The Red River Rebellion began in 1869 when the Métis people of the Red River Valley (in present-day Manitoba) resisted the Canadian government's attempt to establish control over the territory. Led by Louis Riel, the Métis seized forts and established a provisional government to negotiate terms for Manitoba's entry into Confederation. Tensions escalated when Riel's government executed Thomas Scott, an English prisoner. The Canadian government then sent military forces to end the rebellion and bring the territory under its control, forcing Riel to flee to the United States.
