Abu Hammu II (died 1389) was an Abdalwadid Sultan of the Kingdom of Tlemcen in Algeria in the 14th century.
Navarro personally led the Spanish forces during the conquest of Bougie (Béjaïa), Algiers, Tunis, Tlemcen, and Tripoli in 1510.
The ruler of Tlemcen, Ibn Tashufin (r. 1318-1337), initiated hostilities against Ifriqiya, besieged Béjaïa, and sent an army into Tunisia that defeated the Hafsid king Abu Yahya Abu Bakr II, who fled to Constantine while the Zayyanids occupied Tunis.
News of the deal infuriated the Nasrid ruler Muhammad II al-Faqih of Granada, who promptly sought out the support of Alfonso X of Castile and the Abdalwadid ruler Yaghmorassan of Tlemcen to punish the Marinids.
Ahmad came back after two years, and was able to rule from 1547 and 1549, until 1549 when Fez and then Tlemcen were conquered by his southern Saadian rivals under their leader Mohammed ash-Sheikh.
After passing through the École Biblique, he moved to Algeria to Tlemcen in the Diocese of Oran where he responded to the call of his order to refound a Dominican presence, six years after the assassination of Monsignor Pierre Claverie.
This continued to be the main sphere of his activity for sixteen years, and he won special distinction in his fifteen months' command of the exposed garrison of Tlemcen, a command for which he was selected by Marshal Bertrand Clausel (1836–1837), and in the defence of Cherchell (1840).
This work, owing to its literary value, was translated into Yiddish (1687), into German (1720), and into French by Daniel Levy (published by Benjamin II., Tlemçen, 1855).
14th-century Muslim flags with an upward-pointing crescent in a monocolour field included the flags of Gabes, Tlemcen (Tilimsi), Damas and Lucania, Cairo, Mahdia, Tunis and Buda.
The park includes the forests of Ifri, Zariffet, and Aïn Fezza, the waterfalls and cliffs of El Awrit, and many archeological sites and the ruins of Mansoura, the ancient city on whose ruins Tlemcen was built, as well the Mosque of Sidi Boumediene, the patron saint of Tlemcen.
Yusuf was an effective general and administrator, as evidenced by his ability to organize and maintain the loyalty of the hardened desert warriors and the territory of Abu Bakr, as well as his ability to expand the empire, crossing the Atlas Mountains onto the plains of Morocco, reaching the Mediterranean and capturing Fez in 1075, Tangier in 1079, Tlemcen in 1080, and Ceuta in 1083, as well as Algiers, Ténès and Oran in 1082-83.
