[7] This town has Berber vestiges dating from the Almohad period, from the time of the flourishing growth of the city which was an important center of trade flows between the two shores of the Mediterranean.

[8] The founder of the Almohad dynasty, Ibn Ali El Koumi, later established in Marrakech, was born in Tajra, a hill overlooking Honaïne, two kilometers to the west.

[9] In 1162, Oran and Honaïne joined forces to build the hundred ships commanded by Abd El Moumen Ben Ali.

Heading eastwards, the Almohad (الموحدون in Arabic) troops commanded by Abd El Moumen Ben Ali arrived at the mountains of Tlemcen.

Only the "veiled men" who held the Balearics escaped: the Beni Ghanya, who will play a not insignificant role in the history of Algeria.

Ibn Toûmert will meet Abd El Moumen near Bougie (present Bejaïa), during his trip to the Orient (1117).

The Master of the Under recognized in him the predestined man: "The mission on which the life of religion will rest will triumph only by Abd El Moumen, the torch of the Almohades.

From this period dates the first cadastre of North Africa in 1159, Abd El Moumen ordered the surveying of Ifriqiyya and the Maghreb.

It was first Spain, which escaped the Almohad caliphate, followed by the Hafsides in 1229 (present-day Tunisia), Tlemcen with the Zianides in 1235 (current Algeria), and the Merinids in 1269 (present Morocco) who took Marrakech.
