The Blueshirts (Spanish: Camisas Azules) was the Falangist paramilitary militia in Spain. The name refers to the blue uniform worn by members of the militia. The colour blue was chosen for the uniforms in 1934 by the FE de las JONS because it was, according to José Antonio Primo de Rivera, "clear, whole, and proletarian," and is the colour typically worn by mechanics, as the Falange sought to gain support among the Spanish working class. In Francoist Spain the Blueshirts were officially reorganized and officially renamed the Falange Militia of the FET y de las JONS in 1940.
The term "Blue Shirts", when used by itself, can refer to several organizations, mostly fascist organizations found in the 1920s and 1930s.
