Tahmasp I

Who was Tahmasp I?

Tahmasp I was an influential Shah of Iran, who enjoyed the longest reign of any member of the Safavid dynasty. He was the son and successor of Ismail I.

He came to the throne aged ten in 1524 and during his minority was weak and came under the control of the Qizilbash, Turkic tribesmen who formed the backbone of Safavid power. The Qizilbash leaders fought among themselves for the right to be regents over Tahmasp. Upon adulthood, however, Tahmasp was able to reassert the power of the Shah and control the tribesmen.

His reign was marked by foreign threats, primarily from the Ottomans and the Uzbeks. In 1555, however, he regularized relations with the Empire through the Peace of Amasya. This peace lasted for 30 years, until it was broken in the time of Shah Mohammed Khodabanda.

He is also known for the reception he gave to the fugitive Mughal Emperor Humayun which is depicted in a painting on the walls of the Safavid palace of Chehel Sotoon. Humayun's return from Persia, accompanied by a large retinue of Persian noblemen and soldiers, signaled an important change in Mughal court culture, as the Central Asian origins of the dynasty were largely overshadowed by the influences of Persian art, architecture, language and literature.
