In response to the gradual disappearance of the Movimiento Nacional Socialista as the dominant force of the extreme right during the course of 1938, new groups emerged on Chileʼs political scene. The Partido Nacional Fascista and the Movimiento Nacionalista de Chile, established in October 1938 and February 1940 respectively, attempted to assume the role of nacismo after it had turned to the left. Operating in a national and international environment, which became increasingly detrimental to the development of national fascist organisations, these new voices of Chilean fascism never managed to build up substantial support. They remained on the sidelines of the political system. The return of the Vanguardia Popular Socialista (the name of the MNS since January 1939) to its fascist roots in the (Chilean) autumn of 1940 did not revive the dwindling forces of the radical right. The Vanguardia, the Movimiento Nacionalista and a number of smaller groups that followed the former dictator Carlos Ibáñez established the Unión Nacionalista in March 1942, but this was a last desperate attempt to breathe new life into a dying cause.
