MCアルジェU21

In 1921, a group of youths from the Casbah and Bab El Oued neighborhoods joined to create the first Muslim football club in colonized Algeria. The group was led by Hamoud Aouf, who served as a liaison between the two groups. On August 7, 1921, the club was officially founded in the waiting room of the Benachere café. The date coincided with the Mawlid, hence the name Mouloudia Club d'Alger. Green, for the hope of the Algerian people and the traditional colour of Islam, and red, for the love of the nation, were chosen as the club colours.

In 1976, MC Alger qualified for the African Cup of Champions Clubs for the first time in its history after winning the 1974–75 Algerian Championnat National. They reached the final after beating Al-Ahly Benghazi of Libya, Al Ahly of Egypt, Luo Union of Kenya and Enugu Rangers of Nigeria, respectively. In the final, they met Guinean club Hafia Conakry, who had won the last edition of the competition. In the first leg in Conakry, MC Alger lost 3–0 and faced the difficult task of having to score three goals in the return leg. However, in the return leg, they managed to score the three goals with a brace from Omar Betrouni and a goal from Zoubir Bachi. They went on to win the penalty shootout 4–1 to win their first African title and also become the first Algerian club to win a continental competition.
