How a brilliant general turned a failing empire into a regional superpower
The Ottoman–Persian War of 1730–1735 was a transformative struggle that reshaped the map of the Caucasus. Driven by the military genius of Nader, the conflict saw the resurgence of the Iranian Empire, the collapse of the Safavid dynasty, and the eventual rise of the Afsharid era through sheer tactical dominance.
The conflict began when the Ottoman Empire refused to relinquish western Iranian territories previously held under the Hotak dynasty. Nader, a talented Safavid general, issued an ultimatum for their withdrawal. When the Ottomans ignored this, a five-year struggle ensued. Early in the war, Nader was forced to pause his momentum to suppress a rebellion by the Abdali Afghans, who besieged Mashhad for fourteen months, distracting him from his primary objective against the Ottomans.
Internal politics further complicated the war effort. While Nader was occupied in the east, Shah Tahmasp launched an ill-fated campaign to recapture Yerevan, ultimately losing significant territory and signing a treaty that ceded Georgia and Armenia to the Ottomans. Nader, viewing this as a betrayal, orchestrated the Shah's abdication in 1732, installing the infant Abbas III as a figurehead while he assumed the role of regent. This consolidation of power allowed Nader to pursue a more aggressive military strategy, though he initially suffered a major defeat against the Ottoman general Topal Osman Pasha in 1733.
Nader eventually regained the initiative by defeating and killing Topal Osman Pasha, subsequently securing a strategic alliance with Russia. This partnership, solidified by a 1735 treaty in Ganja, ensured Russian withdrawal from Persian lands. The war reached its climax at the Battle of Yeghevard, where Nader’s forces crushed a superior Ottoman army. By the summer of 1735, Armenia and Georgia were reclaimed, and the Ottomans were forced to recognize Iranian hegemony. This victory cemented Nader's prestige, enabling him to overthrow the Safavids and establish the Afsharid dynasty, setting the stage for his later campaigns in India.
