Historical writing about the middle years of the 1860s in British North America has focused almost exclusively on the Confederation movement and the theme of nation-building.

Through an exhaustive study of period documents, Ian Ross Robertson examines the origins, the modus operandi, and the impact of this organization. In doing so, he has illuminated a rich part of Canadian history.
