Cristero War
The Cristero War (Spanish: La guerra cristera), also known as the Cristero Rebellion or La Cristiada [la kɾisˈtjaða], was a widespread struggle in central and western Mexico from 3 August 1926 to 21 June 1929 in response to the implementation of secularist and anticlerical articles of the 1917 Constitution. The rebellion was instigated as a response to an executive decree by Mexican President Plutarco Elías Calles to strictly enforce Article 130 of the Constitution, an implementing act known as the Calles Law.
