Yunus Emre, who influenced Turkish literature, culture and philosophy of life deeply, was a Turcoman dervish who lived in last quarter of the thirteenth century and the early part of the fourteenth century. This period touches on the end of the Seljuk Period and the foundation of the Ottoman Empire. Many cities were established at that time, and many became scientific and cultural centres in the Anatolian Seljuk Period. However, the Mongolian invasion and the subsequent depravations dragged the people of Anatolia into poverty and despair. This difficult period was overcome through the collective efforts ofsufistic leaders such as Mevlana, Hacı Bektaşl-i Veli and Hacı Bayram Veli. Yunus Emre was born in Sarıköy (today's Yunus Emre town) located between Mihalıççık and Sivrihisar in 1240. He used various pseudonyms, such as Aşık Yunus (Yunus the Lover), Biçare Yunus (Poor Yunus), koca Yunus (aged Yunus), Dervish Yunus, Yunus Emrem and Miskin Yunus (Yunus the Miserable). As inferred from his poems, he received his education in Konya. He knew the Arabic and Persian Languages, valid languages of his period, and Islamic sciences well.
