Cipriano Reyes

Cipriano Reyes (7 August 1906 – 1 August 2001) was an Argentine politician and labour union leader. He led several labour organizations related to the meat industry and also founded the Labour Party. Initially a supporter of Juan Domingo Perón, he was a key figure in organizing the mobilization of 17 October 1945 to demand Perón's release, an event that later became a symbol of Peronist iconography, known as Loyalty Day.
