Radiocarbon dating of the Chandman remains ranges from 700 BCE to 300 BCE, a period spanning the Mongolian Iron Age. The Chandman culture has been linked to the nearby cultures at Sagly and Uyuk, and is part of the Scythian Saka culture. The Chandman population seems to have been in particularly good health, as their skeletal remains show little evidence for pathological disease. Dental and skeletal evidence show no signs of stress. However other analyses have shown injuries in

Their early reign

672-626: A troika was designated to take charge. Eventually Joseph Stalin , the General Secretary of the Communist Party , managed to suppress all opposition factions and consolidate power in his hands to become the country's dictator by the 1930s.

In

1008-463: A combination of external threats and internal instabilities caused the Roman state to splinter as regional armies acclaimed their generals as "soldier-emperors". One of these, Diocletian ( r.  284–305 ), seeing that the state was too big to be ruled by one man, attempted to fix the problem by instituting a Tetrarchy , or rule of four, and dividing the empire into eastern and western halves. Although

Manuel's death on 24 September 1180 left his 11-year-old son Alexios II Komnenos on

1344-460: A contested legacy to Roman identity and to associate negative connotations from ancient Latin literature. The adjective "Byzantine", which derived from Byzantion (Latinised as Byzantium ), the name of the Greek settlement Constantinople was established on, was only used to describe the inhabitants of that city; it did not refer to the empire, which they called Romanía —"Romanland". After

1512-501: A crisis. By 1991, economic and political turmoil began to boil over as the Baltic states chose to secede from the Soviet Union. On 17 March, a referendum was held, in which the vast majority of participating citizens voted in favour of changing the Soviet Union into a renewed federation . In June 1991, Boris Yeltsin became the first directly elected President in Russian history when he

2856-450: A small fleet of 100 ships to defend the capital, but other than that he was indifferent to the populace. He was finally overthrown when Isaac II Angelos , surviving an imperial assassination attempt, seized power with the aid of the people and had Andronikos killed. The reign of Isaac II, and more so that of his brother Alexios III , saw the collapse of what remained of the centralised machinery of Byzantine government and defence. Although

3024-417: A speedy and marked improvement. Gradually, however, Andronikos's reign deteriorated. The aristocrats were infuriated against him, and to make matters worse, Andronikos seemed to have become increasingly unbalanced; executions and violence became increasingly common, and his reign turned into a reign of terror.

3696-531: Is evidence that some Komnenian heirs had set up a semi-independent state in Trebizond before 1204. According to the historian Alexander Vasiliev , "the dynasty of the Angeloi, Greek in its origin, ... accelerated the ruin of the Empire, already weakened without and disunited within." In 1198, Pope Innocent III broached the subject of a new crusade through legates and encyclical letters. The stated intent of

3864-532: Is impossible to precisely date the foundation of the Byzantine Empire. In a series of conflicts between the third and first centuries   BC, the Roman Republic gradually established hegemony over the eastern Mediterranean , while its government ultimately transformed into the one-person rule of an emperor . The Roman Empire enjoyed a period of relative stability until the third century AD , when

4032-449: Is no consensus on a "foundation date" for the Byzantine Empire, if there was one at all. The growth of the study of "late antiquity" has led to some historians setting a start date in the seventh or eighth centuries. Others believe a "new empire" began during changes in c.  300   AD. Still others hold that these starting points are too early or too late, and instead begin c.  500 . Geoffrey Greatrex believes that it

In non-literary contexts Leo was less successful: the empire lost in Sicily and against the Bulgarians , while he provoked theological scandal by marrying four times in an attempt to father a legitimate heir. The early reign of that heir, Constantine VII , was tumultuous, as his mother Zoe , his uncle Alexander ,

4536-495: The Battle of Kursk in the summer of 1943. Another German failure was the Siege of Leningrad , in which the city was fully blockaded on land between 1941 and 1944 by German and Finnish forces, and suffered starvation and more than a million deaths, but never surrendered. Soviet forces steamrolled through Eastern and Central Europe in 1944–1945 and captured Berlin in May 1945. In August 1945,

4704-731: The Brusilov Offensive of the Imperial Russian Army almost completely destroyed the Austro-Hungarian Army . However, the already-existing public distrust of the regime was deepened by the rising costs of war, high casualties , and rumors of corruption and treason.

The emperor was the centre of the whole administration of the Empire, who the legal historian Kaius Tuori has said was "above the law, within the law, and the law itself"; with a power that is difficult to define and which does not align with our modern understanding of the separation of powers. The proclamations of the crowds of Constantinople, and the inaugurations of the patriarch from 457, would legitimise

12600-465: The Tetrarchy system quickly failed, the division of the empire proved an enduring concept. Constantine I ( r.  306–337 ) secured sole power in 324. Over the following six years, he rebuilt the city of Byzantium as a capital city , which was renamed Constantinople . Rome , the previous capital, was further from the important eastern provinces and in a less strategically important location; it

12768-528: The Turkish invaders at the Battle of Hyelion and Leimocheir , brought troops from the capital and was able to gather an army along the way, a sign that the Byzantine army remained strong and that the defensive program of western Asia Minor was still successful. John and Manuel pursued active military policies, and both deployed considerable resources on sieges and city defences; aggressive fortification policies were at

12936-594: The Ukrainian leader, Bohdan Khmelnytsky , offered to place Ukraine under the protection of the Russian tsar, Alexis ; whose acceptance of this offer led to another Russo-Polish War . Ultimately, Ukraine was split along the Dnieper , leaving the eastern part, ( Left-bank Ukraine and Kiev ) under Russian rule. In the east, the rapid Russian exploration and colonisation of vast Siberia continued, hunting for valuable furs and ivory. Russian explorers pushed eastward primarily along

13104-801: The Volga-Dnieper region of southern Russia and Ukraine as the urheimat of the Proto-Indo-Europeans . Early Indo-European migrations from the Pontic–Caspian steppe of Ukraine and Russia spread Yamnaya ancestry and Indo-European languages across large parts of Eurasia. Nomadic pastoralism developed in the Pontic–Caspian steppe beginning in the Chalcolithic . Remnants of these steppe civilizations were discovered in places such as Ipatovo , Sintashta , Arkaim , and Pazyryk , which bear

13272-604: The West Eurasian Sintashta culture , and an additional 43% from an East Eurasian population from Lake Baikal ( Baikal EBA ), Mongolia . 7% of their ancestry was related to the Bactria-Margiana Archaeological Complex population of Central Asia, which was closely related to Neolithic populations of the Iranian plateau and the Caucasus hunter-gatherers . Strong evidence of sex bias was found in

13440-597: The West, Khosrow I of the Sasanian Empire invaded Byzantine territory and sacked Antioch in 540. Meanwhile, the emperor's internal reforms and policies began to falter, not helped by a devastating plague that killed a large proportion of the population and severely weakened the empire's social and financial stability. The most difficult period of the Ostrogothic war, against their king Totila , came during this decade, while divisions among Justinian's advisors undercut

13608-401: The West. Zeno ( r.  474–491 ) convinced the problematic Ostrogoth king Theodoric to take control of Italy from Odoacer, which he did; dying with the empire at peace, Zeno was succeeded by Anastasius I ( r.  491–518 ). Although his Monophysitism brought occasional issues, Anastasius was a capable administrator and instituted several successful financial reforms including

13776-581: The Western provinces to achieve an economic revival that continued until the close of the century. It has been argued that Byzantium under the Komnenian rule was more prosperous than at any time since the Persian invasions of the 7th century. During the 12th century, population levels rose and extensive tracts of new agricultural land were brought into production. Archaeological evidence from both Europe and Asia Minor shows

13944-652: The Xiongnu essentially derived from the Eastern Eurasian Slab Grave culture , while retainers of comparatively lower status had high genetic heterogeneity, representing influxes from the many parts of the Xiongnu Empire, and included Chandman-related individuals. Russia Russia , or the Russian Federation , is a country spanning Eastern Europe and North Asia . It is the largest country in

14112-522: The abolition of the chrysargyron tax . He was the first emperor to die with no serious problems affecting his empire since Diocletian. The reign of Justinian I was a watershed in Byzantine history. Following his accession in 527, the law-code was rewritten as the influential Corpus Juris Civilis and Justinian produced extensive legislation on provincial administration; he reasserted imperial control over religion and morality through purges of non-Christians and "deviants"; and having ruthlessly subdued

14280-569: The administration's response. He also did not fully heal the divisions in Chalcedonian Christianity , as the Second Council of Constantinople failed to make a real difference. Justinian died in 565; his reign saw more success than that of any other Byzantine emperor, yet he left his empire under massive strain. Financially and territorially overextended, Justin II ( r.  565–578 )

14448-463: The ancestry of the Chandman population. Western Steppe Herder ancestry (from a Sintashta -like source) in the Chandman population was inherited from more male than female ancestors. Chandman males were found to be equally divided between the West Eurasian haplogroup R1a and East Eurasian haplogroup Q-L275 . Jeong, et al. found that the early Western Xiongnu derived 93% of their ancestry from

14616-568: The aristocracy turned into wholesale slaughter, while the emperor resorted to ever more ruthless measures to shore up his regime. Despite his military background, Andronikos failed to deal with Isaac Komnenos of Cyprus, Béla III of Hungary who reincorporated Croatian territories into Hungary, and Stephen Nemanja of Serbia who declared his independence from the Byzantine Empire. Yet, none of these troubles compared to William II of Sicily 's invasion force of 300 ships and 80,000 men, arriving in 1185 and sacking Thessalonica . Andronikos mobilised

14784-576: The capital Moscow. In 1612, the Poles were forced to retreat by the Russian volunteer corps, led by merchant Kuzma Minin and prince Dmitry Pozharsky . The Romanov dynasty acceded to the throne in 1613 by the decision of the Zemsky Sobor, and the country started its gradual recovery from the crisis. Russia continued its territorial growth through the 17th century, which was the age of the Cossacks . In 1654,

14952-488: The capital, and Alexios Angelos was elevated to the throne as Alexios IV along with his blind father Isaac. Alexios IV and Isaac II were unable to keep their promises and were deposed by Alexios V . The crusaders again took the city on 13 April 1204 , and Constantinople was subjected to pillage and massacre by the rank and file for three days. Many priceless icons, relics and other objects later turned up in Western Europe ,

15120-464: The city had collapsed so severely that it was now little more than a cluster of villages separated by fields. On 2 April 1453, Sultan Mehmed 's army of 80,000 men and large numbers of irregulars laid siege to the city. Despite a desperate last-ditch defence of the city by the massively outnumbered Christian forces (c. 7,000 men, 2,000 of whom were foreign), Constantinople finally fell to the Ottomans after

15288-530: The control of the Golden Horde and consolidated the whole of northern Rus' under Moscow's dominion, and was the first Russian ruler to take the title "Grand Duke of all Rus'". After the fall of Constantinople in 1453, Moscow claimed succession to the legacy of the Eastern Roman Empire . Ivan III married Sophia Palaiologina , the niece of the last Byzantine emperor Constantine XI , and made

15456-476: The country has experienced democratic backsliding and become an authoritarian dictatorship . Russia has been militarily involved in a number of conflicts in former Soviet states and other countries , including its war with Georgia in 2008 and its war with Ukraine since 2014, which has involved the internationally unrecognised annexations of Ukrainian territory including Crimea in 2014 and four other regions in 2022 during an ongoing invasion . Russia

15624-882: The country was more often referred to by its inhabitants as Rus ' , the Russian land ( Russkaia zemlia ), or the Muscovite state ( Moskovskoe gosudarstvo ), among other variations. In 1721, Peter the Great changed the name of the state from Tsardom of Russia ( Russian : Русское царство , romanized :  Russkoye tsarstvo ) or Tsardom of Muscovy ( Russian : Московское царство , romanized :  Moskovskoye tsarstvo ) to Russian Empire ( Rossiiskaia imperiia ). There are several words in Russian which translate to "Russians" in English. The noun and adjective русский , russkiy refers to ethnic Russians . The adjective российский , rossiiskiy denotes Russian citizens regardless of ethnicity. The same applies to

15792-446: The crucial Battle of Molodi . The death of Ivan's sons marked the end of the ancient Rurik dynasty in 1598, and in combination with the disastrous famine of 1601–1603 , led to a civil war, the rule of pretenders, and foreign intervention during the Time of Troubles in the early 17th century. The Polish–Lithuanian Commonwealth , taking advantage, occupied parts of Russia, extending into

15960-589: The crusade was to conquer Egypt , the centre of Muslim power in the Levant. The Crusader army arrived at Venice in the summer of 1202 and hired the Venetian fleet to transport them to Egypt. As a payment to the Venetians, they captured the (Christian) port of Zara in Dalmatia , which was a vassal city of Venice, it had rebelled and placed itself under Hungary's protection in 1186. Shortly afterward, Alexios IV Angelos , son of

16128-499: The deposed and blinded Emperor Isaac II, made contact with the Crusaders. Alexios offered to reunite the Byzantine church with Rome, pay the Crusaders 200,000 silver marks, join the crusade, and provide all the supplies they needed to reach Egypt. The crusaders arrived at Constantinople in the summer of 1203 and quickly attacked , starting a major fire that damaged large parts of the city, and briefly seized control. Alexios III fled from

16296-559: The earliest known traces of horses in warfare . The genetic makeup of speakers of the Uralic language family in northern Europe was shaped by migration from Siberia that began at least 3,500 years ago. In the 3rd to 4th centuries CE, the Gothic kingdom of Oium existed in southern Russia, which was later overrun by Huns . Between the 3rd and 6th centuries CE, the Bosporan Kingdom , which

16464-471: The east by allowing the Goths to settle in Roman territory; he also twice intervened in the western half, defeating the usurpers Magnus Maximus and Eugenius in 388 and 394 respectively. He actively condemned paganism , confirmed the primacy of Nicene Christianity over Arianism , and established Christianity as the Roman state religion . He was the last emperor to rule both the western and eastern halves of

16632-433: The east to Calabria in southern Italy in the west. Many successes had been achieved, ranging from the conquest of Bulgaria to the annexation of parts of Georgia and Armenia, and the reconquests of Crete , Cyprus , and the important city of Antioch . These were not temporary tactical gains but long-term reconquests. At the same time, Byzantium was faced with new enemies. Its provinces in southern Italy were threatened by

16800-681: The eastern parts largely retained their preexisting Hellenistic culture . This created a dichotomy between the Greek East and Latin West . These cultural spheres continued to diverge after Constantine I ( r.  324–337 ) moved the capital to Constantinople and legalised Christianity . Under Theodosius I ( r. 379–395 ), Christianity became the state religion , and other religious practices were proscribed . Greek gradually replaced Latin for official use as Latin fell into disuse. The empire experienced several cycles of decline and recovery throughout its history, reaching its greatest extent after

16968-673: The efforts of Russian explorers , developing into the Russian Empire , which remains the third-largest empire in history . However, with the Russian Revolution in 1917, Russia's monarchic rule was abolished and eventually replaced by the Russian SFSR —the world's first constitutionally socialist state . Following the Russian Civil War , the Russian SFSR established the Soviet Union with three other Soviet republics , within which it

17136-527: The emperor's role as the leader of the Christian world, John marched into the Holy Land at the head of the combined forces of the empire and the Crusader states; yet despite his efforts in leading the campaign, his hopes were disappointed by the treachery of his Crusader allies. In 1142, John returned to press his claims to Antioch, but he died in the spring of 1143 following a hunting accident. John's chosen heir

17304-523: The empire's eastern defences. The emergency lent weight to the military aristocracy in Anatolia, who in 1068 secured the election of one of their own, Romanos Diogenes , as emperor. In the summer of 1071, Romanos undertook a massive eastern campaign to draw the Seljuks into a general engagement with the Byzantine army. At the Battle of Manzikert , Romanos suffered a surprise defeat against Sultan Alp Arslan and

17472-492: The empire's fall, early modern scholars referred to the empire by many names, including the "Empire of Constantinople", the "Empire of the Greeks", the "Eastern Empire", the "Late Empire", the "Low Empire", and the "Roman Empire". The increasing use of "Byzantine" and "Byzantine Empire" likely started with the 15th-century historian Laonikos Chalkokondyles , whose works were widely propagated, including by Hieronymus Wolf . "Byzantine"

17640-544: The empire, gaining only short-term success. To avoid another sacking of the capital by the Latins, he forced the Church to submit to Rome, again a temporary solution for which the peasantry hated Michael and Constantinople. The efforts of Andronikos II and later his grandson Andronikos III marked Byzantium's last genuine attempts to restoring the glory of the empire. However, the use of mercenaries by Andronikos II often backfired, with

17808-460: The empire; after his death, the West would be destabilised by a succession of "soldier-emperors", unlike the East, where administrators would continue to hold power. Theodosius II ( r.  408–450 ) largely left the rule of the east to officials such as Anthemius , who constructed the Theodosian Walls to defend Constantinople, now firmly entrenched as Rome's capital. Theodosius' reign

17976-514: The end of the Norman threat during Alexios' reign. Alexios's son John II Komnenos succeeded him in 1118 and ruled until 1143. John was a pious and dedicated emperor who was determined to undo the damage to the empire suffered at the Battle of Manzikert half a century earlier. Famed for his piety and his remarkably mild and just reign, John was an exceptional example of a moral ruler at a time when cruelty

18144-659: The enemies that surrounded it. To maintain his campaigns against the Latins, Michael pulled troops from Asia Minor and levied crippling taxes on the peasantry, causing much resentment. Massive construction projects were completed in Constantinople to repair the damage of the Fourth Crusade, but none of these initiatives were of any comfort to the farmers in Asia Minor suffering raids from Muslim ghazis. Rather than holding on to his possessions in Asia Minor, Michael chose to expand

18312-464: The fall of the west during the reign of Justinian I ( r. 527–565 ), who briefly reconquered much of Italy and the western Mediterranean coast . The appearance of plague and a devastating war with Persia exhausted the empire's resources; the early Muslim conquests that followed saw the loss of the empire's richest provinces— Egypt and Syria —to the Rashidun Caliphate . In 698, Africa

18480-474: The first Europeans to reach and colonise Alaska . In 1803–1806, the first Russian circumnavigation was made. In 1820, a Russian expedition discovered the continent of Antarctica . During the Napoleonic Wars , Russia joined alliances with various European powers, and fought against France. The French invasion of Russia at the height of Napoleon's power in 1812 reached Moscow, but eventually failed as

18648-549: The first Russian feudal representative body (the Zemsky Sobor ), revamped the military, curbed the influence of the clergy, and reorganised local government. During his long reign, Ivan nearly doubled the already large Russian territory by annexing the three Tatar khanates: Kazan and Astrakhan along the Volga , and the Khanate of Sibir in southwestern Siberia. Ultimately, by the end of

18816-520: The first half of the 19th century, Russia also conquered the Caucasus . Catherine's successor, her son Paul , was unstable and focused predominantly on domestic issues . Following his short reign, Catherine's strategy was continued with Alexander I's (1801–1825) wresting of Finland from the weakened Sweden in 1809, and of Bessarabia from the Ottomans in 1812. In North America, the Russians became

18984-569: The former Byzantine possessions. Although Venice was more interested in commerce than conquering territory, it took key areas of Constantinople, and the Doge took the title of " Lord of a Quarter and Half a Quarter of the Roman Empire ". After the sack of Constantinople in 1204 by Latin crusaders, two Byzantine successor states were established: the Empire of Nicaea and the Despotate of Epirus . A third,

19152-544: The fort, allowing the Ottomans (who were hired as mercenaries during the civil war by John VI Kantakouzenos ) to establish themselves in Europe. By the time the Byzantine civil wars had ended, the Ottomans had defeated the Serbians and subjugated them as vassals. Following the Battle of Kosovo , much of the Balkans became dominated by the Ottomans. Constantinople by this stage was underpopulated and dilapidated. The population of

19320-485: The government, which led to the rise of Russian oligarchs . Many of the newly rich moved billions in cash and assets outside of the country in an enormous capital flight . The depression of the economy led to the collapse of social services—the birth rate plummeted while the death rate skyrocketed, and millions plunged into poverty; while extreme corruption, as well as criminal gangs and organised crime rose significantly. In late 1993, tensions between Yeltsin and

19488-431: The heart of their imperial military policies. Despite the defeat at Myriokephalon, the policies of Alexios, John and Manuel resulted in vast territorial gains, increased frontier stability in Asia Minor, and secured the stabilisation of the empire's European frontiers. From c.  1081 to c.  1180 , the Komnenian army assured the empire's security, enabling Byzantine civilisation to flourish. This allowed

19656-708: The later part of his reign, John focused his activities on the East, personally leading numerous campaigns against the Turks in Asia Minor. His campaigns fundamentally altered the balance of power in the East, forcing the Turks onto the defensive, while retaking many towns, fortresses, and cities across the peninsula for the Byzantines. He defeated the Danishmend Emirate of Melitene and reconquered all of Cilicia , while forcing Raymond of Poitiers , Prince of Antioch, to recognise Byzantine suzerainty. In an effort to demonstrate

19824-525: The latter deliberately starved to death or otherwise killed 3.3 million Soviet POWs , and a vast number of civilians, as the " Hunger Plan " sought to fulfil Generalplan Ost . Although the Wehrmacht had considerable early success, their attack was halted in the Battle of Moscow . Subsequently, the Germans were dealt major defeats first at the Battle of Stalingrad in the winter of 1942–1943, and then in

19992-669: The meantime, both the Bolsheviks and White movement carried out campaigns of deportations and executions against each other, known respectively as the Red Terror and White Terror . By the end of the violent civil war, Russia's economy and infrastructure were heavily damaged, and as many as 10 million perished during the war, mostly civilians. Millions became White émigrés , and the Russian famine of 1921–1922 claimed up to five million victims. On 30 December 1922, Lenin and his aides formed

20160-418: The measures he took to reform the government of the empire have been praised by historians. According to the historian George Ostrogorsky , Andronikos was determined to root out corruption: under his rule, the sale of offices ceased; selection was based on merit, rather than favouritism; and officials were paid an adequate salary to reduce the temptation of bribery. In the provinces, Andronikos's reforms produced

20328-635: The mid-13th century it had lost much of southern Anatolia. The weakening of the Sultanate of Rûm following the Mongol invasion in 1242–1243 allowed many beyliks and ghazis to set up their own principalities in Anatolia, weakening the Byzantine hold on Asia Minor. Two centuries later, one of the Beys of these beyliks, Osman I , would establish the Ottoman Empire that would eventually conquer Constantinople. However,

20496-596: The more recently coined noun россиянин , rossiianyn , "Russian" in the sense of citizen of the Russian state. According to the Primary Chronicle , the word Rus' is derived from the Rus' people , who were a Swedish tribe, and where the three original members of the Rurikid dynasty came from. The Finnish word for Swedes, ruotsi , has the same origin. Later archeological studies mostly confirmed this theory. The first human settlement on Russia dates back to

20664-542: The most capable Byzantine emperors, withstood continued Arab attacks, civil unrest, and natural disasters, and reestablished the state as a major regional power. Leo's reign produced the Ecloga , a new code of law to succeed that of Justinian II, and continued to reform the "theme system" in order to lead offensive campaigns against the Muslims, culminating in a decisive victory in 740 . Constantine overcame an early civil war against his brother-in-law Artabasdos , made peace with

20832-567: The new Abbasid Caliphate , campaigned successfully against the Bulgars, and continued to make administrative and military reforms. However, due to both emperors' support for the Byzantine Iconoclasm , which opposed the use of religious icons , they were later vilified by Byzantine historians; Constantine's reign also saw the loss of Ravenna to the Lombards , and the beginning of a split with

21000-466: The newly-formed Arabic Rashidun Caliphate . By Heraclius' death in 641, the empire had been severely reduced economically as well as territorially—the loss of the wealthy eastern provinces had deprived Constantinople of three-quarters of its revenue. The next seventy-five years are poorly documented. Arab raids into Asia Minor began almost immediately, and the Byzantines resorted to holding fortified centres and avoiding battle at all costs; although it

21168-577: The north-east. Led by Prince Alexander Nevsky , Novgorodians repelled the invading Swedes in the Battle of the Neva in 1240, as well as the Germanic crusaders in the Battle on the Ice in 1242. Kievan Rus' finally fell to the Mongol invasion of 1237–1240, which resulted in the sacking of Kiev and other cities, as well as the death of a major part of the population. The invaders, later known as Tatars , formed

21336-601: The obstinate resistance in combination with the bitterly cold Russian winter led to a disastrous defeat of invaders, in which the pan-European Grande Armée faced utter destruction. Led by Mikhail Kutuzov and Michael Andreas Barclay de Tolly , the Imperial Russian Army ousted Napoleon and drove throughout Europe in the War of the Sixth Coalition , ultimately entering Paris. Alexander I controlled Russia's delegation at

21504-538: The official line. The continued internal struggle in the Bolshevik party culminated in the Great Purge . Under Stalin's leadership, the government launched a command economy , industrialisation of the largely rural country , and collectivisation of its agriculture . During this period of rapid economic and social change, millions of people were sent to penal labour camps , including many political convicts for their suspected or real opposition to Stalin's rule; and millions were deported and exiled to remote areas of

21672-406: The outset of his reign, Alexios faced a formidable attack from the Normans under Guiscard and his son Bohemund of Taranto , who captured Dyrrhachium and Corfu and laid siege to Larissa in Thessaly . Guiscard's death in 1085 temporarily eased the Norman problem. The following year, the Seljuq sultan died, and the sultanate was split due to internal rivalries. By his own efforts, Alexios defeated

21840-521: The patriarch Nicholas , the powerful Simeon I of Bulgaria , and other influential figures jockeyed for power. In 920, the admiral Romanos I used his fleet to secure power, crowning himself and demoting Constantine to the position of junior co-emperor. His reign, which brought peace with Bulgaria and successes in the east under the general John Kourkouas , was ended in 944 by the machinations of his sons, whom Constantine soon usurped in turn. Constantine's ineffectual sole rule has often been construed as

22008-443: The polity as the "Roman Empire" and to themselves as "Romans". Due to the imperial seat's move from Rome to Byzantium , the adoption of state Christianity , and the predominance of Greek instead of Latin , modern historians continue to make a distinction between the earlier Roman Empire and the later Byzantine Empire . During the earlier Pax Romana period, the western parts of the empire became increasingly Latinised , while

22176-410: The pope and Western Christian kingdoms, and he successfully handled the passage of the crusaders through his empire. In the East, Manuel suffered a major defeat in 1176 at the Battle of Myriokephalon against the Turks. These losses were quickly recovered, and in the following year Manuel's forces inflicted a defeat upon a force of "picked Turks". The Byzantine commander John Vatatzes , who destroyed

22344-439: The ports of southern Italy, he sent an expedition to Italy in 1155, but disputes within the coalition led to the eventual failure of the campaign. Despite this military setback, Manuel's armies successfully invaded the southern parts of the Kingdom of Hungary in 1167, defeating the Hungarians at the Battle of Sirmium . By 1168, nearly the whole of the eastern Adriatic coast lay in Manuel's hands. Manuel made several alliances with

22512-407: The press ; the country also has high levels of perceived corruption . As of 2024, Russia has a high-income economy which ranks eleventh in the world by nominal GDP and fourth at purchasing power parity , relying on its vast mineral and energy resources ; the world's second-largest for oil production and natural gas production . Russia is home to 32 UNESCO World Heritage Sites . According to

22680-441: The reconstituted empire would wield only regional power during its final two centuries of existence. Its remaining territories were progressively annexed by the Ottomans in perennial wars fought throughout the 14th and 15th centuries. The fall of Constantinople to the Ottomans in 1453 ultimately brought the empire to an end. Many refugees who had fled the city after its capture settled in Italy and throughout Europe, helping to ignite

22848-420: The rivalry between the two major European empires came to be known as the Great Game . The late 19th century saw the rise of various socialist movements in Russia. Alexander II was assassinated in 1881 by revolutionary terrorists. The reign of his son Alexander III (1881–1894) was less liberal but more peaceful. Under last Russian emperor, Nicholas II (1894–1917), the Revolution of 1905

23016-432: The rouble. High budget deficits coupled with increasing capital flight and inability to pay back debts, caused the 1998 Russian financial crisis , which resulted in a further GDP decline. Byzantine Empire The Byzantine Empire , also referred to as the Eastern Roman Empire , was the continuation of the Roman Empire centred in Constantinople during late antiquity and the Middle Ages . The eastern half of

23184-611: The seat of the Metropolitan of the Russian Orthodox Church moved to Moscow in 1325, its influence increased. Moscow's last rival, the Novgorod Republic , prospered as the chief fur trade centre and the easternmost port of the Hanseatic League . Led by Prince Dmitry Donskoy of Moscow, the united army of Russian principalities inflicted a milestone defeat on the Mongol-Tatars in the Battle of Kulikovo in 1380. Moscow gradually absorbed its parent duchy and surrounding principalities, including formerly strong rivals such as Tver and Novgorod . Ivan III ("the Great") threw off

23352-406: The state of the Golden Horde , which ruled over Russia for the next two centuries. Only the Novgorod Republic escaped foreign occupation after it agreed to pay tribute to the Mongols. Galicia-Volhynia would later be absorbed by Lithuania and Poland , while the Novgorod Republic continued to prosper in the north. In the northeast, the Byzantine-Slavic traditions of Kievan Rus' were adapted to form

23520-491: The throne. Alexios was highly incompetent in the office, and with his mother Maria of Antioch 's Frankish background, his regency was unpopular. Eventually, Andronikos I Komnenos , a grandson of Alexios I, overthrew Alexios II in a violent coup d'état . After eliminating his potential rivals, he had himself crowned as co-emperor in September 1183. He eliminated Alexios II and took his 12-year-old wife Agnes of France for himself. Andronikos began his reign well; in particular,

23688-523: The time Chechen separatists declared independence in the early 1990s, an intermittent guerrilla war was fought between the rebel groups and Russian forces. Terrorist attacks against civilians were carried out by Chechen separatists, claiming the lives of thousands of Russian civilians. After the dissolution of the Soviet Union, Russia assumed responsibility for settling the latter's external debts. In 1992, most consumer price controls were eliminated, causing extreme inflation and significantly devaluing

23856-442: The unpopular Irene was overthrown by Nikephoros I ; he reformed the empire's administration but died in battle against the Bulgars in 811. Military defeats and societal disorder, especially the resurgence of iconoclasm, characterised the next eighteen years. Stability was somewhat restored during the reign of Theophilos ( r.  829–842 ), who exploited economic growth to complete construction programs, including rebuilding

24024-408: The west, the warlord Odoacer deposed Romulus Augustulus in 476, killed his titular successor Julius Nepos in 480, and the office of western emperor was formally abolished. Through a combination of luck, cultural factors, and political decisions, the Eastern empire never suffered from rebellious barbarian vassals and was never ruled by barbarian warlords—the problems which ensured the downfall of

24192-450: The world by area , extending across eleven time zones and sharing land borders with fourteen countries . It is the world's ninth-most populous country and Europe's most populous country . Russia is a highly urbanised country including 16 population centres with over a million inhabitants. Its capital and largest city is Moscow . Saint Petersburg is Russia's second-largest city and its cultural capital . The East Slavs emerged as

24360-422: The zenith of Byzantine learning , but while several works were compiled, they were largely intended to legitimise and glorify the emperor's Macedonian dynasty . His son and successor died young; under two soldier-emperors, Nikephoros II ( r.  963–969 ) and John I Tzimiskes ( r.  969–976 ), the Roman army claimed numerous military successes, including the conquest of Cilicia and Antioch , and

24528-399: Was Ruthenia . In Russian, the current name of the country, Россия ( Rossiya ), comes from the Byzantine Greek name for Rus', Ρωσία ( Rosía ). A new form of the name Rus ' , Росия ( Rosiya ), was borrowed from the Greek term and first attested in 1387. The name Rossiia appeared in Russian sources in the late 15th century, but until the end of the 17th century

24696-449: Was elected President of the Russian SFSR. In August 1991, a coup d'état attempt by members of Gorbachev's government, directed against Gorbachev and aimed at preserving the Soviet Union, instead led to the end of the Communist Party of the Soviet Union.

About 1053, Constantine IX disbanded what the historian John Skylitzes calls the "Iberian Army", which consisted of 50,000 men, and it was turned into a contemporary Drungary of the Watch . Two other knowledgeable contemporaries, the former officials Michael Attaleiates and Kekaumenos , agree with Skylitzes that by demobilising these soldiers, Constantine did catastrophic harm to

25200-560: Was captured. Alp Arslan treated him with respect and imposed no harsh terms on the Byzantines. In Constantinople a coup put in power Michael Doukas , who soon faced the opposition of Nikephoros Bryennios and Nikephoros III Botaneiates . By 1081, the Seljuks had expanded their rule over virtually the entire Anatolian plateau from Armenia in the east to Bithynia in the west, and had established their capital at Nicaea , just 90 kilometres (56 miles) from Constantinople. The Komnenian dynasty attained full power under Alexios I in 1081. From

25368-440: Was dissolved by the All-Russian Central Executive Committee . An alternative socialist establishment co-existed, the Petrograd Soviet , wielding power through the democratically elected councils of workers and peasants, called soviets . The rule of the new authorities only aggravated the crisis in the country instead of resolving it, and eventually, the October Revolution , led by Bolshevik leader Vladimir Lenin , overthrew

The Kurgan hypothesis places

25704-449: Was given credit for his predecessor's achievements. Basil I ( r.  867–886 ) continued Michael's policies. His armies campaigned with mixed results in Italy but defeated the Paulicians of Tephrike . His successor Leo VI ( r.  886–912 ) compiled and propagated a huge number of written works.

In an effort to restore Byzantine control over

26208-487: Was invaded annually, Anatolia avoided permanent Arab occupation. The outbreak of the First Fitna in 656 gave Byzantium breathing space, which it used wisely: some order was restored in the Balkans by Constans II ( r.  641–668 ), who began the administrative reorganisation known as the " theme system ", in which troops were allocated to defend specific provinces. With the help of the recently rediscovered Greek fire , Constantine IV ( r.  668–685 ) repelled

26376-450: Was lost to the Umayyad Caliphate , but the empire subsequently stabilised under the Isaurian dynasty. The empire was able to expand once more under the Macedonian dynasty , experiencing a two-century-long renaissance . This came to an end in 1071, with the defeat by the Seljuk Turks at the Battle of Manzikert . Thereafter, periods of civil war and Seljuk incursion resulted in the loss of most of Asia Minor . The empire recovered during

26544-497: Was marked by the theological dispute over Nestorianism , which was eventually deemed heretical , and by the formulation of the Codex Theodosianus law code. It also saw the arrival of Attila 's Huns , who ravaged the Balkans and exacted a massive tribute from the empire; Attila however switched his attention to the rapidly-deteriorating western empire , and his people fractured after his death in 453.

26712-406: Was not esteemed by the "soldier-emperors" who ruled from the frontiers or by the empire's population who, having been granted citizenship , considered themselves "Roman".

27216-412: Was populated by Finno-Ugrian peoples. From the 7th century onwards, the incoming East Slavs slowly assimilated the native Finno-Ugrians.

According to the Primary Chronicle ,

27384-467: Was soon at war on many fronts. The Lombards , fearing the aggressive Avars , conquered much of northern Italy by 572. The Sasanian wars restarted that year, and continued until the emperor Maurice finally emerged victorious in 591; by that time, the Avars and Slavs had repeatedly invaded the Balkans , causing great instability. Maurice campaigned extensively in the region during the 590s, but although he managed to re-establish Byzantine control up to

28056-569: Was triggered by the humiliating failure of the Russo-Japanese War . The uprising was put down, but the government was forced to concede major reforms ( Russian Constitution of 1906 ), including granting freedoms of speech and assembly , the legalisation of political parties, and the creation of an elected legislative body, the State Duma . In 1914, Russia entered World War I in response to Austria-Hungary 's declaration of war on Russia's ally Serbia , and fought across multiple fronts while isolated from its Triple Entente allies. In 1916,

28224-415: Was used adjectivally alongside terms such as "Empire of the Greeks" until the 19th century. It is now the primary term, used to refer to all aspects of the empire; some modern historians believe that, as an originally prejudicial and inaccurate term, it should not be used. As the historiographical periodizations of " Roman history ", " late antiquity ", and "Byzantine history" significantly overlap, there
