We trace the origins of the Mexican-American War from the Texas Revolution and the annexation debate, through James K. Polk's deliberate provocation of conflict, to the rogue diplomacy of Nicholas Trist, whose defiance of presidential orders ultimately shaped the modern American Southwest. Topics covered: How US settlers in northern Mexico set the stage for Texas independence Why Texas remained unannexed for nearly a decade James K. Polk: the first "dark horse" president and the architect of Manifest Destiny The deliberate start of war \u2014 and Polk's lies to Congress Abraham Lincoln's spot resolutions and the rising anti-war movement The forgotten figure John Hardin and his connection to Lincoln's rise The US occupation of Mexico City and the "All of Mexico" movement Nicholas Trist's defiant negotiation of the Treaty of Guadalupe Hidalgo Why there is no monument in Washington, DC to this war \u2014 and why America forgot it \ud83d\udcda A Wicked War: Polk, Clay, Lincoln and the 1846 U.
