SENUSSI and SENUSSITES, the names respectively of a Muslim family (and especially its chief member) and of the fraternity or sect recognizing the authority of the Senussi.
Seyyid or Sidi (i.e., Lord) Mohammed ben Ali ben Es Senussi el Khettabi el Hassani el Idrissi el Mehajiri, the founder of the order, commonly called the Sheikh es Senussi, was born near Mostaganem, Algeria, and was called es Senussi after a much venerated saint whose tomb is near Tlemsen. The date of his birth is given variously as 1791, 1792, 1796 and 1803. He was a member of the Walad Sidi Abdalla tribe of Arabs and his descent is traced from Fatima, the daughter of Mohammed. As a young man he spent several years at Fez, where he studied theology. When about 3o years old he left Morocco and travelled in the Saharan regions of Algeria, preaching a reform of the faith. From Algeria he went to Tunisia and Tripoli, gaining many adher ents, and thence to Cairo, where he was opposed by the Ulema of El Azhar, who considered him unorthodox. Leaving Egypt Senussi went to Mecca, where he joined Mohammed b. Idris el Fassi, the head of the Khadirites, a fraternity of Moroccan origin. On the death of el Fassi Senussi became head of one of the two branches into which the Khadirites divided, and in 1835 he founded his first monastery at Abu Kobeis, near Mecca. While in Arabia Senussi visited the Wahhabites, and his connection with that body caused him to be looked upon with suspicion by the Ulema of Mecca. It was at Mecca, however, that Senussi gained his most powerful supporter, Mohammed Sherif, a prince of Wadai, who became in 1838 sultan of his native State, then the most power ful Mohammedan kingdom in the central Sudan. Finding the opposition to him at Mecca too powerful Senussi quitted that city in 1843 and settled in Cyrenaica, where in the mountains near Derna he built the Zawia Baida, or White Monastery. There he was in close touch with all the Maghribin, gaining many followers among the Tripolitans and Moroccans. The spread of the Senus sia was, however, not viewed with favour by the Turks, who at that time ruled Cyrenaica. Probably with the desire to avoid pressure from the Turks, Senussi removed in 1855 to Jaghbub, a small oasis some 3om. N.W. of Siwa. Here he died in 1859 or 186o, leaving two sons, one Mohammed Sherif (named after the sultan of Wadai), born in 1844, and the other, el Mandi, born in 1845. To the second son was left the succession. It is related
that as the younger son showed a spirit in all things superior to that of his brother the father decided to put them to the test. Before the whole zawia at Jahgbub he bade both sons climb a tall palm tree and then adjured them by Allah and His Prophet to leap to the ground. The younger lad leapt at once and reached the ground unharmed ; the elder boy refused to spring. To el Mandi, "who feared not to commit himself to the will of God," passed the birthright of Mohammed Sherif. Mohammed appears to have accepted the situation without complaint. He held the chief administrative position in the fraternity under his brother until his death in 1895.
