Teimuraz I of Kakheti
Kaikhosro was a son of Vakhtang I, and a younger brother of Teimuraz I, on whose death at the battle of Marabda against Safavid Iran he succeeded to the fief of Mukhrani in 1625. Kaikhosro was allied with the warlord Giorgi Saakadze, who helped him to become regent of Kartli during the anti-Iranian rebellion to the chagrin of his rival Zurab, Duke of Aragvi. Zurab, suspicious of the tandem's designs and inclined to believe that his brother Giorgi, who was married to Kaikhosro's daughter, was part of a plot against him, had Giorgi blinded and made an alliance with Teimuraz I of Kakheti, whom Saakadze tried to prevent from acceding to the throne of Kartli.
