Abu Said Uthman I  Abu Said Uthman I, or "Othmane Ibn Yaghmoracen", or in Algerian arabic ( أبو سعيد عثمان الأول, Abu Sa'id Othman āl-awel), ruled the Zenata Berber Kingdom of Tlemcen in Medieval Algeria from 1283 to 1303. Abu Said Uthman I succeeded his father Abu Yahya Yaghmurasen ibn Zayyan (1236–1282) as ruler of the Zayyanid dynasty. He was the pearl of perfection, lord of (diverse) fractions of the Abd el-Wad family. He was the bravest and one of the most fearsome warriors of his tribe  He annexed to his empire the countries of his enemies and defended the lands of his subjects. His empire was luxurious and the cities were said to have been well administrated. Through marriages with the Hafsids, he was able to establish good relations with his eastern neighbors. This allowed Uthman I to withstand the ongoing attacks of the Marinids of Fez. The fighting led to devastating results in his Empire. The siege of Tlemcen by the Marinids was maintained from 1299 to 1307 during which the Marinids built the siege city of al-Mansura, which was at times even residence of the Marinid rulers. Despite the superiority of the Marinids, the Zayyanids were able to assert themselves, showing the support the dynasty had by the population of the empire. Uthman I did not live to see the end of the siege. Only under his successor Abu Zayyan I Muhammad (1303-1308) did the Marinids withdraw back to Al-Maghrib (al-Aqsa) after the death of their Sultan and as dynastic infighting broke out there. Uthman I was a warrior, he took part in many sieges and battles consolidating his power within his empire and against his rivals (mainly the Marinids). Abu Said Uthman I was considered to be a great ruler, he managed to conserve the integrity of his empire repelling four attacks by the Marinid Abou Ya‘qoûb ben‘Abd el H’aqq (died during the 5th)  and punished the rebels who revolted against him.
