Viva Cristo Rey!

Father José Ramón Miguel Agustín Pro Juárez, S.J., also known as Blessed Miguel Pro (born January 13, 1891 – executed November 23, 1927) was a Mexican Jesuit Catholic priest executed under the presidency of Plutarco Elías Calles...

Father Pro was executed without trial. President Calles gave orders to have Pro executed for the assassination attempt, but in reality for defying the virtual outlawing of Catholicism. Calles had the execution meticulously photographed, and the newspapers throughout the country carried photos on the front page the following day. Presumably, Calles thought that the sight of the pictures would frighten the Cristero rebels who were fighting against his troops, particularly in the state of Jalisco. However, they had the opposite effect...

Before the firing squad was ordered to shoot, Pro raised his arms (with a rosary in one hand and a crucifix in the other) in imitation of Christ and shouted the defiant cry of the Cristeros, "Viva Cristo Rey!" – "Long live Christ the King!". When the initial shots of the firing squad failed to kill him, a soldier shot him at point-blank range
