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.
Nationalisms in Canada
The influx of British settlers into Canada helped to prompt the development of French-Canadian nationalism which was quite evident during the 1837 rebellion against British rule in Lower Canada. At the same time a few English-speakers in Upper Canada were switching from a British to a Canadian form of identity, as evidenced in the contemporaneous Upper Canada Rebellion, although this was a minority position.
