Georgian-Seljuk wars: At the Battle of Basian the Kingdom of Georgia defeats the Sultanate of Rum.
The Battle of Basiani was fought, in the 13th century, between the armies of the Kingdom of Georgia and the Seljuqid Sultanate of Rum in the Basiani valley, 60 km northeast of the city of Erzurum in what is now northeast Republic of Turkey. The battle is variously dated between 1202 and 1205, but 1203 or 1204 has lately been given preference. The contemporary Muslim chronicler Ibn Bibi places the battle in 598 AH (October 1, 1201 September 19, 1202). The modern Turkish historians identify the castle of Micingerd (Mazankert) as the location of the battle.
Georgian–Seljuk wars (Georgian: ქართულ-სელჩუკური ომები, romanized: kartul-selchuk'uri omebi), also known as Georgian Crusade, is a long series of battles and military clashes that took place from c. 1048 until 1213, between the Kingdom of Georgia and the different Seljuqid states that occupied most of Transcaucasia. 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.
