After the Persian shah Abbas I promised peace in return for Luarsab's surrender, the young king agreed with the hope of saving his kingdom from complete destruction.

When Shah Abbas I succeeded in driving the Ottoman armies out of eastern Georgia, leaving a Persian force in Tbilisi, he confirmed Luarsab as king of Kartli.

The Ottomans attempted to remove Luarsab, sending a large army to Georgia, which was destroyed by the Georgian general Giorgi Saakadze at the Battle of Tashiskari in 1609.

The great nobles of the realm led by Shadiman Baratashvili convinced the king that Saakadze was a Persian agent seeking a royal crown.

[citation needed] In 1612, Luarsab had Mohammad Khan assassinated[1] and allied with another Georgian monarch, Teimuraz I of Kakheti, to counter an anticipated Persian aggression.
