The 1930 revolution began in Rio Grande do Sul on October 3 at 5:25pm. Osvaldo Aranha telegraphed Juarez Távora to communicate the beginning of the Revolution. It spread quickly through the country. Eight state governments in the northeast of Brazil were deposed by revolutionaries.
On October 12 and 13, the Battle of Quatiguá took place (possibly the biggest fight of the revolution), although it has been little studied. Quatiguá is located to the east of Jaguariaíva, near the border between São Paulo state and Paraná.
