Muwahhid Abdul Yusuf (Yarmuk)

Muwahhid Abdul Yusuf, later to be the first Grand Sheikh of the Almohad kingdom, was a strong willed, though bad tempered, character to whom the collapse of the Almoravid Empire can be almost entirely attributed. His short rule enabled him to lay the foundations for a strong Algerian state, which was brought to greatness by his successors of the Muwahhid Dynasty.
