Francisco de Barcelos Rolão Preto, GCIH (February 5/February 12, 1893, Gavião – December 18, 1977, Hospital do Desterro, Lisbon) was a Portuguese politician, journalist, and leader of the Portuguese National Syndicalists Movement (MNS), a fascist organization.
The national syndicalists, also called the "Blue Shirts" (camisas azuis), following the tradition of uniformed right-wing paramilitary groups, was an organisation advocating syndicalism and unionism, inspired by Benito Mussolini's brand of Italian fascism. As Rolão Preto wrote in July 1922, “our organic syndicalism is essentially the basis of current syndicalist thought among Mussolini’s friends”. MNS was also built on previous allegiances to Integralismo Lusitano, but it was not inspired by the Action Française as alleged by their adversaries.
He advocated especially the personalism of Emmanuel Mounier and some of the aspects of unionism. His unionist platform was based on leftist ideas of social justice, such as "a minimum family wage", "paid holidays", "working class education", and a world in which workers are "guaranteed the right to happiness".
Cutting short his lyceum studies, Rolão Preto left for Galicia in Spain, where he joined the monarchist army officer, Henrique Mitchell de Paiva Couceiro, in his 1911-1912 failed attempts to topple the Portuguese First Republic. He then left for Belgium and worked for the integralist magazine, Alma Portuguesa, while completing secondary studies at the Liceu português in Louvain and then attending the Université Catholique there.
