Abu Hammu Musa I

Abu Hammu Musa I (died 1318), fourth Zayyanid sultan of Tlemcen and son of Sultan Abu Said Uthman, succeeded his brother Abu Zayyan I in 1308, when the kingdom was exhausted by a long Marinid siege of its capital.

Continuing his brother's work, he pacified restive tribes and re-established control over Bejaia and Constantine. He strengthened the fortifications and halted Marinid expansion near Oujda.

He kept a strong army but cared little for his subjects. His harsh treatment of his son Abu Tashufin proved fatal: in 1318 the prince had him assassinated and seized the throne.
