In 1950, composed of only Moroccan players, Raja began its journey from the lowest tier of the national football structure, and came at the top of the 4th division (Groupe Chaouia-Nord). The team played in the 1st Division (3rd tier) for a single season, finishing second of the 1951–52 edition and earning promotion to the Pré-honneur Division (second tier) where it would play for three seasons before sports competitions were boycotted then stopped in 1955. The following year, Raja will dominate the play-offs and established itself as one of the founding members of Botola under the newly created Royal Moroccan Football Federation, and played the first edition that debuted on 15 November 1956. Since this day, Raja is one of only three clubs never to have been relegated from the top tier of Moroccan football, the others being Wydad AC and AS FAR.
