Most Canadians were strongly opposed to the prospect of American annexation. Reports of the Annexation Bill of 1866 — a bill that, contrary to myth, never came to a vote — might have been one of the many factors behind Canadian Confederation in 1867. Much more serious were the Fenian raids made by Irish Americans across the border in 1866, which spurred a wave of patriotic feeling that helped the cause of Confederation.[8]
