The Manitoba-Dakota League was an independent baseball league based in Manitoba and North Dakota that was founded in 1950. It became the home for many African-American and Latino players. The league lasted through the 1957 season. It was known informally as the Mandak League or Man-Dak League. The league originated as the Manitoba Senior Baseball League founded in 1948, with Jimmy Dunn as its president.
It was the outlet for former Negro leaguers to continue playing and entertaining fans, occupying fields with ex-major leaguers, minor league stars and some of the best Manitoba, North Dakota, and Minnesota born players. It featured such greats as Willie Wells, Leon Day, Ray Dandridge and Satchel Paige, who pitched briefly for the Minot Mallards in 1950.
