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.
History of Ontario
Many men chafed against the anti-democratic Family Compact that governed through personal connections among the elite, which controlled the best lands. This resentment spurred republican ideals and sowed the seeds for early Canadian nationalism. Accordingly, rebellion in favour of responsible government rose in both regions; Louis-Joseph Papineau led the Lower Canada Rebellion and William Lyon Mackenzie led the Upper Canada Rebellion. The rebellions failed but there were long-term changes that resolved the issue.
