The first translation activites among the Turks are seen in Uighurs whohad changed their religion. The major part of the Uighur corpus oftranslations is known to consist of religion based works. That the contents ofthe works were religious, was a necessity for a community which hadchanged its religion and wished to understand the new environment andperform the rules of the religion they accepted. The first known translationsof Muslim Turks are the translations of the holy book, the Qur an, which wasan outcome of the same necessity. The first translations of the Qur an inTurkish, were made in interlinear method, under the original Arabic text, inthe eastern Turkish of 13.-14. centuries. Various studies have been made inTurkey and abroad on the copies of TIEM 73, Rylands, Uzbekistan andSüleymaniye which are the interlinear translations of Qur an s EasternTurkish version.
