The Mexican-American War (1846-1848)-Introduction

The Mexican-American War lasted from 1846 to 1848. The official cause of the war was Mexican opposition to the American annexation of the Republic of Texas, which had won its freedom from Mexico ten years earlier. However, President James Polk intended to use the war to greatly expand the United States by annexing New Mexico and California, therefore it was the first war fought against a fellow republic to gain territory.
