Bachir Pierre Gemayel was a Lebanese militia commander who led the Lebanese Forces, the military wing of the Kataeb Party in the Lebanese Civil War and was elected President of Lebanon in 1982.

The Lebanese Forces was one of the main Lebanese Christian factions of the Lebanese Civil War. Originally an umbrella organization for different parties, the Lebanese Forces later became a separate organization. The Lebanese Forces replaced the previous Kataeb Regulatory Forces as the military arm of the Christian Kataeb Party. It was mainly staffed by Maronite Christians loyal to Bachir Gemayel, and fought against the Lebanese National Movement, the Palestine Liberation Organization and the Syrian Army among other enemies. The group gained infamy for their perpetration of the 1982 Sabra and Shatila massacre, which primarily targeted Palestinian refugees following Gemayel's assassination.
