Franco-Moroccan agreement of 10 September 1844.

The Treaty of Tangier followed the defeat of the Moroccan army at the Battle of Isly by a French force pursuing the Algerian resistance leader Abd al-Qadir, who had frequently sought refuge in Moroccan territory. The treaty obligated the Moroccan government to consider Abd al-Qadir an outlaw and to offer him no assistance.
