Isidoro decided to go into exile in Argentina, from where he continued to voice his support for the rebels. Because of his prestige among those forces he became known as “Marshal of the Revolution”. In 1927 the campaigns by the Prestes Column ended, and some of its leaders joined Lopes in Argentina. In time most, including Lopes, were marginalised, and the disunity in the rebel movement left only Carlos Prestes as the recognised leader. Revolution of 1930 In 1930, with the victory of Júlio Prestes in the presidential elections, the defeated candidate Getúlio Vargas began to plan a coup d’etat against president Washington Luis. Isidoro Dias Lopes joined his movement, the most senior military figure to do so. However, he was eventually displaced by Colonel :Pt:Pedro Aurélio de Góis Monteiro.
