Islamic Dawa Party
حزب الدعوة الإسلاميةThe Islamic Dawa Party (Hizb al-Da'wa al-Islamiyya) is an Iraqi Shia Islamist political party founded around 1957–1960 in the Shia holy cities of southern Iraq. Established to counter the spread of Marxism and secular ideologies among Iraqi Shia, its leading ideologue was Grand Ayatollah Muhammad Baqir al-Sadr, who wrote the party's manifesto. The party adopted a cell-based organizational structure. It was brutally repressed under Saddam Hussein's Ba'athist regime, particularly after 1979, driving many members into exile in Iran and elsewhere. Abu Mahdi al-Muhandis joined the Dawa Party in 1977 before fleeing to Iran. After 2003, the party became a dominant force in Iraqi politics, with members Nouri al-Maliki and Haider al-Abadi serving as Prime Minister.
