The Red Shirts (Template:Lang-es) were a paramilitary organization, existing in the 1930s, founded by the virulently anti-Catholic, atheist and anticlerical Governor of Tabasco, Mexico, Tomás Garrido Canabal during his second term.  As part of their attempt to destroy the Church, they systematically destroyed church buildings. The group, created to carry out the governor's orders, takes its name from its uniform of red shirts, blacks pants, and black and red military caps and it consisted of men aged 15 to 30 .
The Red Shirts have been described as "shock troops of indoctrination for the intense campaign against 'God and religion.'" The Red Shirts were also used to attack and suppress the Cristeros, an uprising which rebelled against the persecution of Catholics.  In 1934 Garrido was named secretary of Agriculture by the new president Lázaro Cárdenas, hoping to contain the Red Shirts that way. However Garrido took the Red Shirts with him to Mexico City at the National Autonomous University of Mexico to intervene in student politics. 
On December 30, 1934, the Red Shirts opened fired on Catholics as they were leaving Mass at the Immaculate Conception Church in Coyoacán, killing five and wounding many others.  Garrido sent the murderers a case of Champagne in jail and declared that they were under his protection.  Garrido was fired and exiled shortly after. Not much later the Red Shirts were disbanded.
