Guerrilleros de Cristo Rey (lit. "Warriors of Christ the King") was a Spanish paramilitary fascist group that operated in the late 1970s. They emerged at a time of factionism within the Carlist movement. Historically Carlism was a traditionalist, legitimist and Catholic movement, supporting a different monarchial line to the one occupying the Spanish throne. But when the succession fell to Carlos Hugo, he began to support Social Democracy ideology under the banner of the Carlist Party. This caused large scale conflict within the movement; many proclaimed his more traditionalist minded brother, Sixtus Henry, as Carlist regent.
