Bagé (Portuguese pronunciation: [bɐˈʒɛ]) is a Brazilian municipality located in the state of Rio Grande do Sul.

Prior to official reorganization as a city, Bagé was seized by military forces from Uruguay and Argentina.

Because of its location on the shortest route between Porto Alegre and Montevideo, Bagé has played an important role in the history of Brazil and the state of Rio Grande do Sul.

The first contact between the local Amerindians (Charruas) and the Spanish occurred in the second half of the seventeenth century when the Jesuits established a mission called Redução de Santo André dos Guenoas, in 1683.

In 1773, the governor of Buenos Aires, Juan José de Vértiz y Salcedo, left the region of the River Plate to expel the Portuguese from Rio Grande do Sul with 5,000 men.

After signing the First Treaty of San Ildefonso in 1777 a Spanish garrison again occupied the fort now at the border between the two empires.

On 17 July 1811 Sousa left with his troops to invade the Banda Oriental (present-day Uruguay) to conquer it and annex all the territory leaving the Uruguay River as a new border between Argentina and Brazil, some camp followers who could not keep up with the movement of the troops founded the present-day city.

In 1825 Carlos de Alvear invaded the territory from Uruguay and in 1827 the forces of general Juan Antonio Lavalleja conquered the town.

Brazil accepted Uruguay's independence but in exchange kept some of the borderlands previously disputed for centuries between Spain and Portugal.

One of the most important, the Battle of Seival, took place between imperialist and republican forces led by Antônio de Souza Netto.

In this year Gumercindo Saraiva invaded Rio Grande do Sul and at Passo do Salsinho, the first combat took place.

With the end of combats the beginning of the twentieth century seemed promising as Bagé had potential to become an industrial and agricultural center.

Narratives from this period show that the climate was benign and the soil rich in natural resources, with special mention of the coal mines of Candiota and Rio Negro.

Other distances from Bagé are: Comandante Gustavo Kraemer International Airport serves the city and the region although currently no scheduled flights operate to and from it.

The Dom Diogo de Souza Museum in Bagé displays cultural and historical artifacts from the city and surrounding region.
