Iskandar Beg Munshi, an Iranian historian of the first half of the 17th century, noted that Luarsab was distinguished among Georgian kings for his courage, refusing to show obedience and pay tribute. Only Luarsab continued to fight against the Iranians as other Georgian kings had made deals and accepted Iranian sovereignty, often accepting Islam and taking Persian names and embracing Persian culture for many centuries afterwards (Such as the important Georgian kings Isa Khan, Gurgin Khan, Daud Khan, Rostam Khan, Semayun Khan and many others). In 1540-1554 Shah Tahmasp led four campaigns against Georgia, devastating the country's eastern and southern regions and taking tens of thousands of Georgian captives to Iran.
