What happened
In 1598, Shah Abbas I moved the Safavid capital from Qazvin to Isfahan on the central Iranian plateau, deliberately positioning it away from the shifting Ottoman and Uzbek frontiers and closer to Persian Gulf trade routes newly reached by British and Dutch merchants. Abbas rebuilt Isfahan around the vast Naqsh-e Jahan square, ringed with the Shah Mosque and other monumental buildings, and under his rule the Safavid state reached the height of its military, political, and economic power. Muslim, Christian, Jewish, and Zoroastrian communities and foreign merchants from across Europe and Asia mixed in the city's markets, giving rise to a saying repeated by Isfahan's own residents: Isfahan Nesf-e Jahan, Isfahan is half the world.
Why it matters
Abbas's Isfahan demonstrated that Safavid Iran could build a capital meant to rival any city in Europe or Asia for splendor and cosmopolitan reach, cementing the dynasty's reputation as a major early modern power rather than a regional also-ran squeezed between Ottoman and Uzbek neighbors. The Naqsh-e Jahan square and its surrounding monuments survive today as a UNESCO World Heritage Site and remain the clearest physical record of Safavid ambition.
How we know
Isfahan's Safavid-era architecture survives largely intact and has been studied extensively by architectural historians, while foreign travelers' accounts from the 17th century, including English and Dutch merchants who visited the city, independently corroborate its cosmopolitan reputation.
