This atlas surveys the history of North America from the first settlers to cross the Bering Straits. It looks at the development of the continent's three nations - Canada, the USA and Mexico - from their colonial origins to the formation of the North American Free Trade Association, and assesses the current relationship between the three nations, and that of the region as a whole to the rest of the world. It follows the rise of the USA to superpower status and shows the impact of the two world wars.
