The club was founded in 1933 and started off life in the Spanish 5th tier. They finished 2nd that year and gained promotion to the 4th tier, where they remaind for the next four seasons.
In 1942-43, the club managed to win promotion, climbing to the 3rd tier, but their stay at this level only lasted two seasons. After finishing a respectable 5th in the 1943-44 season, they finished 10th in the 1944-45 season and dropped down to the 4th tier once again.
But the 1945-46 season saw the club promoted immediately, with ambitions to climb the league ladder once again. Their progress was halted for three years until, finally, they managed to win promotion in the 1948-49 season to the 2nd tier.
Not content with staying in the second division, they created the most memorable moment in the clubs history when they gained promotion in the 1950-51 season, winning the league and finally reaching the top flight of Spanish Football.
It was to be a short stay. However, when the club finished the bottom of the table, only recording 7 wins all season. But they did manage some eye-catching results, most namely drawing 3-3 with Real Madrid and beating Athletico Madrid, 4-1 at home.
But that was the highest the club would ever get, playing the next four seasons, the Segunda, until 1956, when they merged with Sociedad Deportiva Ceuta to create AgrupaciĂłn Deportiva Ceuta FĂştbol Club.
The most interesting fact about Club Atlético Tetuán is that they weren't Spanish at all. They played their home games in the Saniat Rmel Stadium in Tetuán, which in the North African Country of Morocco, which, of course, was under control by Spain until 1956.
