In mid-1926, Italy set out to extend its political influence in Albania, asking Tirana to recognize Rome's special interest in Albania and accept Italian instructors in the army and police. Zogu resisted until an uprising in the northern mountains pressured the Albanian leader to conclude the First Treaty of Tirana with the Italians on November 27, 1926. In the treaty, both states agreed not to conclude any agreements with any other states prejudicial to their mutual interests.
