This article is to examine the characteristics of the first foundation of the Islamic Maghreb dynasty through the city of Tlemcen and its characteristics of the dynasty. This shows that primitive Islam in the French-speaking Maghreb region is based on a singular Islamic doctrine. Similarly, looking at the Islamic dynasty of Tlemcen, which was the center of Andalusian culture in the Middle Ages, we examined the status of Tlemcen as an Andalusian cultural center. Tlemcen, which was chosen as the capital of Islamic culture in 2011 by inheriting the Andalusian tradition, is as important in its identity as in its historicity. Because this Maghreb city has helped to Islamize the Iberian Peninsula. Tlemcen also has active exchanges with Mediterranean cities and has also imported and disseminated various cultures. Although the cult of trade has changed depending on power, this city has played the most important role of the Mediterranean Sea by continually expanding its functions and spreading various cultures in sub-Saharan Africa. At the time, it was the Ziyanide dynasty that was in the center and it has important historical values ​​in the sense that it is now the homeland of Algeria. By examining the region of Tlemcen, which is of religious and cultural importance, it was possible to examine the expansion of Andalusian culture in Algeria and the attributes of primitive Islam in the Maghreb.
