From 1902 to 1914, altogether four times Prussian expedition worked great success in Turfan and surrounding areas. Abundant Uigur texts were sent to Berlin and form one of the major groups of the Turfan Collection of the Academy of Sciences of the GDR. Other collections of Uigur texts for Turfan and Dunhuang are in museums, libraries or other inshtutions of boingrad, London, Paris, Stockholm, Helsinki, Istanbul, Ankara, Peking, Urumci, Tokyo, Kyoto, Osaka, and are other places. This paper gives a short survey of editions and studies of the religious texts of Uigur. Nestorian Christianity, Manichaeism, and Buddhism pentrated into the Uigurs at different times. By far most of the Uigur fragments are of Buddhist contents, while Christian and Manichaen texts only few in number.
