Viva Cristo Rey is Spanish for long live Christ the King and became a defining cry of Mexican Catholics during the Cristero War of 1926 to 1929, when the government restricted public worship. The phrase was famously associated with martyrs who reportedly shouted it before execution, and it later entered wider Catholic culture through films, books and commemorations of the conflict. Today it remains a slogan of traditional Catholic identity, heard at pilgrimages, rallies and online clips celebrating faith, and its short, chant-like form makes it easy to reuse as an audio slogan.
