For the history of the relations of the English colonies with Canada before the Revolution, see New France and Quebec Act. The Continental Congress attempted, but without avail, to induce Canada to take part in the Revolution. In 1775 Montgomery and Arnold conducted an expedition into Canada, which ultimately failed. From Canada Burgoyne invaded New York in 1777. The land operations of the War of 1812 were mainly efforts for the conquest of Canada. Since then our relations with Canada have been mostly in the way of trade, though the sympathy of Americans with Canadian insurgents in 1837, the Caroline affair, the Aroostook disturbances and the Fenian invasion of 1866 have at times interrupted friendliness. The treaty of 1871 provided for the free transit of certain goods into Canada through the United States and into the United States through Canada. There has been of late years a strong movement for the annexation of Canada to the United States.
