The literature of Burma reveals aspects of the Burmese character and their response to modern challenges. Some of the earliest Burmese literature dates back to 1113 AD in the form of dedicatory inscriptions containing poems and prayers. From the 15th to 19th centuries, palm leaf and folded paper literature became common, often focused on Buddhist themes and written by monks and court poets. Modern fiction began with novels in the late 19th century. The founding of the University of Rangoon in 1920 increased literary output and the influence of foreign works like English literature. Burmese literature has become increasingly nationalistic since independence in 1948.
