Униоа де Коимбра

The club was founded on 2 June 2 1919 in Coimbra, Portugal, under the name União Foot-Ball Coimbra Club. Its founders were a group of young people linked to commerce and industry, including shop and workshop owners and employees, bricklayers, locksmiths, tinsmiths, shoemakers, etc., who set up their own "foot-ball" club in the heart of the city's downtown. The first talks took place in the shop of shoemaker Afonso Chato, in Largo do Romal, in October 1918. Subsequent meetings were held in Largo de Sansão, now Praça 8 de Maio, in the heart of downtown Coimbra. Later, the board of directors decided to change the name to Clube de Futebol União de Coimbra (CF União de Coimbra).

The club's traditional stadium in Coimbra city proper, the Campo da Arregaça, was inaugurated in 1928 and built by the Coimbra City Hall, but in the 21st century the club has also played for some periods of time in the Estádio Municipal Sérgio Conceição, another City Hall-owned 2,500 seat stadium in Taveiro, a civil parish of Coimbra Municipality located in the outskirts of the city proper, which is a municipal stadium built in 2002 and was named after Coimbra-born football player Sérgio Conceição.

The main football team of União de Coimbra played one single season in the Portuguese First Division, in the 1972-1973 season, among big clubs like FC Porto, Benfica and Sporting Clube de Portugal. However this season coincided with hometown big club Académica de Coimbra being in Segunda Divisão as a result of being relegated the previous season, so a top division Coimbra derby never took place.

In 2016, due to legal reasons related with the club's financial distress and subsequent reorganization after its bankruptcy, the club was forced to change its name to Clube União 1919.
