FPM launched the Liberation War against the Syrian Army on 14 March 1989 and participated in all demonstrations against the Syrian occupation until the Cedar Revolution's mass demonstration on 14 March 2005. The Free Patriotic Movement (FPM) split from the March 14 Alliance on 6 February 2006, when its leader Michel Aoun signed a Memorandum of Understanding with Hezbollah. FPM considered its project against the Syrian government completed when the Syrian army left Lebanon at the end of April 2005.
