The story of Canada since 1867 is, in many ways, a successful one: For a century and a half, people of different languages, cultures and backgrounds, thrown together in the vast, northern reaches of a continent, built a free society where regional communities could grow and proper, linked by the common thread of an emerging national identity. There were false steps along the way, including the struggles of Aboriginal people for survival, and the ever-present tensions over federal unity. But for the most part, Canada became an example to the world of a modern, workable nation state.
