This provoked a German reaction, and the "crisis" of 1905-1906 was resolved at the Algeciras Conference in 1906, formalizing France's "special position" and entrusted policing of Morocco jointly to France and Spain. A second "Moroccan crisis", provoked by Berlin, increased European Great Power tensions, and the Treaty of Fez (signed on March 30, 1912) made Morocco a French protectorate. From a strictly legal point of view, the treaty did not deprive Morocco of its status as a sovereign state.
