Johannes Avetaranian (born Muhammad Shukri Effendi) (30 June 1861-11 December 1919) was a Turkish descendent of Muhammad who later became a Christian missionary. While a mullah in Turkey, he converted to Christianity, and later became a missionary to Eastern Turkestan (present day Xinjiang, China. He translated the New Testament into the Uyghur language
In his biography "A Muslim Who Became a Christian", Aveteranian claimed to have been unaware of his descent from the Islamic prophet, Muhammad, until his trip to Erzurum. During the trip, Aveteranian and his father had put on the Green turbans, to which only the Sayyids or descendants of Muhammad are entitled. Prior to this, he had only worn this once in his childhood. The Green turban had been a gift which was presented to him by his maternal aunt. A local Mullah was astonished to see the green turban, and inquired as to from where he had obtained it. Then he requested Aveteranian to ask whether his aunt was aware that only Sayyids were entitled to wear green turbans. He did so, and the next day, his aunt went to the Mullah and clarified the Mullah's doubts as to their descent when she revealed her father's name. After this incident, Aveteranian gained respect from the Mullah, who would always defer to him, while in Aveteranian's presence.
He left Kashgar in 1897, thinking that he would soon return, but that did not work out. Instead he worked with the German Orient Mission in Bulgaria, where he started a Christian newspaper, Gunesh, in Turkish. The newspaper was circulated in Turkey proper.
