The Juliana Republic was declared in the imperial Brazilian province of Santa Catarina on July 24, 1839, and lasted only until November 15, 1839. The Republic was declared in an extension of the Ragamuffin War in the neighboring province of Rio Grande do Sul, where the Riograndense Republic had been declared. The rebels from the Riograndense Republic, who were joined by Italian military leader Giuseppe Garibaldi, attacked Santa Catarina and conquered the harbor and city of Laguna.
