Wilmot Proviso Is Introduced

Former President John Quincy Adams also expressed his belief that the war was fundamentally an effort to expand slavery in a speech he gave before the House on May 25, 1846. In response to such concerns, Democratic Congressman David Wilmot introduced the Wilmot Proviso, which aimed to prohibit slavery in any new territory acquired from Mexico. Wilmot's proposal did not pass Congress, but it spurred further hostility between the factions.
