Sport Lisboa e Elvas (founded in 1925) and O Elvas CAD spent several years in the Portuguese Liga, the main tier in the Portuguese football league system.

The union between the two clubs from Elvas was fundamentally due to the lack of interest shown by the so-called mother clubs, since in the mid-1940s, both SL Elvas and SC Elvense were experiencing some financial difficulties and given the lack of aid several times requested and refused by their mother clubs, they decided to unite in a single club and in this way, managed to keep the king sport alive in the interior region.

In 1980/81, "O Elvas" lost the final of the 3rd Division Nacional, with the title being won by CF União de Coimbra in the second phase of the competition.

When the crisis knocked on the door, the club went downhill until it descended to the District Championship of the Football Association of Portalegre and for that reason for years it only relied on the academy.

The club already had the modality of basketball, which participated in the competitions of the "Associação de Basquetebol do Alentejo", also in the youth and senior levels, but which currently has its activity suspended.
