Vakhtang left him in charge of the government of Kartli (eastern Georgia) during his absence at the Safavid court of Persia from September 1716 to August 1719.

His position was recognized by the Shah of Persia who invested him, in 1717, with the title of janishin, a crown, sword, gold insignia, and robe of honor.

[2] When the Ottoman armies invaded Georgia in 1723, Bakar attempted to negotiate, but eventually followed his father in a Russian exile in July 1724.

He permanently settled in Moscow where he came to be known as Tsarevich Bakar Vakhtangovich Gruzinsky (Russian: Бакар Вахтангович Грузинский).

Bakar was married to Ana, daughter of Giorgi, Duke of Aragvi (1706 – 18 February 1780), who accompanied him in Russia and died in Moscow, being buried in the Donskoy Monastery.
