Proposed by David Wilmot:
Prohibit slavery in the new territory

Attached the proviso to an appropriations bill to pay Mexico for land. Congress House of Representatives:
Majority Northeners
So, approved appropriations bill and proviso on August 8, 1846.
February 1, 1847
Approved bill, rejected proviso.
The proviso never went into effect. Northern vs. Southern States Senators vote by region
Northern and Southern states want balance between slave and free states
Congress stuck: neither side had majority, bill could not be sent to president Effects and Opinions of the Proviso Caused more conflict over slavery
further divided North and South
Other people that would have been affected by the proviso feared economic competition from slave owners Treaty of Guadalupe Hidalgo When: February 2, 1848
Where: Guadalupe Hidalgo.

Native people: deemed heathens
