The first written information about the Kyrgyz is found in ancient Chinese chronicles. However, no Kyrgyz historian who wrote a history of the nation can be identified before the end of the 19th century. Of course, there were many relaters of genealogical legends and stories based mainly on folk heritage. This paucity of indigenous historiography is the reason that Kyrgyz history has been written mainly from external sources in various languages, including Chinese, Arabic, Iranian, Greek, Turkic, Mongolian, and Russian. Kyrgyz historians made their first attempts at publishing histories at the beginning of the 20th century under the influence of the reformist movement known as Jadidism. Some Kyrgyz intellectuals brought out works in Kazan, Ufa, and Orenburg. For example, books by Osmonaaly Sydyk uulu were published in Ufa in 1913 and 1915.
