Kurdish nationalist Xoybûn (Khoyboun) party, Khalil bey Ibn Ibrahim Pacha (Al-Jazira province), Mustafa bey Ibn Shahin (Jarabulus) and Hassan Aouni (Kurd Dagh). There were later in the year, from 30 March to 6 April, "complementary elections". In 1933, France attempted to impose a treaty of independence heavily prejudiced in favor of France. It promised gradual independence but kept the Syrian Mountains under French control. The Syrian head of state at the time was a French puppet, Muhammad 'Ali Bay al-'Abid. Fierce opposition to this treaty was spearheaded by senior nationalist and parliamentarian Hashim al-Atassi, who called for a sixty-day strike in protest. Atassi's political coalition, the National Bloc, mobilized massive popular support for his call. Riots and demonstrations raged, and the economy came to a standstill. After negotiations in March with Damien de Martel, the French High Commissioner in Syria, Hashim al-Atassi went to Paris heading a senior Bloc delegation. The new Popular Front-led French government, formed in June 1936 after the April–May elections, had agreed to recognize the National Bloc as the sole legitimate representatives of the Syrian people and invited al-Atassi to independence negotiations. The resulting treaty called for immediate recognition of Syrian independence as a sovereign republic, with full emancipation granted gradually over a 25-year period. In 1936, the Franco-Syrian Treaty of Independence was signed, a treaty that would not be ratified by the French legislature. However, the treaty allowed Jabal Druze, the Alawite region (now called Latakia), and Alexandretta to be incorporated into the Syrian republic within the following two years. Greater Lebanon (now the Lebanese Republic) was the only state that did not join the Syrian Republic. Hashim al-Atassi, who was Prime Minister during King Faisal's brief reign (1918–1920), was the first president to be elected under a new constitution adopted after the independence treaty. The treaty guaranteed incorporation of previously autonomous Druze and Alawite regions into Greater Syria, but not Lebanon, with which France signed a similar treaty in November. The treaty also promised curtailment of French intervention in Syrian domestic affairs as well as a reduction of French troops, personnel and military bases in Syria. In return, Syria pledged to support France in times of war, including the use of its air space, and to allow France to maintain two military bases on Syrian territory. Other political, economic and cultural provisions were included. Atassi returned to Syria in triumph on 27 September 1936
