A major seismic event struck beneath the region of Tabriz in northwestern Iran on April 26, 1721. The exact tectonic triggers are not detailed in contemporary records, but the earthquake was of sufficient force to cause catastrophic structural damage across the densely built city.
The earthquake leveled roughly three-quarters of Tabriz, destroying numerous mosques, schools, and historically significant monuments. Casualty estimates vary widely, from 8,000 to 250,000 deaths, with approximately 80,000 considered the most likely figure. The disaster was interpreted by contemporaries as a divine omen or expression of godly wrath.
The destruction severely undermined Tabriz's defensive capacity and economic strength, directly contributing to the Ottoman Empire's successful takeover of the city in 1725. The earthquake also caused lasting economic difficulties for the region and the permanent loss of important historical monuments. Its accounts are frequently confused with the later 1727 Tabriz earthquake.
