The Georgian–Seljuk wars, also known as Georgian Crusade, is a long series of battles and military clashes that took place from 1064 until 1213, between the Kingdom of Georgia and the different Seljukid states that occupied most of South Caucasus. The conflict is preceded by deadly raids in the Caucasus by the Turks in the 11th century, known in Georgian historiography as the Great Turkish Invasion.
