Abdelaziz of Morocco (otherwise named Mulai Abd-al-Aziz IV) (1878 - 1943) succeeded his father Hassan I of Morocco as the sultan of Morocco from 1894, at the age of ten until he was deposed in 1908. During his reign Europeans became the main advisors at the court, while local rulers became more and more independent from the sultan. The Algesiras act in 1906 put the country under international protection, guaranteeing the equal economic opportunities of European nations in Morocco, and soon the discovery of phosphate deposits further increased European interest. The sultan was deposed in 1908, but the exercise of Moroccan law and order continued to deteriorate under his successor, Abdelhafid, leading to the humiliating Treaty of Fez in 1912, in which European nations assumed many responsibilities for the sultanate, which was divided in three zones of influence.
