The war was triggered by territorial disputes between the two empires, especially when the Bey of Bitlis decided to put himself under Persian protection.^[10] Also, Tahmasp had the governor of Baghdad, a sympathiser of Suleiman, assassinated.

On the diplomatic front, the Safavids had been engaged in discussions with the Habsburgs for the formation of a Habsburg–Persian alliance that would attack the Ottoman Empire on two fronts.^[10]

The Ottomans, first under the Grand Vizier Ibrahim Pasha, and later joined by Suleiman himself, successfully attacked Safavid Iraq, recaptured Bitlis, and proceeded to capture Tabriz and then Baghdad in 1534.^[10] Tahmasp remained elusive as he kept retreating ahead of the Ottoman troops, adopting a scorched earth strategy.

Under the Grand Vizier Rüstem Pasha, Ottomans attempting to defeat the Shah once and for all, Suleiman embarked upon a second campaign in 1548–1549. Again, Tahmasp adopted a scorched earth policy, laying waste to Armenia. Meanwhile, the French king Francis I, enemy of the Habsburgs, and Suleiman the Magnificent were moving forward in a Franco-Ottoman alliance, formalized in 1536, that would counterbalance the Habsburg threat. In 1547, when Suleiman attacked Persia, France sent its ambassador Gabriel de Luetz, to accompany him in his campaign.^[11] Gabriel de Luetz gave military advice to Suleiman, as when he advised on artillery placement during the Siege of Van.^[11] Suleiman made gains in Tabriz, Persian ruled Armenia, secured a lasting presence in the province of Van in Eastern Anatolia, and took some forts in Georgia.

In 1553 the Ottomans, first under the Grand Vizier Rüstem Pasha, and later joined by Suleiman himself, began his third and final campaign against the Shah, in which he first lost and then regained Erzurum. Ottoman territorial gains were secured by the Peace of Amasya in 1555. Suleiman returned Tabriz, but kept Baghdad, lower Mesopotamia, western Armenia, western Georgia, the mouths of the Euphrates and Tigris, and part of the Persian Gulf coast. Persia retained the rest of all its northwestern territories in the Caucasus.

Due to his heavy commitment in Persia, Suleiman was only able to send limited naval support to France in the Franco-Ottoman invasion of Corsica (1553).
