Which state was NOT part of the territorial changes resulting from the Treaty of Guadalupe Hidalgo?

The Treaty of Guadalupe Hidalgo, signed in 1848, marked the conclusion of the Mexican-American War and led to significant territorial changes for the United States. It resulted in the cession of a vast portion of Mexico's northern territories, which included present-day California, Texas, Arizona, New Mexico, Nevada, and parts of Colorado and Utah.

New Jersey did not experience any territorial changes as a result of this treaty, as it was not located in the territories contested between the U.S. and Mexico during the war. The states that were part of the territorial changes were those that had been originally claimed by Mexico and changed hands due to the treaty. Understanding the historical context of these territorial negotiations helps clarify why New Jersey is the state that did not participate in these significant alterations delineated by the treaty.
