Battle of Chaldiran
The Battle of Chaldiran (23 August 1514) was fought between the Ottoman Empire of Selim I and the Safavids in  the area of Chaldiran in the eastern Anatolian plateau. The Ottomans won and sp the Ottomans took eastern Anatolia and northern Iraq from the Safavids. The loss of Anatolia was a turning point for Safavid history. One feature of the battle was that the Ottomans used guns and cannons to defeat the cavalry corps. However, the Ottomans led more than twice as many troops as the Safavids, and it said that the difference in troop strength made the difference between victory and defeat. The defeat of the Safavids in the battle destroyed the myth of Islam I's supremacy and had historical significance by switching of the Kurds from belonging the Safavids to belonging to the Ottomans. Kurdish sheikhs, who had initially accepted Safavid suzerainty, recognized that the power of the Safavid dynasty had begun to wane since Ismail's defeat at Chaldiran and began to assert their independence. Then, Selim I won the loyalty of the Ottomans by providing financial and military support to the Kurdish sheikhs.
