How did the Mexican-American War shape the future of the United States and Mexico? This book delves into the Mexican-American War (1846-1848), a conflict driven by the U.S. annexation of Texas and territorial disputes between the two countries. It examines the causes of the war, including manifest destiny, the debate over slavery, and the expansionist policies of President James K. Polk. The narrative follows the military campaigns and major battles, such as the capture of Mexico City, and explores the political and social impacts of the war. By analyzing the Treaty of Guadalupe Hidalgo, which ended the conflict, the book discusses the consequences of the war for Mexico, including the loss of vast territories (including present-day California, Arizona, and New Mexico), and how it shaped the future of the United States, particularly in terms of its territorial expansion and the growing tensions over slavery.
