The Conquest of California, also known as the Conquest of Alta California or the California Campaign, was an important military campaign of the Mexican–American War carried out by the United States in Alta California, then a part of Mexico. The conquest lasted from 1846 into 1847, until military leaders from both the Californios and Americans signed the Treaty of Cahuenga, which ended the conflict in California.
