Map of Texas, California and Oregon 1846

Wonderful map by Samuel Augustus Mitchell of 1846. Published in Philadelphia. This was one of the many maps attributed to Mitchell whose School Atlas published from 1845 to 1857 had a great influence on American cartography. The map was drawn in the last days before the eruption of war between Mexico and the United States and shows the three regions of utmost concern to the citizens of the United States. The Republic of Texas had been founded ten years before by American ex-patriots and there were many Americans also in California and the Oregon Country. The Mexicans were in form control of California and the British were active in Oregon. Many in the United States desired that all three territories be incorporated into the United States.
