Federal intervention from Mexico City continued into the 1920s, with a number of laws to reform schools, hospitals and other institutions, which before had been mostly operated by the Catholic Church. This was opposed by many in the state who supported the Church's formerly prominent role in political and social affairs. The Ley de Cultos (Religion Law) of 1926 gave rise to the Cristero War pitting those favoring the Catholic Church against those favoring agrarian and socialist reform. Battles and skirmishes related to this conflict took place in a number of locales in Mexico but it cause severe problems in Colima, causing major divisions with no formal resolution.
