The Mexican Constitution of 1917 was founded on seven fundamental ideals:
A declaration of rights, sovereignty of the nation, separation of powers, representative government, a federal system, constitutional remedy and the supremacy of the State over the Church. It enacted land reforms, limited foreign ownerships of key resources and guaranteed the rights of workers.
It placed restrictions on clerical education and church ownership of property. The restrictions placed on the Roman Catholic Church led to the violent Cristero War of the mid 1920s. Most of these were repealed by President Carlos Salinas in 1992.
