Evliya Çelebi’s Seyahatname, or Book of Travels, which consists of 10 volumes, is a distinctive account that provides substantial information and details related to almost the entire territory of the Ottoman Empire, including people, architectural structures, literature and languages, religions, history, customs and traditions, geography, food, and the relationships between the Ottoman Empire and other powers. Çelebi wrote Seyahatname in the later years of his life, in 17th century Cairo. Çelebi was raised and received his education at the Ottoman Palace in Istanbul. He had close connections with the Palace through his kinsman, Melek Ahmed Pasha. Çelebi was an Istanbuli gentlemen who spent a lot of time in one of the great centers of the world, Istanbul. The historically-rooted assumption that Yezidis are followers of the second Umayyad Caliph who ordered the killing of Hussain, the grandson of the Prophet Muhammad, in Karbala in 680 shaped how Ottomans treated Yezidis. This perception played an important role in Çelebi’s understanding and representation of the Yezidi community in his writing. Çelebi attempts to show the Yezidi community as one of the main players at the Battle of Karbala through providing different stories about the role of the Yezidi community at the battle. Çelebi formulates his narration in such a way as to make sure that Yezidis were cast as the main perpetrators of the battle who had to be penalized. Çelebi’s account is one of the few sources that offers substantial information on Yezidis from the 17th century. One of the aims of my paper is to investigate the perception of Evliya Çelebi toward one of the lesser-known, non-Muslim Ottoman communities, Yezidis, and to examine what kind of tools and narratives he utilized to justify his hostility against them. I will also explore how we can better understand Yezidis through an examination of Çelebi’s accounts of Yezidis in Seyahatname.
