In 1514, Sultan Selim I marched through Anatolia and reached the plain of Chaldiran near the city of Khoy, where a decisive battle was fought. Most sources agree that the Ottoman army was at least double the size of that of Ismāʻil; however, the Ottomans had the advantage of artillery, which the Safavid army lacked. According to historian Roger Savory, "Salim's plan was to winter at Tabriz and complete the conquest of Persia the following spring. However, a mutiny among his officers who refused to spend the winter at Tabriz forced him to withdraw across territory laid waste by the Safavid forces, eight days later". Although Ismāʻil was defeated and his capital was captured, the Safavid empire survived. The war between the two powers continued under Ismāʻil's son, Emperor Tahmasp I, and the Ottoman Sultan Suleiman the Magnificent, until Shah Abbās retook the area lost to the Ottomans by 1602.
