Question

How did the Mexicans feel about the Gadsden purchase

Answer 1

I’m pretty sure they were fine with all of it since they got a lot of money giving up their land. Plus they could use that money to fix ruined land from native attacks. The only reason I could see them upset is With a great deal of difficulty resulting from the increasing strife between the northern and southern states, the U.S. Senate ratified a revised treaty on April 25, 1854. The new treaty reduced the amount paid to Mexico to $10 million and the land purchased to 29,670 square miles, and removed any mention of Native American attacks and private claims. President Pierce signed the treaty and Gadsden presented the new treaty to Santa Anna, who signed it on June 8, 1854.

After Gadsden’s Purchase a new border dispute caused tension over the United States’ payment, and the treaty failed to resolve the issues surrounding financial claims and border attacks. However, it did create the southern border of the present-day United States, despite the beliefs of the vast majority of policymakers at the time who thought the United States would eventually expand further into Mexico.

They didn’t do what they said they would in the treaty!)

Answer 2

Gadsden's Purchase provided the land necessary for a southern transcontinental railroad and attempted to resolve conflicts that lingered after the Mexican-American War. ... In 1853, Mexican officials evicted Americans from their property in the disputed Mesilla Valley.
