The Fatah Alliance (Arabic: ائتلاف الفتح, romanized: iʾtilāf al-fatḥ), also sometimes translated as the Conquest Alliance, is a political coalition in Iraq formed to contest the 2018 general election. The main components are groups involved in the Popular Mobilization Forces which is mainly a state-sponsored umbrella organization made up of Iraqi Shiite Muslims who fought from 2014 to 2017 alongside the Iraqi Army to defeat ISIL. It is led by Hadi Al-Amiri, the leader of the Badr Organization.^[6][7][8][9]

The Fatah Alliance included the Badr Organisation, the Al-Sadiqoun Bloc (the political wing of Asa'ib Ahl al-Haq, AAH), Kata'ib Hezbollah and Kata'ib al-Imam Ali, all key components of the Hashd. The Fatah Alliance agreed to run jointly with al-Abadi's Nasr al-Iraq (Victory of Iraq) list, but the agreement fell apart after only 24 hours, reportedly over Abadi's conditions.^[10][11] The Badr Organisation, headed by Hadi Al-Amiri, was previously part of the ruling State of Law Coalition and announced their withdrawal from the Alliance in December 2017,^[12][6] and won 22 seats.

Asa'ib Ahl al-Haq split from the Sadrist Movement in 2004.^[13] It has also been one of the main Iraqi armed groups active in the Syrian Civil War.^[14][15] They have received funding and training from Iran's Quds Force^[16][17] and, like many Sadrists, are reported to have religious allegiance to the Iranian Grand Ayatollah Kazem al-Haeri.^[18] AAH formed a political wing, called the Al-Sadiqoun Bloc, to contest the 2014 Iraqi parliamentary election, winning one seat.
