Irish and German immigrants had been recruited in their home countries to serve as mercenaries for Brazil. Upon arrival, they discovered that the promises made by the Brazilian government regarding pay and conditions had not been fulfilled, generating widespread grievance and unrest among the foreign troops.
In 1828, during the Cisplatine War, the discontented mercenaries revolted and seized control of large portions of Rio de Janeiro. The uprising, known in Portuguese as the Revolta dos Mercenários, represented a significant breakdown of military discipline and posed a direct threat to order in Brazil's capital.
Local citizens and troops deployed from French and British warships combined to suppress the revolt and restore control over Rio de Janeiro. The episode highlighted the risks of relying on foreign mercenaries and the consequences of the Brazilian government's failure to honor its commitments to recruited soldiers.
