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.
Family Compact
Mackenzie's frustration with Compact control of the government was a catalyst for the failed Upper Canada Rebellion of 1837. Their hold on the government was reduced with the creation of the united Province of Canada and later the installation of the system of Responsible Government in Canada.
