Louis Riel was a Métis leader in Manitoba and the Northwest Territories in Canada in the late 1800s. He fought for Métis rights and led the Red River Rebellion and Northwest Rebellion, establishing the short-lived Provisional Government of Manitoba. Riel was eventually found guilty of high treason for his role in the Northwest Rebellion and was hanged in 1885, making him a controversial figure as either a hero or menace in Canadian history.
