It was discovered in 1542 and was integrated into the territories of the Viceroyalty of the New Spain (as Mexico was formerly known when it was a colony of Spain). When Mexico won its war of independence against Spain in 1821, California also became part of Mexico on that date and continued to be a territory of Mexico until the Mexican-American War. At the end of such conflict in 1848, the Treaty of Guadalupe-Hidalgo ceded such territories to the US.
