Al-Mourabitoun

Initially, the Movement of Independent Nasserists was the name of the political organization, whilst "al-Murabitoun" designated their militia forces. However, this distinction between political and military wings became blurred over time (and the militia has been subsequently abolished), "the Sentinels", but also meaning "Guardians" or "Saviours" – carries historical Islamic connotations (see Almoravids).

Founded in 1957 at Beirut by a group of Lebanese Nasserite activists led by Ibrahim Kulaylat who opposed the pro-Western policies of President Camille Chamoun, the INM came to prominence at the height of the 1958 Civil War. The Movement’s own 2,000-strong militia, ‘The Sentinels’ (Arabic: Al-Murabitun, al-murabitûn or al-Mourabitoun), clashed with the Lebanese Army and pro-government Christian militias in northern Lebanon and Beirut.{{cite web|url=http://www.country-data.com/cgi-bin/query/r-8042.html|title=Lebanon - Independent Nasserite Movement|website=www.country-data.com|access-date=24 April 2018|url-status=live|archive-url=https://web.archive.org/web/20171012085732/http://www.country-data.com/cgi-bin/query/r-8042.html|archive-date=12 October 2017}}

Despite experiencing a temporary decline in the years immediately after the 1958 crisis, the INM remained an active force in Lebanese politics throughout the 1960s and 1970s. At the beginning of the 1970s, the Movement re-emerged as a major political faction within the Sunni Muslim community, forging alliances with other anti-establishment leftist parties such as the Progressive Socialist Party (PSP) led by Kamal Jumblatt and the Lebanese Communist Party (LCP). In 1969 the INM became a member of the "Front for Progressive Parties and National Forces" (FPPNF), later reorganized in 1972 as the Lebanese National Movement (LNM). Consistent with its Pan-Arab ideals, the radical INM was a staunch advocate of the Palestinian cause in Lebanon since the late 1960s, cultivating close political and military ties with the Palestine Liberation Organization (PLO) in the immediate pre-war years.

As its name implies, the INM espoused the ideals of the late Egyptian President, Gamal Abdel Nasser, a blend of Socialism and secular pan-Arab nationalism, expressed on his party slogan 'Freedom – Unity – Socialism' (Arabic: الحرية - الوحدة - الاشتراكية | al-Hurriyat – al-Wahdat – al-Aishtirakia).

Being radically opposed to the Christian Maronite-dominated political order in Lebanon, the political goals of al-Murabitoun were to preserve the Arab and secular character of Lebanon and, in the long-term, establish a socialist political and economic system.Mroueh Kerim; Sabbagh Samir. [https://www.jstor.org/stable/3010991 "Lebanon is Where the US and Israel will Settle Accounts with the Palestinians"] {{webarchive|url=https://web.archive.org/web/20170214175941/http://www.jstor.org/stable/3010991 |date=2017-02-14 }} in MERIP Reports, No. 77. (May 1979), pp. 12-15+26.

The INM presented itself as being pragmatic in ideological terms however, and that its doctrine was based upon a fusion between materialist Marxist and liberal idealist theories.Hafez, Ziad. "[https://www.jstor.org/stable/3011238 Independent Nasserite Movement: Interview with Ziad Hafez] {{webarchive|url=https://web.archive.org/web/20170214175849/http://www.jstor.org/stable/3011238 |date=2017-02-14 }}" in MERIP Reports, No. 61. (October, 1977), pp. 9–14. In 1979, leading party cadre Samir Sabbagh described the INM as particularly close to the Lebanese Communist Party (LCP).

Although the INM claimed to be a secular, non-sectarian movement, its membership has always been overwhelmingly Muslim, being perceived within Lebanon as a predominantly Sunni organization. During the Movement's resurgence in the early 1970s, it drew its support largely from working class’ and impoverished petty bourgeoisie Sunnis,Barbee, Lynne. [https://www.jstor.org/stable/3011235 Interviews with the Lebanese National Movement: Introduction] {{webarchive|url=https://web.archive.org/web/20170214181736/http://www.jstor.org/stable/3011235 |date=2017-02-14 }} in MERIP Reports, No. 61. (October, 1977), pp. 3-5. but this did not prevent them of attracting followers from other sects. Indeed, a 1987 report used by the U.S. Library of Congress study on Lebanon estimated the INM membership since the mid-1970s to be about 45% Sunni, 45% Shia and 10% Druze, although other unconfirmed sources present the remaining 40% as Christians. Geographically, the movement had its epicentre in the Sunni areas of Beirut.

Quietly re-formed in early 1975, their "Sentinels" militia, now known as the Al-Mourabitoun Forces (Arabic: قوات المرابطون | Quwwat al-Murabitun), started with just 150–200 poorly armed militants,El-Kazen, The Breakdown of the State in Lebanon (2000), p. 303. but it subsequently grew to 3,000–5,000 men and women drawn from the Muslim quarters of West Beirut placed under the command of Kulaylat himself.McGowan, Roberts, Abu Khalil, and Scott Mason, Lebanon: a country study (1989), pp. 242-243.Makdisi and Sadaka, The Lebanese Civil War, 1975-1990 (2003), p. 44, Table 1: War Period Militias. Headquartered at the Tarik al-Jadida quarter of the Corniche El-Mazraa commercial district in West Beirut, the INM/al-Mourabitoun in the early 1980s numbered some 1,000 regular fighters and 2,000 reservists secretly trained by the Palestinian factions (Fatah,[https://www.jstor.org/stable/2536041 Documents and Source Material: Arab Documents on Palestine and the Arab-Israeli Conflict] {{webarchive|url=https://web.archive.org/web/20170312053451/http://www.jstor.org/stable/2536041 |date=2017-03-12 }} in Journal of Palestine Studies, Vol. 5, No. 3/4.

Since its foundation the militia quickly attained a 'regular' outlook, attested by the high discipline and organization of its 3,000 uniformed militiamen into conventional branches of Armor, Infantry and Artillery, backed by Medical, Signals and Military Police support units. Whilst Druze, Sunni and Shia Muslims filled the rank-and-file, its officer corps was staffed mostly by Sunnis and a few Christians trained in Libya and Iraq.El-Assad, Civil Wars Volume 1: The Gun Trucks (2008), p. 7.

Stubborn and determined fighters, adept at employing guerrilla tactics in urban areas, the INM/al-Mourabitoun operated mainly within West Beirut, controlling by the mid-1980s the important Mahallat Abu Shaker, Wadi Abu Jamil, Hamra, Corniche El-Mazraa, Corniche El-Manara, Bashoura, Basta El-Tahta, Chyah and Ras Beirut districts and quarters. They also operated two clandestine ports located at Ouza'i district and at the Ain El-Mreisseh waterfront sector of the Lebanese capital, which were used primarily for arms-smuggling in collusion with the Sidon-based Popular Nasserist Organization (PNO).Traboulsi, Identités et solidarités croisées dans les conflits du Liban contemporain; Chapitre 12: L'économie politique des milices: le phénomène mafieux (2007), parte III. A third illegal port located at the Karantina dock area in East Beirut was briefly held by the INM since November 1975, until being forced out by the Christian militias on January 18, 1976.O'Ballance, Civil War in Lebanon (1998), p. 43.

Like other Lebanese factions, the INM operated its own media services. A radio station was set up in 1975, the "Voice of Arab Lebanon" (Arabic: Iza'at Sawt Lubnan al-Arabi), followed in 1982 by a television station, the "Television of Arab Lebanon" (Arabic: Televizyon Lubnan al-Arabi), their broadcasting facilities being allocated at the Mahallat Abu Shaker Party headquarters' offices near the Gamal Abdel Nasser Mosque.William E. Smith, "Lebanon: A Country's Slow Death", Time, April 29, 1985, p. 47.

They also had a medical relief agency, designated the Lebanese Red Crescent Association (Arabic: جمعية الهلال الأحمر اللبناني | Jameiat al-Hilal al-Ahmar al-Lubnaniyya), best known as Al-hilal for short.

When the Lebanese Civil War broke out in April 1975, as a member of the LNM the INM/Al-Mourabitoun was an active founder of its military wing, the Joint Forces (LNM-JF). The movement claimed that was the first amongst the Lebanese "progressive" militias during the war, and by 1977 it was the largest organization within the LNM-JF, both in terms of popular support and military capacity.

During the 1975-77 phase of the Lebanese Civil War, the al-Mourabitoun militia forces were heavily committed in several battles and suffered considerable casualties, especially at the Battle of the Hotels in October 1975 where they engaged Christian Kataeb Regulatory Forces and Tigers Militia fighters,O'Ballance, Civil War in Lebanon (1998), p. 29. 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.Fisk, Pity the Nation: Lebanon at War, (2001), pp. 99-100.Labaki & Abou Rjeily, Bilan des guerres du Liban (1975–1990) (1993), p. 57.

"[https://www.jstor.org/stable/3012236 Israel in Lebanon, 1975–82] {{webarchive|url=https://web.archive.org/web/20170214181440/http://www.jstor.org/stable/3012236 |date=2017-02-14 }}" in MERIP Reports, No. 108/109, The Lebanon War. (September–October, 1982), pp. 14–20. – 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,O'Ballance, Civil War in Lebanon (1998), p. 36. 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.Kahan, Yitzhak, Barak, Aharon, Efrat, Yona (1983) The Commission of Inquiry into events at the refugee camps in Beirut 1983 FINAL REPORT (Authorized translation) p. 108 has "This report was signed on 7 February 1982." p. 10.

On January 29, 1983, the Israeli-run Front for the Liberation of Lebanon from Foreigners 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.Ronen Bergman, 2018, Rise and Kill First: The Secret History of Israel's Targeted Assassinations, in "notes".

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.Russell, Tom. "[https://www.jstor.org/stable/3010813 A Lebanon Primer] {{webarchive|url=https://web.archive.org/web/20170214181235/http://www.jstor.org/stable/3010813 |date=2017-02-14 }}" in MERIP Reports, No. 133. (June 1985), pp. 17–19. 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. Later during the Coastal War in March–April 1985, the Al-Mourabitoun joined in a Syrian-backed coalition with the Popular Nasserist Organization (PNO), the Druze PSP/PLA and the Shi'ite Amal Movement, which defeated the Christian Lebanese Forces (LF) attempts to establish bridgeheads at Damour and Sidon.O'Ballance, Civil War in Lebanon (1998), p. 156.

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,Stork, Joe. "[https://www.jstor.org/stable/3010810 The War of the Camps, The War of the Hostages] {{webarchive|url=https://web.archive.org/web/20170214181649/http://www.jstor.org/stable/3010810 |date=2017-02-14 }}" in MERIP Reports, No. 133. (June 1985), pp. 3–7, 22. the Lebanese Army,O'Ballance, Civil War in Lebanon (1998), p. 158. 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,William E. Smith, "Lebanon: A Country's Slow Death", Time, April 29, 1985, p. 46. 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).

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.
