War With Mexico
1846
President James K. Polk, with his mind set of manifest destiny wanted to claim the territory of California, New Mexico, and part of Texas (of the people).When Mexico did want to sell it to him he got mad and declared war. Once theses new territories were conquered by the U.S the question of slavery came up once again. The north believed the war was an attempt for the south to get more slave territory and were proven right when Polk signed the Treaty of Guadalupe Hidalgo; which provided new territory south of the 36/30 line to become slave territories (of the people).
