in
14790-690: The Duchy of Warsaw was abolished at the Congress of Vienna in 1815 and its territory was divided into Russian Congress Kingdom of Poland , the Prussian Grand Duchy of Posen , and Austrian Galicia with the Free City of Kraków . In 1830, non-commissioned officers at Warsaw's Officer Cadet School rebelled in what was the November Uprising . After its collapse, Congress Poland lost its constitutional autonomy , army and legislative assembly. During
14964-564: The European Union were dismantled, allowing for full freedom of movement within most of the European Union. On 10 April 2010, the President of Poland Lech Kaczyński , along with 89 other high-ranking Polish officials died in a plane crash near Smolensk , Russia. In 2011, the ruling Civic Platform won parliamentary elections . In 2014, the Prime Minister of Poland , Donald Tusk ,
15138-603: The European scene, it came to characterise the full-fledged integration of Poland into the brotherhood of communist nations. The new communist government took control with the adoption of the Small Constitution on 19 February 1947. The Polish People's Republic ( Polska Rzeczpospolita Ludowa ) was officially proclaimed in 1952 . In 1956, after the death of Bolesław Bierut , the régime of Władysław Gomułka became temporarily more liberal, freeing many people from prison and expanding some personal freedoms. Collectivisation in
15312-608: The German occupation of Poland , including between 50,000 and 100,000 members of the Polish intelligentsia – academics, doctors, lawyers, nobility and priesthood. During the Warsaw Uprising alone, over 150,000 Polish civilians were killed, most were murdered by the Germans during the Wola and Ochota massacres. Around 150,000 Polish civilians were killed by Soviets between 1939 and 1941 during
15486-563: The Greek scientist Theophrastus (c. 371–287 BC): Among the materials that are dug because they are useful, those known as anthrakes [coals] are made of earth, and, once set on fire, they burn like charcoal [anthrakes]. They are found in Liguria ;... and in Elis as one approaches Olympia by the mountain road; and they are used by those who work in metals. Outcrop coal was used in Britain during
15660-570: The Hel Peninsula. Nearly all of Poland is swirled northward into the Baltic Sea by the Vistula , the Oder , and the tributaries of these two major rivers. About half the country is drained by the Vistula, which originates in the Silesian Beskids in far south-central Poland. The Vistula Basin includes most of the eastern half of the country and is drained by a system of rivers that mainly join
15834-547: The Polish People's Republic failed. A similar situation repeated itself in the 1970s under Edward Gierek , but most of the time persecution of anti-communist opposition groups persisted. Despite this, Poland was at the time considered to be one of the least oppressive states of the Eastern Bloc. Labour turmoil in 1980 led to the formation of the independent trade union " Solidarity " (" Solidarność "), which over time became
16008-599: The Polish-Jewish population. Towards the end of the 19th century, Congress Poland became heavily industrialised; its primary exports being coal, zinc , iron and textiles. In the aftermath of World War I , the Allies agreed on the reconstitution of Poland, confirmed through the Treaty of Versailles of June 1919. A total of 2 million Polish troops fought with the armies of the three occupying powers, and over 450,000 died. Following
16182-682: The Prussian rulers to pay tributes . The Jagiellonian dynasty also established dynastic control over the kingdoms of Bohemia (1471 onwards) and Hungary. In the south, Poland confronted the Ottoman Empire (at the Varna Crusade ) and the Crimean Tatars , and in the east helped Lithuania to combat Russia . Poland was developing as a feudal state, with a predominantly agricultural economy and an increasingly powerful landed nobility that confined
16356-555: The Russians at Klushino . Sigismund also countered the Ottoman Empire in the southeast; at Khotyn in 1621 Jan Karol Chodkiewicz achieved a decisive victory against the Turks, which ushered the downfall of Sultan Osman II . Sigismund's long reign in Poland coincided with the Silver Age . The liberal Władysław IV effectively defended Poland's territorial possessions but after his death
16530-526: The Sea, Marine Dumping, Nuclear Test Ban, Ozone Layer Protection, Ship Pollution, Wetlands Poland – in Europe (green & dark grey) – in the European Union (green) – [ Legend ] Poland , officially the Republic of Poland , is a country in Central Europe . It extends from the Baltic Sea in the north to the Sudetes and Carpathian Mountains in
16704-769: The Soviet Union's occupation of eastern Poland ( Kresy ), and another estimated 100,000 Poles were murdered by the Ukrainian Insurgent Army (UPA) between 1943 and 1944 in what became known as the Wołyń Massacres . Of all the countries in the war, Poland lost the highest percentage of its citizens: around 6 million perished – more than one-sixth of Poland's pre-war population – half of them Polish Jews. About 90% of deaths were non-military in nature. In 1945, Poland's borders were shifted westwards . Over two million Polish inhabitants of Kresy were expelled along
16878-602: The Vistula and the Oder in their longships . In the Middle Ages and in early modern times, when the Polish–Lithuanian Commonwealth was the breadbasket of Europe; the shipment of grain and other agricultural products down the Vistula toward Gdańsk and onward to other parts of Europe took on great importance. With almost ten thousand closed bodies of water covering more than 1 hectare (2.47 acres) each, Poland has one of
17052-461: The Vistula forms a large delta at the head of the latter. Sandbars with large dunes form lagoons and coastal lakes along much of the coast. The geological structure of Poland has been shaped by the continental collision of Europe and Africa over the past 60 million years on the one hand and the other by the Quaternary glaciations of northern Europe. Both processes shaped the Sudetes and
17226-472: The Vistula from the east. One of the tributaries, the Bug , defines 280 kilometers of Poland's eastern border with Ukraine and Belarus. The Oder and its major tributary, the Warta , and a few smaller rivers as Kłodnica , Mała Panew , Bóbr , Lusatian Neisse (Nysa Łużycka) and Ina , form a basin that drains the western third of Poland into the Bay of Szczecin . The drainage effect on a large part of Polish terrain
17400-540: The Warta River in Poznań . Nowadays the Polish lakes provide a location for the pursuit of water sports such as yachting and wind-surfing . The Polish Baltic coast is approximately 528 kilometres (328 mi) long and extends from Świnoujście on the islands of Usedom and Wolin in the west to Krynica Morska on the Vistula Spit in the east. For the most part, Poland has a smooth coastline, which has been shaped by
17574-567: The average thickness of the sand layer 40 metres (131 ft), with a maximum of 70 metres (230 ft), which made the fast and deep drainage very easy. The Baltic Sea activity in Słowiński National Park created sand dunes which in the course of time separated the bay from the sea. As waves and wind carry sand inland the dunes slowly move, at a speed of 3 to 10 metres (9.8 to 32.8 ft) meters per year. Some dunes are quite high – up to 30 metres (98 ft). The highest peak of
17748-493: The border with Ukraine, where the greatest seasonal differences occur and winter temperatures average 4.5 °C below those in western Poland. The hottest cities in Poland are Tarnów , Wrocław and Słubice . The average temperatures are rising. In the period of 1980 to 2010, there were 19 Decembers without snow, and in the period of 2000 to 2010 seven. December 2006 was the warmest one in Poland since 1779. In most of Poland, average temperatures rose by 3-5 degrees Celsius during
17922-488: The central lowlands, the lake region includes primeval forests - one of the last remaining in Europe and much of Poland's shrinking unspoiled natural habitat. Glacial action in this region formed lakes and low hills in the otherwise flat terrain adjacent to Lithuania and the Baltic Sea. Small lakes dot the entire northern half of Poland, and the glacial formations that characterize the lake region extend as much as 200 kilometers inland in western Poland. Wide river valleys divide
18096-590: The collision of diverse air masses above the country's surface. Maritime air moves across Western Europe , Arctic air sweeps down from the North Atlantic Ocean , and subtropical air arrives from the South Atlantic Ocean . Although the Polar air dominates for much of the year, its conjunction with warmer currents generally moderates temperatures and generates considerable precipitation , clouds, and fog. When
18270-533: The continual movement of sand by currents and winds. This continual erosion and deposition has formed cliffs, dunes, and spits, many of which have migrated landwards to close off former lagoons, such as Łebsko Lake in Słowiński National Park. Prior to the end of the Second World War and subsequent change in national borders , Poland had only a very small coastline; this was situated at the end of
18444-399: The country's historic regions, whereas those of the past two decades (to 1998) had been centred on and named for individual cities. The new units range in area from less than 10,000 square kilometres (3,900 sq mi) for Opole Voivodeship to more than 35,000 square kilometres (14,000 sq mi) for Masovian Voivodeship. Administrative authority at voivodeship level is shared between
18618-403: The decades up until World War I , a new political tradition was established in the country. Many exiled Polish activists, such as Ignacy Jan Paderewski , who would later become prime minister, returned home. A significant number of them then went on to take key positions in the newly formed political and governmental structures. Tragedy struck in 1922 when Gabriel Narutowicz , inaugural holder of
18792-552: The demand for craft labour spurred a migration of German and Flemish settlers into Poland, which was encouraged by the Polish dukes. In 1264, the Statute of Kalisz introduced unprecedented autonomy for the Polish Jews , who came to Poland fleeing persecution elsewhere in Europe. In 1320, Władysław I the Short became the first king of a reunified Poland since Przemysł II in 1296, and
18966-538: The doctrine of the so-called Polish Brethren , who separated from their Calvinist denomination and became the co-founders of global Unitarianism . The European Renaissance evoked under Sigismund I the Old and Sigismund II Augustus a sense of urgency in the need to promote a cultural awakening . During the Polish Golden Age , the nation's economy and culture flourished. The Italian-born Bona Sforza , daughter of
19140-634: The earliest evidence of European cheesemaking (5500 BC) was discovered in Polish Kuyavia , and the Bronocice pot is incised with the earliest known depiction of what may be a wheeled vehicle (3400 BC). The period spanning the Bronze Age and the Early Iron Age (1300 BC–500 BC) was marked by an increase in population density, establishment of palisaded settlements ( gords ) and the expansion of Lusatian culture . A significant archaeological find from
19314-535: The elections organised by the occupying Soviet authorities were falsified and were used to provide a veneer of legitimacy for Soviet hegemony over Polish affairs. The Soviet Union instituted a new communist government in Poland, analogous to much of the rest of the Eastern Bloc . As elsewhere in Communist Europe , the Soviet influence over Poland was met with armed resistance from the outset which continued into
19488-581: The end of World War I in 1918 with the creation of the Second Polish Republic , which emerged victorious in various conflicts of the interbellum period. In September 1939, the invasion of Poland by Germany and the Soviet Union marked the beginning of World War II , which resulted in the Holocaust and millions of Polish casualties . Forced into the Eastern Bloc in the global Cold War ,
19662-571: The environment , causing premature death and illness, and it is the largest anthropogenic source of carbon dioxide contributing to climate change . Fourteen billion tonnes of carbon dioxide were emitted by burning coal in 2020, which is 40% of total fossil fuel emissions and over 25% of total global greenhouse gas emissions . As part of worldwide energy transition , many countries have reduced or eliminated their use of coal power . The United Nations Secretary General asked governments to stop building new coal plants by 2020. Global coal use
19836-430: The evolution of the first trees . But bacteria and fungi did not immediately evolve the ability to decompose lignin, so the wood did not fully decay but became buried under sediment, eventually turning into coal. About 300 million years ago, mushrooms and other fungi developed this ability, ending the main coal-formation period of earth's history. Although some authors pointed at some evidence of lignin degradation during
20010-512: The factors involved in coalification, temperature is much more important than either pressure or time of burial. Subbituminous coal can form at temperatures as low as 35 to 80 °C (95 to 176 °F) while anthracite requires a temperature of at least 180 to 245 °C (356 to 473 °F). Although coal is known from most geologic periods , 90% of all coal beds were deposited in the Carboniferous and Permian periods. Paradoxically, this
20184-661: The far northwest, average less than 500 mm (19.7 in). In winter about half the precipitation in the lowlands and the entire amount in the mountains falls as snow. On average, precipitation in summer is twice of that in winter, providing a dependable supply of water for crops. The growing season is about 40 days longer in the southwest than in the northeast, where spring arrives latest. The highest temperature recorded in Poland occurred on 29 July 1921 at Prószków. The lowest temperature ever recorded in Poland occurred on 11 January 1940 in Siedlce. The highest winter temperature in Poland
20358-445: The first King of Poland in c. 1025 , when Bolesław received permission for his coronation from Pope John XIX . Bolesław also expanded the realm considerably by seizing parts of German Lusatia , Czech Moravia , Upper Hungary , and southwestern regions of the Kievan Rus' . The transition from paganism in Poland was not instantaneous and resulted in the pagan reaction of the 1030s . In 1031, Mieszko II Lambert lost
20532-453: The first elected king, approbated the Henrician Articles which obliged future monarchs to respect the rights of nobles. When he left Poland to become King of France , his successor, Stephen Báthory , led a successful campaign in the Livonian War , granting Poland more lands across the eastern shores of the Baltic Sea. State affairs were then headed by Jan Zamoyski , the Crown Chancellor . Stephen's successor, Sigismund III , defeated
20706-419: The first to be crowned at Wawel Cathedral in Kraków. Beginning in 1333, the reign of Casimir III the Great was marked by developments in castle infrastructure , army, judiciary and diplomacy . Under his authority, Poland transformed into a major European power; he instituted Polish rule over Ruthenia in 1340 and imposed quarantine that prevented the spread of Black Death . In 1364, Casimir inaugurated
20880-498: The form of iron pyrite (FeS 2 ). Being a dense mineral, it can be removed from coal by mechanical means, e.g. by froth flotation . Some sulfate occurs in coal, especially weathered samples. It is not volatilized and can be removed by washing. Minor components include: As minerals, Hg, As, and Se are not problematic to the environment, especially since they are only trace components. They become however mobile (volatile or water-soluble) when these minerals are combusted. Most coal
21054-478: The genocidal Generalplan Ost . Poland made the fourth-largest troop contribution in Europe, and its troops served both the Polish Government in Exile in the west and Soviet leadership in the east . Polish troops played an important role in the Normandy , Italian , North African Campaigns and Netherlands and are particularly remembered for the Battle of Britain and Battle of Monte Cassino . Polish intelligence operatives proved extremely valuable to
21228-447: The gently sloping foothills of the Sudeten and Carpathian mountain ranges and the uplands that connect the ranges in south-central Poland. The topography of this region is divided transversely into higher and lower elevations, reflecting its underlying geological structure. In the western section, the Silesia-Kraków Upthrust contains rich coal deposits. The third topographic area is located on either side of Poland's southern border and
21402-475: The heat and pressure of deep burial caused the loss of water, methane and carbon dioxide and increased the proportion of carbon. The grade of coal produced depended on the maximum pressure and temperature reached, with lignite (also called "brown coal") produced under relatively mild conditions, and sub-bituminous coal , bituminous coal , or anthracite coal (also called "hard coal" or "black coal") produced in turn with increasing temperature and pressure. Of
21576-410: The highest numbers of lakes in the world. In Europe, only Finland has a greater density of lakes. The largest lakes, covering more than 100 square kilometres (39 sq mi), are Lake Śniardwy and Lake Mamry in Masuria , and Lake Łebsko and Lake Drawsko in Pomerania . In addition to the lake districts in the north (in Masuria, Pomerania, Kashubia , Lubuskie, and Greater Poland ), there
21750-431: The increasing tendency of the anthracite to break with a conchoidal fracture , similar to the way thick glass breaks. As geological processes apply pressure to dead biotic material over time, under suitable conditions, its metamorphic grade or rank increases successively into: There are several international standards for coal. The classification of coal is generally based on the content of volatiles . However
21924-406: The lake region into three parts. In the northwest, Pomerania is located south of the Baltic coastal region and north of the Warta and Noteć rivers. Masuria occupies the remainder of northern Poland and features a string of larger lakes. Most of Poland's 9,300 lakes that are more than 10,000 square metres in area are located in the northern part of the lake region, where they occupy about 10% of
22098-422: The larger situated in the Gdańsk - Gdynia region, and the smaller near Szczecin in the far northwest. The northeastern region, also known as the Masurian Lake District with more than 2,000 lakes, is densely wooded and sparsely populated. To the south of the lake district, and across central Poland a vast region of plains stretches all the way to the Sudetes on the Czech and German borders southwest, and to
22272-413: The last three decades. These changes can be attributed to climate change . The average annual precipitation for the whole country is 600 mm (23.6 in), but isolated mountain areas receive as much as 1,300 mm (51.2 in) per year. The total is slightly higher in the southern uplands than in the central plains. A few areas, notably along the Vistula between Warsaw and the Baltic Sea and in
22446-518: The late Carboniferous ( Pennsylvanian ) and Permian times. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution . With the invention of the steam engine , coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energy and over a third of its electricity . Some iron and steel -making and other industrial processes burn coal. The extraction and burning of coal damages
22620-415: The moderating influences are lacking, winter temperatures in mountain valleys may drop to a minimum of −20 °C (−4 °F). The spring arrives slowly in March or April, bringing mainly sunny days after a period of alternating wintertime and springtime conditions. Summer, which extends from June to August, is generally less humid than winter. Showers and thunderstorms alternate with dry sunny weather that
22794-453: The morphology and some properties of the original plant. In many coals, individual macerals can be identified visually. Some macerals include: In coalification huminite is replaced by vitreous (shiny) vitrinite . Maturation of bituminous coal is characterized by bitumenization , in which part of the coal is converted to bitumen , a hydrocarbon-rich gel. Maturation to anthracite is characterized by debitumenization (from demethanation) and
22968-405: The most important distinction is between thermal coal (also known as steam coal), which is burnt to generate electricity via steam; and metallurgical coal (also known as coking coal), which is burnt at high temperature to make steel . Hilt's law is a geological observation that (within a small area) the deeper the coal is found, the higher its rank (or grade). It applies if the thermal gradient
23142-429: The mountain lakes of Czarny Staw pod Rysami (Black Lake below Mount Rysy), and Morskie Oko (the Marine Eye). The second highest mountain group in Poland are the Beskids, whose highest peak is Babia Góra , at 1,725 metres (5,659 ft). The next highest mountain group are the Giant Mountains in the Sudetes , whose highest point is Śnieżka , at 1,603 metres (5,259 ft); Śnieżnik Mountains whose highest point
23316-407: The nature of Carboniferous forests, which included lycophyte trees whose determinate growth meant that carbon was not tied up in heartwood of living trees for long periods. One theory suggested that about 360 million years ago, some plants evolved the ability to produce lignin , a complex polymer that made their cellulose stems much harder and more woody. The ability to produce lignin led to
23490-426: The new Prime Minister leading a coalition made up of Civic Coalition , Third Way , and The Left . Law and Justice became the leading opposition party. Poland covers an administrative area of 312,722 km (120,743 sq mi), and is the ninth-largest country in Europe . Approximately 311,895 km (120,423 sq mi) of the country's territory consists of land, 2,041 km (788 sq mi)
23664-403: The nobility. The failed attempts at government restructuring as well as the domestic turmoil provoked its neighbours to invade. In 1772, the First Partition of the Commonwealth by Prussia, Russia and Austria took place; an act which the Partition Sejm , under considerable duress, eventually ratified as a fait accompli . Disregarding the territorial losses, in 1773 a plan of critical reforms
23838-473: The north. There are over 120 areas designated as landscape parks , along with numerous nature reserves and other protected areas (e.g. Natura 2000 ). Present-day Poland is a country with favorable agricultural prospects, and over two million private farms. It is the leading producer of potatoes and rye in Europe, the world's largest producer of triticale , and one of the more important producers of barley, oats, sugar beets , flax, and various fruits. It
24012-455: The number of double bonds between carbon). As carbonization proceeds, aliphatic compounds convert to aromatic compounds . Similarly, aromatic rings fuse into polyaromatic compounds (linked rings of carbon atoms). The structure increasingly resembles graphene , the structural element of graphite. Chemical changes are accompanied by physical changes, such as decrease in average pore size. The macerals are coalified plant parts that retain
24186-430: The park – Rowokol (115 metres or 377 feet above sea level ) — is also an excellent observation point . Forests cover around 29.6% of Poland's territory as of 2021, making it the seventh most forested country in the EU, though the forest cover continues to increase year-on-year. The Polish government is carrying out a plan to increase forest coverage to 33% in 2050. The richness of Polish forests (per SoEF 2011 statistics)
24360-484: The period known as Golden Liberty , when the state was ruled by the seemingly free and equal Polish nobles . The 16th century saw Protestant Reformation movements making deep inroads into Polish Christianity, which resulted in the establishment of policies promoting religious tolerance, unique in Europe at that time. This tolerance allowed the country to avoid the religious turmoil and wars of religion that beset Europe. In Poland, Nontrinitarian Christianity became
24534-407: The population to private manorial farmstead known as folwarks . In 1493, John I Albert sanctioned the creation of a bicameral parliament composed of a lower house, the Sejm , and an upper house, the Senate . The Nihil novi act adopted by the Polish General Sejm in 1505, transferred most of the legislative power from the monarch to the parliament, an event which marked the beginning of
24708-456: The pre-combustion treatment, turbine technology (e.g. supercritical steam generator ) and the age of the plant. A few integrated gasification combined cycle (IGCC) power plants have been built, which burn coal more efficiently. Instead of pulverizing the coal and burning it directly as fuel in the steam-generating boiler, the coal is gasified to create syngas , which is burned in a gas turbine to produce electricity (just like natural gas
24882-414: The presence of Roman Legions sent to protect the amber trade . The Polish tribes emerged following the second wave of the Migration Period around the 6th century AD; they were Slavic and may have included assimilated remnants of peoples that earlier dwelled in the area. Beginning in the early 10th century, the Polans would come to dominate other Lechitic tribes in the region, initially forming
25056-400: The presidency, was assassinated at the Zachęta Gallery in Warsaw by a painter and right-wing nationalist Eligiusz Niewiadomski . In 1926, the May Coup , led by the hero of the Polish independence campaign Marshal Józef Piłsudski , turned rule of the Second Polish Republic over to the nonpartisan Sanacja ( Healing ) movement to prevent radical political organisations on both the left and
25230-407: The protohistory of Poland is a fortified settlement at Biskupin , attributed to the Lusatian culture of the Late Bronze Age (mid-8th century BC). Throughout antiquity (400 BC–500 AD), many distinct ancient populations inhabited the territory of present-day Poland, notably Celtic , Scythian , Germanic , Sarmatian , Baltic and Slavic tribes. Furthermore, archaeological findings confirmed
25404-427: The reacting groups are attached. Dehydration and decarboxylation take place early in coalification, while demethanation begins only after the coal has already reached bituminous rank. The effect of decarboxylation is to reduce the percentage of oxygen, while demethanation reduces the percentage of hydrogen. Dehydration does both, and (together with demethanation) reduces the saturation of the carbon backbone (increasing
25578-554: The resulting acid rain has caused forest damage; water pollution from industrial and municipal sources is also a problem, as is disposal of hazardous wastes. Disposal of the country's coal ash is aided by revegetation . Żołnierz et al. , 2016 find the return of bush species is naturally phytoremediating fly ash dumps. Environment - international agreements: party to: Air Pollution, Antarctic-Environmental Protocol, Antarctic Treaty, Biodiversity, Climate Change, Endangered Species, Environmental Modification, Hazardous Wastes, Law of
25752-441: The right from destabilizing the country. By the late 1930s, due to increased threats posed by political extremism inside the country, the Polish government became increasingly heavy-handed, banning a number of radical organisations, including communist and ultra-nationalist political parties, which threatened the stability of the country. World War II began with the Nazi German invasion of Poland on 1 September 1939, followed by
25926-444: The south, bordered by Lithuania and Russia to the northeast, Belarus and Ukraine to the east, Slovakia and the Czech Republic to the south, and Germany to the west. The territory is characterised by a varied landscape, diverse ecosystems, and temperate transitional climate. Poland is composed of sixteen voivodeships and is the fifth most populous member state of the European Union (EU), with over 38 million people, and
26100-408: The southwest, but individual readings in Poland's regions vary widely by season. On the highest mountain peaks, the mean temperature is below 0 °C (32 °F). The Baltic coast, influenced by moderating west winds, mostly in Świnoujście , Międzyzdroje , Dziwnów , Nowe Warpno , Police and Szczecin , has cooler summers and warmer winters. The other temperature extreme is in the southeast along
26274-399: The sulfur and most of the nitrogen is incorporated into the organic fraction in the form of organosulfur compounds and organonitrogen compounds . This sulfur and nitrogen are strongly bound within the hydrocarbon matrix. These elements are released as SO 2 and NO x upon combustion. They cannot be removed, economically at least, otherwise. Some coals contain inorganic sulfur, mainly in
26448-562: The summer of 1944 it initiated Operation Tempest , of which the Warsaw Uprising that began on 1 August 1944 is the best-known operation. Nazi German forces under orders from Adolf Hitler set up six German extermination camps in occupied Poland, including Treblinka , Majdanek and Auschwitz . The Germans transported millions of Jews from across occupied Europe to be murdered in those camps. Altogether, 3 million Polish Jews – approximately 90% of Poland's pre-war Jewry – and between 1.8 and 2.8 million ethnic Poles were killed during
26622-401: The surface area. The Baltic coastal plains are a low-lying region formed of sediments deposited by the sea. The coastline was shaped by the action of the rising sea after the Scandinavian ice sheet retreated. The two major inlets in the smooth coast are the Pomeranian Bay on the German border in the far northwest and the Gulf of Gdańsk in the east. The Oder River empties into the former, and
26796-442: The time. In the Baltic Sea region, the struggle of Poland and Lithuania with the Teutonic Knights continued and culminated at the Battle of Grunwald in 1410, where a combined Polish-Lithuanian army inflicted a decisive victory against them. In 1466, after the Thirteen Years' War , king Casimir IV Jagiellon gave royal consent to the Peace of Thorn , which created the future Duchy of Prussia under Polish suzerainty and forced
26970-561: The title of king and fled amidst the violence. The unrest led to the transfer of the capital to Kraków in 1038 by Casimir I the Restorer . In 1076, Bolesław II re-instituted the office of king, but was banished in 1079 for murdering his opponent, Bishop Stanislaus . In 1138, the country fragmented into five principalities when Bolesław III Wrymouth divided his lands among his sons. These were Lesser Poland , Greater Poland, Silesia , Masovia and Sandomierz , with intermittent hold over Pomerania . In 1226, Konrad I of Masovia invited
27144-433: The unemployment rate increased. Poland became a member of the Visegrád Group in 1991, and joined NATO in 1999. Poles then voted to join the European Union in a referendum in June 2003, with Poland becoming a full member on 1 May 2004, following the consequent enlargement of the organisation . Poland has joined the Schengen Area in 2007, as a result of which, the country's borders with other member states of
27318-405: The vast Commonwealth began declining from internal disorder and constant warfare. In 1648, the Polish hegemony over Ukraine sparked the Khmelnytsky Uprising , followed by the decimating Swedish Deluge during the Second Northern War , and Prussia's independence in 1657. In 1683, John III Sobieski re-established military prowess when he halted the advance of an Ottoman Army into Europe at
27492-415: The world's coal-generated electricity. Efforts around the world to reduce the use of coal have led some regions to switch to natural gas and renewable energy . In 2018 coal-fired power station capacity factor averaged 51%, that is they operated for about half their available operating hours. Coke is a solid carbonaceous residue that is used in manufacturing steel and other iron-containing products. Coke
27666-455: Was 8.3 billion tonnes in 2022, and is set to remain at record levels in 2023. To meet the Paris Agreement target of keeping global warming below 2 °C (3.6 °F) coal use needs to halve from 2020 to 2030, and "phasing down" coal was agreed upon in the Glasgow Climate Pact . The largest consumer and importer of coal in 2020 was China , which accounts for almost half the world's annual coal production, followed by India with about
27840-574: Was based on the trading of this commodity. Coal continues to arrive on beaches around the world from both natural erosion of exposed coal seams and windswept spills from cargo ships. Many homes in such areas gather this coal as a significant, and sometimes primary, source of home heating fuel. Coal consists mainly of a black mixture of diverse organic compounds and polymers. Of course, several kinds of coals exist, with variable dark colors and variable compositions. Young coals (brown coal, lignite) are not black. The two main black coals are bituminous, which
28014-451: Was carried to London by sea. In 1257–1259, coal from Newcastle upon Tyne was shipped to London for the smiths and lime -burners building Westminster Abbey . Seacoal Lane and Newcastle Lane, where coal was unloaded at wharves along the River Fleet , still exist. These easily accessible sources had largely become exhausted (or could not meet the growing demand) by the 13th century, when underground extraction by shaft mining or adits
28188-494: Was chosen to be President of the European Council , and resigned as prime minister. The 2015 and 2019 elections were won by the national-conservative Law and Justice Party (PiS) led by Jarosław Kaczyński , resulting in increased Euroscepticism and increased friction with the European Union. In December 2017, Mateusz Morawiecki was sworn in as the Prime Minister, succeeding Beata Szydlo , in office since 2015. President Andrzej Duda , supported by Law and Justice party,
28362-500: Was developed in the Soviet Union , or in an MHD topping cycle . However these are not widely used due to lack of profit. In 2017 38% of the world's electricity came from coal, the same percentage as 30 years previously. In 2018 global installed capacity was 2 TW (of which 1TW is in China) which was 30% of total electricity generation capacity. The most dependent major country is South Africa, with over 80% of its electricity generated by coal; but China alone generates more than half of
28536-408: Was developed. The alternative name was "pitcoal", because it came from mines. Cooking and home heating with coal (in addition to firewood or instead of it) has been done in various times and places throughout human history, especially in times and places where ground-surface coal was available and firewood was scarce, but a widespread reliance on coal for home hearths probably never existed until such
28710-434: Was during the Late Paleozoic icehouse , a time of global glaciation . However, the drop in global sea level accompanying the glaciation exposed continental shelves that had previously been submerged, and to these were added wide river deltas produced by increased erosion due to the drop in base level . These widespread areas of wetlands provided ideal conditions for coal formation. The rapid formation of coal ended with
28884-410: Was established, in which the Commission of National Education , the first government education authority in Europe, was inaugurated. Corporal punishment of schoolchildren was officially prohibited in 1783. Poniatowski was the head figure of the Enlightenment , encouraged the development of industries, and embraced republican neoclassicism . For his contributions to the arts and sciences he was awarded
29058-454: Was extensively funded by his sponsor and former lover, Empress Catherine II of Russia . The new king maneuvered between his desire to implement necessary modernising reforms, and the necessity to remain at peace with surrounding states. His ideals led to the formation of the 1768 Bar Confederation , a rebellion directed against the Poniatowski and all external influence, which ineptly aimed to preserve Poland's sovereignty and privileges held by
29232-501: Was founded before the 7th century BC by people of the Lusatian culture . Lakes have always played an important role in Polish history and continue to be of great importance to today's modern Polish society. The ancestors of today's Poles, the Polanie , built their first fortresses on islands in these lakes. The legendary Prince Popiel ruled from Kruszwica tower erected on the Lake Gopło . The first historically documented ruler of Poland, Duke Mieszko I , had his palace on an island in
29406-439: Was once known as "steam coal" as it was widely used as a fuel for steam locomotives . In this specialized use, it is sometimes known as "sea coal" in the United States. Small "steam coal", also called dry small steam nuts (DSSN), was used as a fuel for domestic water heating . Coal played an important role in industry in the 19th and 20th century. The predecessor of the European Union , the European Coal and Steel Community ,
29580-432: Was re-elected in the 2020 presidential election . As of November 2023 , the Russian invasion of Ukraine had led to 17 million Ukrainian refugees crossing the border to Poland. As of November 2023 , 0.9 million of those had stayed in Poland. In October 2023, the ruling Law and Justice (PiS) party won the largest share of the vote in the election , but lost its majority in parliament. In December 2023, Donald Tusk became
29754-422: Was recorded occurred on 25 February 2021 and lowest in summer was recorded on 21 July 1996. The highest temperature in January, 18.9 °C, was reported in Warsaw on 1 January 2022, at 11:30 AM. The New Year's Eve night was also among the warmest winter nights in history of the region, with temperatures reaching 17 °C in Słubice around midnight. Poland's current voivodeships (provinces) are largely based on
29928-447: Was to become Poland approximately 500,000 years ago, though the ensuing hostile climate prevented early humans from founding more permanent encampments. The arrival of Homo sapiens and anatomically modern humans coincided with the climatic discontinuity at the end of the Last Glacial Period ( Northern Polish glaciation 10,000 BC), when Poland became habitable. Neolithic excavations indicated broad-ranging development in that era;
30102-412: Was under the protection of the Apostolic See . The country's early origins were described by Gallus Anonymus in Gesta principum Polonorum , the oldest Polish chronicle. An important national event of the period was the martyrdom of Saint Adalbert , who was killed by Prussian pagans in 997 and whose remains were reputedly bought back for their weight in gold by Mieszko's successor, Bolesław I
30276-430: Was used for electricity generation. Coal burnt in coal power stations to generate electricity is called thermal coal . It is usually pulverized and then burned in a furnace with a boiler . The furnace heat converts boiler water to steam , which is then used to spin turbines which turn generators and create electricity. The thermodynamic efficiency of this process varies between about 25% and 50% depending on
