In 1970 Air Force General Hafez al-Assad, an Alawite, took power and instigated a "Corrective Movement" in the Ba'ath Party. The coup of 1970 ended the political instability which had existed since independence. Robert D. Kaplan compared Hafez al-Assad's coming to power to "an untouchable becoming maharajah in India or a Jew becoming tsar in Russia—an unprecedented development shocking to the Sunni majority population which had monopolized power for so many centuries". In 1971 al-Assad declared himself president of Syria, a position the constitution at the time permitted only for Sunni Muslims. In 1973 a new constitution was adopted, replacing Islam as the state religion with a mandate that the president's religion be Islam, and protests erupted. In 1974, to satisfy this constitutional requirement, Musa as-Sadr (a leader of the Twelvers of Lebanon and founder of the Amal Movement, who had unsuccessfully sought to unite Lebanese Alawites and Shiites under the Supreme Islamic Shiite Council) issued a fatwa that Alawites were a community of Twelver Shiite Muslims. Under the authoritarian, secular Assad government, religious minorities were tolerated more than before but political dissidents were not. In 1982, when the Muslim Brotherhood mounted an anti-government Islamist insurgency, Hafez Assad staged a military offensive against them known as the Hama massacre.
