Omar al-Mukhṭār Muḥammad bin Farḥāṭ al-Manifī, called The Lion of the Desert, known among the colonial Italians as Matari of the Mnifa, was an Imam and leader of native resistance in Cyrenaica under the Senussids, against the Italian colonization of Libya. A teacher-turned-general, Omar was a prominent figure of the Senussi movement and is considered the national hero of Libya and a symbol of resistance in the Arab and Islamic worlds. Beginning in 1911, he organised and led the Libyan resistance movement against the Italian colonial empire during the First and Second Italo-Senussi Wars. Externally, he also fought against the French colonization of Chad and the British occupation of Egypt. After many attempts, the Italian Armed Forces managed to capture Al-Mukhtar near Slonta when he was wounded in battle by Libyan colonial troops, and hanged him in 1931 after he refused to surrender.

The Second Italo-Senussi War, also referred to as the Pacification of Libya, was a conflict that occurred during the Italian colonization of Libya between Italian military forces and indigenous rebels associated with the Senussi Order. The war lasted from 1923 until 1932, when the principal Senussi leader, Omar al-Mukhtar, was captured and executed. The Libyan genocide took place during and after the conflict.
