Azov Siege Seat Festival in Azov
A historical event and likely reenactment tied to the Azov Siege Seat of 1637-1642, when Don and Zaporizhian Cossacks held the captured Ottoman fortress of Azov against Turkish forces.
Not verified as a formally named annual public festival under this exact title, but grounded in one of the best-documented episodes in southern Russian Cossack history.
