The chronicle of king Bäkaffa (r.1721-1730) is an important genre in Ethiopian historiography. Originally it was composed by Azzaž Sinoda and Kǝnfä Michael in the first half of 18th century. There are three copied chronicles of Bäkaffa that are collected for making critical edition. These chronicles are kept in Ethiopia (NALA) and European libraries. Ms-B (Bodl. Aeth. 32) is dated as the 18th century; A (Eth. 167) belongs to the 19th century; and NL (NL.513) to the 20th century.
