Campeonato Centro (also known as Trofeos Mancomunados from 1932 to 1936) was the most important regional football competition for clubs based in the community of Madrid in the first half of the 20th century.
The competition was originally founded in 1903 and ran by the local Madrid Football Federation (Spanish: Federación Madrileña de Foot-Ball or FMF). From 1903 to 1913 it was referred to as "Campeonato de Madrid" and was open to clubs based in the community of Madrid.
In 1913 the Royal Spanish Football Federation (Spanish: Real Federación Española de Fútbol or RFEF) was established to govern competitions at the national level and the FMF was re-established as one of its regional branches, named Federación Castellana de Fútbol (FCF). As part of the country-wide reorganisation the competition was also re-established as "Campeonato Regional de Madrid". In the following years it was one of the four regional competitions used as a qualifying phase for the Spanish Cup (which acted as the national championship of Spain until the foundation of La Liga in 1929). The four regional competitions were territorially organized as follows:
Región Norte (Álava, Vizcaya, Guipúzcoa, Navarra and Rioja).
Region Centro (Castilla and Andalucia).
Región Este (Cataluña, Valencia, Alicante and Murcia).
Región Oeste (Santander, Asturias and Galicia)
With minor changes in territorial organization and several renamings (see below), these four regional competitions were contested until 1940 when it was disbanded during Franco's dictatorship.
From 1903 to 1913 the competition was contested by clubs from Madrid. From the 1913–14 season onwards it expanded to include teams from six neighboring provinces (Ávila, Ciudad Real, Cuenca, Guadalajara, Segovia and Toledo). The territorial format remained largely unchanged until the last season in 1939–1940, with minor changes listed below.
