FAQ: When did the Baltimore Orioles start? A: The franchise was founded in 1901 as an MLB team. However, the franchise that would start the ball rolling and later become the Orioles was founded in 1894 as a minor league team based in Milwaukee, Wisconsin, called the Brewers. This is not the same Brewers we think of today however. The 19th century Brewers became a major league team in 1901 when the league -now called the American League—was elevated to major league status.
