## Who they were

Ismail I (1487–1524, r. 1501–24) was the founder of the Safavid dynasty. He was born the hereditary head of the Safaviyya Sufi order of Ardabil, which had turned militant and messianic under his forebears.

## What they did

At fourteen, backed by Turkoman Qizilbash cavalry who according to the sources revered him as a semi-divine figure, he took Tabriz in 1501 and proclaimed himself shah; within a decade he ruled all Iran. His defining act was to proclaim Twelver Shia Islam the state religion and enforce it, importing Shia scholars and suppressing Sunni practice — the conversion of the mostly Sunni population took generations. He was also a poet, writing Turkic verse under the pen name Khatai, works still sung in the Azerbaijani tradition. In 1514 Ottoman firearms crushed his army at Chaldiran; Tabriz was briefly lost and his aura of invincibility broken. By the standard account he never again led an army and withdrew from public life in his last decade.

## Legacy

He founded the state that made Iran Shia, an act that ranks among the most consequential religious-political deeds in the region's history. He died in 1524 and was succeeded by his son Tahmasp I.
