Viva Cristo Rey!

An "illegal" underground religious procession during the Cristero War (1926–29), a struggle in Mexico against the anti-Catholic policies of the Mexican government, which enacted, under President Plutarco Elías Calles, a statute to enforce the anti-clerical articles of the Mexican Constitution of 1917, which sought to eliminate the power of the Catholic Church. Countless faithful were martyred and 4,000 priests were martyred in or exiled from Mexico for offering the outlawed holy sacrifice of the Mass.

VIVA CRISTO REY!
