Mexican-American War

In this episode, we examine the Mexican-American War, a conflict ignited by the 1845 U.S. annexation of Texas and escalating border disputes that reflected the expansionist ideology of Manifest Destiny. We explore how President James K. Polk justified military action that ultimately carried American forces to Mexico City, while Mexico grappled with internal political instability and the challenges of organizing resistance. The discussion covers major campaigns across Texas, California, and New Mexico, leading to the Treaty of Guadalupe Hidalgo and the sweeping Mexican Cession, through which Mexico relinquished over half its territory in exchange for financial compensation—an outcome that reshaped North America and intensified debates over expansion, power, and national identity in the United States.
