The 1936 Mancomunado Castilla-Aragón was a football competition for clubs based primarily in the Castile region of Spain, including the Community of Madrid, played between 1 September and 3 November 1939.[1] It was organized by the football federations of Spain's central zone (Castilla) and Aragón, hence the name. This tournament was held in the form of a round-robin league and had a total of 30 matches.[1]
It was the fifth 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 it was the last before the outbreak of the Spanish Civil War.[1]
Madrid won with one more point over Real Zaragoza.[2]
