On December 10, the Treaty of Paris officially ends the Spanish American War. Spain cedes Puerto Rico, Guam, and the Philippines to the U.S. Cuba becomes a U.S. Protectorate.
The Mexican War ends on February 2, with the signing of the Treaty of Guadalupe Hidalgo. That agreement gives the United States jurisdiction over nearly half of what was Mexico including the current states of California, New Mexico, Arizona, Nevada, Utah and part of Colorado.
