1939 Campeonato Mancomunado Centro information

The 1939 Campeonato Mancomunado Centro (Spanish: 1939 Central Joint Championship) was a football competition for clubs based primarily in the Castile region of Spain, including the Community of Madrid, played between 1 October and 19 November 1939. It was organized by the football federations that made up Spain's central zone, hence the name. This tournament was held in the form of a round-robin league and had a total of 30 matches.

It was the sixth joint championship of the Campeonato Regional Centro, after the Centro-Aragón in 1931–32, Centro-Sur in 1932–33 and 1933–34, and Castilla-Aragón in 1934–35 and 1935–36.^[1] The competition was then suspended for three seasons due to the Spanish Civil War.^[1] When the war had ceased in part of Andalusia, the teams from the Andalusian Federation abandoned the Centro tournament, which was suspended, to remake the Campeonato Regional Sur. This meant that the 1939 edition was contested by only six teams from the Madrid and Castilian-Leonese federations, including Real Madrid and Athletic-Aviation Club, the latter being the result of a merge between Atlético Madrid and Club Aviación Nacional, and who ended up winning the title after heading out Madrid on goal difference.^[1][2]

It was the last championship in league format played in the central regional area, due to the suppression of all national regional championships following the consolidation of the national league and its lower divisions.^[3]
