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.
Quebec nationalism
The formal rejection of all 92 resolutions by the Parliament of Great Britain in 1837 led to a radicalization of the patriotic movement's actions. Louis-Joseph Papineau took the leadership of a new strategy which included the boycott of all British imports. During the summer, many popular gatherings ("assemblées populaires") were organized to protest against the policy of Great Britain in Lower Canada. In November, Governor Archibald Acheson ordered the arrest of 26 leaders of the "patriote" movement, among whom Louis-Joseph Papineau and many other reformists were members of parliament. This instigated an armed conflict which developed into the Lower Canada Rebellion.
