Beginning of the war The uprising is believed to have begun over the difference between the economy of Rio Grande do Sul and that of the rest of the country. Unlike the other provinces, the economy of Rio Grande do Sul focused on the internal market rather than exporting commodities. The province's main product, (dried and salted beef), suffered badly from competition from imported from
Uruguay and
Argentina. The people that benefited from these markets were called : nomadic cowhands and farmers who lived in
Rio Grande do Sul. The Gaúchos also lived in Argentina and Uruguay. On 20 September 1835, General Bento Gonçalves
captured the capital,
Porto Alegre, beginning an uprising against the perceived unfair trade reinforced by the provincial government. The provincial president fled to the city of
Rio Grande, to the south. In Porto Alegre, the rebels, also known as "ragamuffins" () after the fringed leather worn by the gaúchos, Responding to the situation and further upsetting the rebels, the Brazilian regent,
Diogo Antônio Feijó, appointed a new provincial president, who was forced to take office in exile in Rio Grande. The Brazilian Army had a number of problems at the time and was not able to handle the secessionist threat. Through military reforms, the mass recruitment of civilians was made possible and they were able to quell the rebels in 1845. Led by the
Italian revolutionary
Giuseppe Garibaldi, who joined the rebels in 1836, and his wife,
Anita Garibaldi, the revolution spread north through
Santa Catarina, which adjoined Rio Grande do Sul. Without an appropriate port for their newborn republican navy, the revolutionaires aimed for one of the main cities of Santa Catarina,
Laguna, which was
taken by the rebels but
fell back into imperial hands after four months. It was in this struggle that Garibaldi gained his first military experience and got on the road leading to his becoming the famed military leader of the
Unification of Italy. The rebel forces were also aided financially and indirect military support by the
Uruguayan government led by
José Fructuoso Rivera. The
Uruguayans had the intention of creating a political union with the
Riograndense Republic to create a new stronger state.
Resultant peace The rebels refused an offer of amnesty in 1840. In 1842, they issued a Republican
constitution as a last attempt to maintain power. The same year saw
General Lima e Silva take command of Imperial forces in the area and try to negotiate a settlement. On 1 March 1845, the peace negotiations led by Lima e Silva and
Antônio Vicente da Fontoura concluded with the signing of the Green Poncho Treaty (Portuguese: Tratado de Poncho Verde) between the two sides, in
Dom Pedrito. The treaty offered the rebels a full amnesty, full incorporation into the imperial army and the choice of the next provincial president. All the debts of the Riograndense Republic were paid off by the Empire and a tariff of 25% was introduced on imported charque. The Riograndense and Juliana Republics remained in the
Empire of Brazil and are now two states of the
Federative Republic of Brazil,
Rio Grande do Sul and
Santa Catarina respectively. As a goodwill gesture, the rebels chose Lima e Silva as the next provincial president. == Participants ==
