The Treaty of Cahuenga, also called the "Capitulation of Cahuenga," ended the fighting of the Mexican-American War in Alta California in 1847. It was not a formal treaty between nations but an informal agreement between rival military forces in which the Californios gave up fighting. The treaty was drafted in English and Spanish by José Antonio Carrillo, approved by American Lieutenant-Colonel John C. Frémont and Mexican Governor Andrés Pico on January 13, 1847 at Campo de Cahuenga in what is now North Hollywood, Los Angeles, California.
