Kaikhosro II Jaqeli was the atabeg of the principality of Samtskhe, nominally ruling between 1545–1573. Invested as a puppet ruler by the Ottomans in 1545, Kaikhosro II's further tenure over Samtskhe continued as a hard one, and it was marked by incessant Iranian–Ottoman rivalry, as well as uneasy relations with neighboring Georgian polities, and internecine feuds. He quickly ended up with the western part of his principality being assimilated by the Ottomans and formed into a paşalık, while the eastern part came under Iranian suzerainty. Ottoman actions in the western part eventually made him to directly seek assistance in 1570 from his suzerain, king Tahmasp I (r. 1524–1576) at the Iranian royal court, where he died three years later as well, in 1573.
