BAGS, a town and municipality of the State of Rio Grande do Sul, Brazil, about 176m. by rail W.N.W. of the city of Rio Grande do Sul. Pop. of the municipality (1920) 46,298; of the town 24,424. It is situated in a hilly region 7 74f t. above sea-level, and is the commercial centre of a large district on the Uruguayan border in which pastoral occupations are predominant. This region is the watershed for southern Rio Grande do Sul, from which streams flow east and south-east to the Atlantic coast, and north west and south-west to the Uruguay river. The town dates from colonial times, and has always been considered a place of military importance because of its nearness to the Uruguayan frontier, only 25m. distant. It was captured by the Argentine general Lavalle in 1827, and figured conspicuously in most of the civil wars of Argentina. It is also much frequented by Uruguayan revolu tionists.
