In the early 1840s a map of North America would show two dominant nations, the United States and Mexico. As the decade progressed, tensions between the two countries steadily mounted, erupting violently in the spring of 1846. What followed was a passionate territorial battle that would last for two years, cover hundreds of thousands of square miles, and forever alter the communities in its wake.

The U.S. - Mexican War paints a detailed, cross-cultural portrait of the events that changed the face of the North American continent. A chronicle of voices and memorabilia - including personal diaries, letters, photographs, and artwork from both sides - The U.S.-Mexican War is the companion to the powerful four-hour public television documentary of the same name, produced by KERA in Dallas.
