The Cossacks are a predominantly East Slavic Orthodox 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 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 the military duty to serve in the irregular troops (mostly cavalry). 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 the Dnieper, Don, Terek, and Ural river basins, and played an important role in the historical and cultural development of both Ukraine and parts of Russia.
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 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 in the Soviet Army, and many of the Cossack traditions were suppressed during the years of rule under Joseph Stalin and his successors. During the Perestroika era in the Soviet Union in the late 1980s, descendants of Cossacks moved to revive their national traditions. In 1988, the Soviet Union passed a law allowing the re-establishment of former Cossack hosts and the formation of new ones. During the 1990s, many regional authorities agreed to hand over some local administrative and policing duties to their Cossack hosts.
Between 3.5 and 5 million people associate themselves with the Cossack cultural identity across the world even though the majority, especially in the Russian Federation, have little to no connection to the original Cossack people because cultural ideals, legacy, and genomes changed greatly with time. Cossack organizations operate in Russia, Ukraine, Belarus, Kazakhstan, Canada, and the United States.
Etymology
Max Vasmer's etymological dictionary traces the name to the Old East Slavic word , , a loanword from Cuman, 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.
History
Early history
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 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 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 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.
