The Spanish Empire established its rule in the Californias in 1769. During this time, the Californias encompassed a massive territorial expanse, including both Alta California (present day U.S. state of California) and Baja California (present day Mexican states of Baja California and Baja California Sur), which were governed under a military administration led by the Governor of the Californias. In 1804, the Californias were officially divided into two administrations: Alta California, based in Monterey, and Baja California, based in Loreto.
