Don Cossacks
Don Cossacks (Russian: Донские казаки, romanized: Donskiye kazaki, Ukrainian: Донські козаки, romanized: Donski kozaky) or Donians (Russian: донцы, romanized: dontsy, Ukrainian: донці, romanized: dontsi), are Cossacks who settled along the middle and lower Don. Historically, they lived within the former Don Cossack Host (Russian: Донское казачье войско, romanized: Donskoe kazache voysko, Ukrainian: Головне Донське військо, romanized: Holovne Dons'ke viis'ko), which was either an independent or an autonomous democratic polity in present-day Southern Russia and parts of the Donbas region of Ukraine, from the end of the 16th century until 1918.
