The 36 men traditionally regarded as the Fathers of Confederation were those who represented British North American colonies at one or more of the conferences that lead to Confederation on 1 July 1867, including the Charlottetown Conference (September 1864), the Québec Conference (October 1864) and the London Conference (1866–67).
George Brown played an instrumental role in establishing Confederation. As leader of the Clear Grits (forerunner of the Liberal Party) in Canada West, he set aside political differences and allied with his Conservative rivals John A. Macdonald and George-Étienne Cartier in 1864, with whom he pitched Confederation to the Atlantic colonies at the Charlottetown and Québec Conferences. From 3 February to 13 March 1865, politicians in the Province of Canada debated the terms of Confederation, offering some of the most compelling defences and critiques of the union of British North American colonies. In the following speech, delivered before the legislature of the Province of Canada on 8 February 1865, Brown explains his reasons for supporting Confederation.
