Ascendancy 1975–76 When the
Lebanese Civil War broke out in April 1975, as a member of the LNM and later at the 'Spring Offensive' held against
East Beirut and
Mount Lebanon in March 1976. They also took part on January 20 of that same year in the violent (and controversial) sieges of the Christian towns of Es-Saadiyat,
Damour, and
Jiyeh in the
Iqlim al-Kharrub, on the side of PLO and
Palestine Liberation Army (PLA) units to avenge the earlier
Tel al-Zaatar massacre by the
Lebanese Front militias.
Reversals 1976–82 The
Syrian military intervention of June 1976 – which the INM/al-Mourabitoun initially strongly opposed, even fighting the
Syrian Army at the
Battle of Bhamdoun in the
Aley District, but gradually came to terms with it – and the slow decline of the Movement's political role at the beginning of the 1980s, caused their influence within the
Sunni community to wane, losing in the end its final base of support amongst the political and intellectual elites. Towards the end of the 1970s heavy casualties and their involvement in atrocities against non-Muslims caused the number of militants from other sects in the ranks to drop sharply, a situation further aggrieved by internal splits that occurred at the early 1980s. This led a significant number of prominent
Sunnis – such as the jurist
Walid Eido and the activist Samir Sabbagh – to leave the INM leadership board to set up their own organizations, and thereby the Movement became an exclusively Sunni Muslim force. Relations with its Lebanese coalition partners were also strained to the point of the al-Mourabitoun battling rival Nasserite parties such as the
Nasserite Correctionist Movement (NCM) in November 1975 over control of the
Karantina district in East Beirut, later fighting the
Syrian Social Nationalist Party (SSNP) factions in 1980–81 for the possession of certain West Beirut quarters. Nevertheless, the al-Mourabitoun did not lost its military capabilities, and during the
June 1982 Israeli invasion of Lebanon, they helped the PLO in the defense of the southwestern outskirts of the Lebanese Capital from
IDF attacks until the end of the siege in September of that year. The 1982 Israeli Judicial inquiry into
events in Beirut estimated that the strength of the al-Mourabitoun in West Beirut was 7,000 fighters.
Decline and demise 1983–88 On January 29, 1983, the Israeli-run
Front for the Liberation of Lebanon from Foreigners (FLLF) detonated a car-bomb close to the
Fatah HQ at
Chtaura, and another in West Beirut, close to the HQ of the INM/al-Mourabitoun. Some sixty people were killed and hundreds wounded. Ibrahim Kulaylat emerged from the wreck of the LNM and the Palestinian withdrawal as the dominant Sunni leader, though he opted not to join the LNRF/
Jammoul nor the pro-Syrian LNSF alliances in the mid-1980s, and consequently the political influence of the INM/al-Murabitoun had waned significantly. The Movement initially waged its own guerrilla war at the Beirut area against Israeli forces, but later fought in a more conventional fashion at the 1983–84
Mountain War allied with the
Druze PSP/PLA, the LCP/Popular Guard and SSNP in the
Chouf District against the Christian
Lebanese Forces (LF) and the Lebanese Army. This alliance was short-lived, however, and in March 1985, the Druze PSP/PLA stormed and seized the Al-Mourabitoun facilities in West Beirut, including their Party' Headquarters and their radio and television studios. When the
War of the Camps broke out in April that year at West Beirut, it saw the Al-Mourabitoun allied with the PLO, the Nasserite
Sixth of February Movement, the
Communist Action Organization in Lebanon (OCAL), and the
Kurdish Democratic Party – Lebanon (KDP-L) pitted against a powerful coalition of Shia
Amal movement, pro-Syrian
SSNP-L, the
Lebanese Army, and anti-
Arafat dissident Palestinian guerrilla factions of the
Palestinian National Salvation Front backed by
Syria. Eventually, the al-Murabitoun was crushed after a week of brutal fighting, and ceased to exist as a significant fighting force. Following its defeat, the movement lost many of its Shia foot-soldiers and members, becoming an almost exclusively
Sunni Muslim militia. Deprived from its own military wing, the weakened INM went underground again for the remainder of the war and gradually withered away, forcing Ibrahim Kulaylat to flee the Country in 1986 to seek asylum in
Switzerland. Some remnants of the Al-Mourabitoun, however, remained at large in West Beirut, waging a fierce guerrilla war against the
Syrian Army until February 1987, only to be brutally suppressed in the 1987–88 anti-militia sweeps carried out jointly by
Syrian Commando troops and the Lebanese
Internal Security Forces (ISF).
The post-war years After a long period of inactivity throughout the 1990s, the INM finally returned to the spotlight in April 2001, when they announced in a press conference held in Beirut their official comeback to Lebanese domestic politics. In 2006 it re-opened offices in Beirut, the North (
Tripoli and the
Akkar), the
Beqaa Valley and the South (
Jabal Amel). The movement is still headed by Ibrahim Kulaylat. ==Uniforms and insignia==
