Trivia: Gold was discovered in California just days before the end of what war?
Mexican-American War
Civil War
War of 1812
Spanish-American War
The correct answer is Mexican-American War
So why is this answer correct? : The California Gold Rush officially began on January 24, 1848, when carpenter James W. Marshall was building a sawmill and spotted gold near Sutter Creek. A week later, Mexico ceded California to the U.S. as part of the Treaty of Guadalupe Hidalgo, ending the Mexican-American War. Within two years, California became an official state thanks to the gold rush population boom.
