Juliana Republic in the context of "Provinces of Brazil"

Giuseppe Maria Garibaldi (/ˌɡærɪˈbɑːldi/ GARR-ib-AHL-dee, Italian: [dʒuˈzɛppe ɡariˈbaldi] ; 4 July 1807 – 2 June 1882) was an Italian general, revolutionary and republican. He contributed to the Unification of Italy (Risorgimento) and the creation of the Kingdom of Italy. He is considered to be one of Italy's "fathers of the fatherland", along with Camillo Benso di Cavour, King Victor Emmanuel II and Giuseppe Mazzini. Garibaldi is also known as the "Hero of the Two Worlds" because of his military enterprises in South America and Europe.

Garibaldi was a follower of the Italian nationalist Mazzini and embraced the republican nationalism of the Young Italy movement. He became a supporter of Italian unification under a democratic republican government. However, breaking with Mazzini, he pragmatically allied himself with the monarchist Cavour and Kingdom of Sardinia in the struggle for independence, subordinating his republican ideals to his nationalist ones until Italy was unified. After participating in an uprising in Piedmont, he was sentenced to death, but escaped and sailed to South America, where he spent 14 years in exile, during which he took part in several wars and learned the art of guerrilla warfare. In 1835 he joined the rebels known as the Ragamuffins (farrapos), in the Ragamuffin War in Brazil, and took up their cause of establishing the Riograndense Republic and later the Catarinense Republic. Garibaldi also became involved in the Uruguayan Civil War, raising an Italian force known as Redshirts, and is still celebrated as an important contributor to Uruguay's reconstitution.

The Riograndense Republic, often called the Piratini Republic (Portuguese: República Rio-Grandense or República do Piratini), was a de facto state that seceded from the Empire of Brazil and roughly coincided with the present state of Rio Grande do Sul. It was proclaimed on 11 September 1836 by general Antônio de Sousa Neto as a direct consequence of the victory obtained by gaúcho oligarchic forces at the Battle of Seival [pt] (1836) during the Ragamuffin War (1835–1845). It had a constitution adopted in 1843 and was recognised only by the United Kingdom, France, and Uruguay.

In 1839, the Riograndense Republic formed a confederation with the short-lived Juliana Republic (Portuguese: República Juliana) which proclaimed its independence in the same year. November 1839, however, saw the war result in the defeat and disappearance of the Juliana Republic. The Riograndense Republic had five capitals during its nearly nine years of existence: the cities of Piratini (for which it is often called Piratini Republic), Alegrete, Caçapava do Sul (official capitals), Bagé (for only two weeks), and São Borja. The war between the Gaúchos and the Brazilian Empire was ended by the Ponche Verde Treaty.

Laguna is a Brazilian municipality located in the southern state of Santa Catarina, 120 kilometers south of the state's capital, Florianópolis, and north east of Porto Alegre. The population is 46,122 (2020 est.) in an area of 336.4 km. The elevation is 2 m. The BR-101 coastal highway passes through the municipality.

The city was founded in 1676 by rural people of the capitania of São Vicente. In 1714, the locality was recognized as a municipality, and in 1847 it received the status of city. It was the capital of the short-lived Juliana Republic in 1839. The city's flag is a tricolor with yellow, white and green, and has a coat of arms in the middle.
