Hummay (Umme, Houmé or Hume) was the first Muslim king, mai, of the Sefuwa dynasty within Kanem-Bornu Empire from 1085 to 1097, replacing the Sefuwa-Duguwa dynasty. The dynasty founded by him was to survive until 1846. His rule had important consequences because of the spread of Islam during his reign. This provoked some dissension, causing the Zaghawa to break from the empire and move east.
