Manifest Destiny and the Mexican War

In the 1840s many Americans supported expansion of the American nation.  They believed in a concept known as Manifest Destiny.  Manifest Destiny is the idea that it is the destiny of the United States to expand American democracy and liberty over the entire North American continent, or at least from the Atlantic Ocean to the Pacific Ocean.

In 1846 the United States went to war with Mexico, partly over the issue of annexing Texas.  Texas, once a part of Mexico, had declared its independence as a republic, but wanted to be a part of the United States.  Mexico feared that making Texas a part of the United States would lead to the loss of more Mexican territory in the future.  For many Americans who supported annexation, adding Texas to the United States was a fulfillment of Manifest Destiny.
