Abbas the Great or Abbas I of Persia (Persian: شاه عباس کبیر‎; 27 January 1571 – 19 January 1629) was the 5th Safavid Shah (king) of Iran, and is generally considered as one of the greatest rulers of Iranian history and the Safavid dynasty. He was the third son of Shah Mohammad Khodabanda. Abbas was a great builder and moved his kingdom's capital from Qazvin to Isfahan, making the city the pinnacle of Safavid architecture. In his later years, following a court intrigue involving several leading Circassians, Abbas became suspicious of his own sons and had them killed or blinded.
