موسى الصدر
It was founded by Musa al-Sadr as the "Movement of the Dispossessed" in 1974. The Amal movement gained attention from Shia outcry after the disappearance of Musa al-Sadr and saw a renewal in popularity after Israel's invasion of Lebanon in 1978. The Iranian Revolution of 1978–79 also provided momentum for the party. The Amal Movement is, by a small margin, the largest Shia party in parliament, having sixteen representatives to Hezbollah's thirteen. Amal has an alliance with the Progressive Socialist Party, and with Hezbollah.
