[North America]

One of the last maps to show an independent Republic of Texas.

The North American continent of the mid-19th century is presented in some detail on this map, published in either 1846 or 1847 as part of Histoire generale des missions catholiques by Mathieu Richard A. baron Henrion. The image presents a variety of interesting contemporary information between the Arctic Circle and Central America; including indigenous tribes, geographic features, frontier fortifications, and Catholic missions.

Dotted outlines indicated contested political boundaries, assumed river courses, and alleged continental shores. The latter can be found in the northern extremities, indicative of the search for the elusive Northwest Passage.
