What happened
In July 1501, the young Ismail entered Tabriz, capital of the Shirvanshah territory, and declared himself shah of all Iran, founding the Safavid dynasty. One of his first acts as ruler was to declare Twelver Shi'ism the official state religion of his new empire. At the time, most of Iran's population was Sunni, and Ismail hoped that a distinct Shia identity would unify his Iranian subjects and set them apart from his Sunni rivals, the Ottomans to the west and the Uzbeks to the east. The Ottomans answered Safavid expansion in kind: Sultan Selim I invaded Iranian Azerbaijan and sacked Tabriz in 1514, a defeat at the Battle of Chaldiran that shook Ismail's standing among his own followers.
Why it matters
Ismail's decision to impose Twelver Shi'ism turned a religious minority into Iran's official faith and, over the following centuries, into the majority religion practiced by most Iranians today, a transformation with no real precedent in the region's earlier Islamic history. It also hardened a sectarian and political divide between Safavid Iran and the Sunni Ottoman Empire that shaped Middle Eastern politics for the next two centuries.
How we know
Ismail's conquest of Tabriz and his religious decree are documented in contemporary Safavid court chronicles and corroborated by Ottoman records of the subsequent wars, including detailed Ottoman accounts of the 1514 Chaldiran campaign.
