Yunus Emre (Turkish pronunciation: [juˈnus emˈɾe]) (1240?–1321?) was a Turkishpoet and Sufimystic. He has exercised immense influence on Turkish literature, from his own day until the present. Because Yunus Emre is, after Ahmet Yesevi and Sultan Walad, one of the first known poets to have composed works in the spoken Turkish of his own age and region rather than in Persian or Arabic, his diction remains very close to the popular speech of his contemporaries in Central and Western Anatolia. This is also the language of a number of anonymous folk-poets, folk-songs, fairy tales, riddles (tekerlemeler), and proverbs. Like the OghuzBook of Dede Korkut, an older and anonymous Central Asian epic, the Turkish folklore that inspired Yunus Emre in his occasional use of tekerlemeler as a poetic device had been handed down orally to him and his contemporaries. This strictly oral tradition continued for a long while. Following the Mongolian invasion of Anatolia facilitated by the Sultanate of Rûm's defeat at the 1243 Battle of Köse Dağ, Islamic mystic literature thrived in Anatolia, and Yunus Emre became one of its most distinguished poets. Poems of Sultan Yunus Emre — despite being fairly simple on the surface — evidence his skill in describing quite abstruse mystical concepts in a clear way. He remains a popular figure in a number of countries, stretching from Azerbaijan to the Balkans, with seven different and widely dispersed localities disputing the privilege of having his tomb within their boundaries. His poems, written in the tradition of Anatolian folk poetry, mainly concern divine love as well as human destiny:
Yunus durur benim adım
Gün geçtikçe artar odum
İki cihanda maksûdum
Bana seni gerek seni.
Yunus Emre the mystic is my name,
Each passing day fans and rouses my flame,
What I desire in both worlds is the same:
You're the one I need, you're the one I crave.
Yunus Emre's portrait is depicted on the reverse of the Turkish 200 lira banknote issued in 2009.
