It was recognized as a political entity on 20 May 1931 and received juridical personality on 11 January 1932. The movement was formed by
Argentine President General
José Félix Uriburu officially as a reserve for Argentina's armed forces. The movement's members were authorized to receive military training. The Legion was the largest nationalist organization in Argentina in the early 1930s. The movement is known to have committed acts of violence against its political opponents and tortured those that were captured. The Legion's women section called
Agrupación Femenina de la LCA promoted women to love the armed forces and respect for order, authority, and hierarchy in the home and school. This coincided with the election of
Juan Perón as
President of Argentina. In 1953, the ALN condemned the nationalist newspaper La Prensa for publishing too many articles by Jewish writers. ALN leader Juan Queraltó was ousted from leadership of the party in 1953. Queraltó was succeeded by
Guillermo Patricio Kelly. Kelly sought to distance the party from its anti-Semitic past and met with
Israel's ambassador to Argentina, Dr.
Arie Kubovy during which Kelly informed Dr. Kubovy that the ALN had forsworn anti-Semitism. In 1954, anti-Semitism was dropped from the party. Kelly was arrested in the aftermath by Argentine authorities, but eventually managed to escape and fled the country in 1957. In 1973, after the comeback of Perón to power, former members, including Kelly and Queraltó, attempted a revival of the ALN, but were overshadowed by newer far right groups which eventually became subordinated to the
Argentine Anticommunist Alliance. == Party symbols ==
