The 20s-30s of the 20th century have gone down in history as "the time of fascism", which is quite true for European countries. A unique phenomenon for the countries of the "South" was the emergence of a mass fascist movement in Brazil - Integralism, which proposed a new model of state-hood and economic system based on nationalism, authoritari-anism, and corporatism common to all fascist movements. Meanwhile, this movement had a number of striking differ-ences from its European counterparts: multiculturalism, non-ethnic and non-racial nationalism, and anti-imperialism. Inte-gralism was Brazil's first truly mass nationwide political movement in its history, whose main difference was the regionalization of politics and the disunity of the elites of the different provinces of the country, thus presenting a model of integration and nationwide modernization of the country. This article analyzes the ideological, political and programmatic foundations of Integralism, its political aspirations and practices.
