Sultan Yavuz Selim I
Selim's nickname was Yavuz, standing in Turkish for "the Stern" or "the Grim". During his rule, the Ottoman Empire reached huge extensions thanks to his conquests especially in the Middle East. He also took the title of being a Caliphate from Abbasids after defeating Mamluk state in Egypt, becoming the leader of the Islamic world as well. The sword, teeth and the mantle of Prophet Muhammad were taken from Cairo to Istanbul, which are kept today in Topkapi Palace Museum.
Selim was one of the Empire's most successful and respected sultans. He was tall, strong, brave, fierce, but very modest despite his powers and was writing poems. He never rested during his rule, he worked hard and organized campaigns, filled the treasury with lots of gold. He was an expert on using the sword, archery, and wrestling. He had long mustache but he cut his beard, unlike other sultans. He also had an earing on one ear.
In 1514, before his campaign to Iran, Yavuz Selim I ordered the persecution of thousands of Alevis in the province of Rum in Anatolia in order to avoid the risk of being attacked while marching to that territory for the war.
