Why did the Mexican Cession result in renewed sectional tension about the Missouri Compromise?
Answers
The "Mexican Cession" refers to lands surrendered to the United States by Mexico at the end of the Mexican war. The leading National political issues related to the extending slavery. After the Mexican wars, Mexico lost an enormous part of its territory was a tremendous embarrassment and created anger among many citizens.
Under the terms of Cession, the states of California, Nevada, Utah and Arizona added by the Gadsden Treaty in 1853. They get many more dollars to cover the claims of American citizens against Mexico.
Tensions increased because both North and South sides saw that land as an opportunity to gain more states that would be free or have slaves. So California was admitted as a free state which required Northernes to help capture slaves that had escaped to the North.
