Ragamuffin War

The Ragamuffin War or Ragamuffin Revolution was a Republican uprising that began in southern Brazil, in the province of Rio Grande do Sul in 1835. The rebels were led by generals Bento Gonçalves da Silva and Antônio de Sousa Neto with the support of the Italian fighter Giuseppe Garibaldi. The war ended with an agreement between the two sides known as Green Poncho Treaty in 1845.

Over time, the revolution acquired a separatist character and influenced separatist movements throughout the entire country such as the Liberal Rebellions in São Paulo, Rio de Janeiro, and Minas Gerais in 1842, and the Sabinada in Bahia in 1837.
