Answer
Moulay Ahmed ben Mehrez (died 1682) was a Moroccan sultan who briefly claimed the throne of Morocco against Moulay Ismail Ibn Sharif in 1675. Mehrez was a member of the Saadi dynasty, and the son of Moulay Abdellah el-Ghalib. He was governor of the city of Fez when he claimed the throne in 1675. His claim was supported by the French, who were interested in gaining influence in Morocco.
