The Irish and German revolt (Portuguese: Revolta dos Mercenários) in Brazil was a revolt of German and Irish mercenaries in 1828 during the Cisplatine War of 1825–1828. The immigrants, who were recruited in their homelands to come to Brazil, discovered that the promises made to them by the Brazilian government were not fulfilled. In the revolt, the Irish and Germans took control of large parts of Rio de Janeiro. Citizens of the town and troops from French and British warships suppressed the revolt.
