The "Tanzim Party" (Arabic: حزب التنظيم | "Hizb al-Tanzim") or "Parti du Tanzim" in French as its name implies, was a MoC/"Tanzim" splinter faction established by Georges Adwan shortly after being ousted from that organization's presidency in late 1976. Backed by Syria, the group was about 100-200 men-strong, backed by a few technicals equipped with HMGs and recoilless rifles, and operated from the Muslim-held sector of West Beirut. However, during the Hundred Days' War in February 1978, most of the "Tanzim Party" militiamen switched sides to rejoin their former party' comrades of the MoC/"Tanzim" militia and fought ferociously against Syrian Army troops at the Fayadieh and Yarze districts of East Beirut. Thus deprived of its fighting force, the "Tanzim Party" was gradually pushed to the sidelines and ceased its activities around the mid-1980s.
