The Regency of Algiers was a largely independent tributary state of the Ottoman Empire during the early modern period, located on the Barbary Coast of North Africa from 1516 to 1830.

Bugeaud, attempting to complete the French conquest of Algeria, instigated the battle without a declaration of war in order to force negotiations concerning Moroccan support for the Algerian resistance leader Abd el-Kader to conclude on terms favorable to the French who demanded the Sultan of Morocco to withdraw support for Abd el-Kader.
