Lower Canada Rebellion
When news of the arrest of the Patriote leaders reached Upper Canada, William Lyon Mackenzie launched an armed rebellion in December 1837. In the meantime, filibusters from the United States, the Hunter Patriots, formed a small militia and attacked Windsor, Upper Canada, to support the Canadian Patriots. This resulted in the declaration of martial law by the Lower Canadian government.
Riel Rebellion
The Riel Rebellion (or more precisely Riel Rebellions) is the name often given to two uprisings led by Louis Riel in what are now Manitoba and Saskatchewan.
