Baja California is Mexico's northwesternmost state, a 1,300 km-long borderland running from the busiest land border crossing on earth at Tijuana down the Pacific coast to the cactus deserts of the Valle de los Cirios. It packs a world-class wine valley, Baja Med cuisine, Pacific surf beaches, a 3,000 m granite sierra and the warm Sea of Cortez into a single drive-friendly state.
Baja California's story is short on empires and long on frontiers. The peninsula was home to the Kumiai, Paipai, Kiliwa and Cucapa in the north and the Cochimi further south for at least 10,000 years, leaving rock art at El Vallecito and Catavina but no cities. Spanish contact came in the 1530s and settlement only in 1697, when Jesuits began the mission chain in the south; Dominicans pushed north from 1773, founding the last missions of the Californias at Santo Tomas and, in 1834, in the valley now known as Guadalupe. The Treaty of Guadalupe Hidalgo cut the Californias in two in 1848, leaving the north with a border rather than a capital. Everything modern grew from that line: Mexicali was founded in 1903 by Colorado River irrigation and built largely by Cantonese labourers; Tijuana boomed on American Prohibition from 1920, with the Agua Caliente casino drawing Hollywood; Russian Molokans planted the Guadalupe valley's first commercial vines from 1905. Baja California became Mexico's 29th state in 1952, industrialised through the maquiladora programme from the 1960s, and in 1989 elected the first opposition state governor in modern Mexican history.
