مؤتمر الجزيرة الخضراء
France's pre-eminence in Morocco had been upheld by the 1906 Algeciras Conference, following the First Moroccan Crisis of 1905–06. France and Germany agreed on 9 February 1909 that while France would have exclusive political control, the two nations would uphold each other's economic interests in Morocco. In 1911 they forced the sultan to sign a new treaty wherein he promised not to sign any other treaties without French approval, arguably violating the earlier made agreements.
