The Lebanese Front was informally organized in January 1976 under the leadership of Pierre Gemayel and Camille Chamoun. It began as a simple coordination or joint command between the predominantly Christian Kataeb Party/Kataeb Regulatory Forces (KRF), Tyous Team of Commandos (TTC), Ahrar/Tigers Militia, Al-Tanzim, Marada Brigade and Lebanese Renewal Party/Guardians of the Cedars (GoC) parties and their respective military wings. The main reason behind the formation of the Lebanese Front was to strengthen the Christian side against the challenge presented by the Lebanese National Movement (LNM), an umbrella alliance of leftist Muslim parties/militias backed by the Palestine Liberation Organization (PLO) and Rejectionist Front Palestinian guerrilla factions.
