Mah"di, n. Etym: [Ar., guide, leader.]
Definition: Among Mohammedans, the last imam or leader of the faithful. The
Sunni, the largest sect of the Mohammedans, believe that he is yet to
appear.
Note: The title has been taken by several persons in countries where
Mohammedanism prevails, -- notably by Mohammad Ahmed, who overran the
Egyptian Sudan, and in 1885 captured Khartum, his soldiers killing
General Gordon, an Englishman, who was then the Egyptian governor of
the region.
