The Spanish began colonizing
Alta California with the
Portolá expedition of 1769–1770. The two-pronged Portolá effort involved both a long sea voyage against prevailing winds and the
California Current, and a difficult land route from Baja California. Colonies were established at
San Diego and
Monterey, with a
presidio and Franciscan
mission at each location. A more direct land route and further colonization were desired, especially at present-day
San Francisco, which Portolá saw but was not able to colonize. By the time of de Anza's expedition, three more missions had been established, including
Mission San Antonio de Padua west of the
Salinas Valley. In 1772, de Anza proposed an expedition to Alta California to the
Viceroy of New Spain. This was approved by the
King of Spain and on January 8, 1774, with 3 padres, 20 soldiers, 11 servants, 35 mules, 65 cattle, and 140 horses, Anza set forth from
Tubac Presidio, south of present-day
Tucson, Arizona. de Anza heard of a California Native American called Sebastian Tarabal who had fled from
Mission San Gabriel to Sonora, and took him as guide. The expedition took a southern route along the
Rio Altar (
Sonora y Sinaloa, New Spain), then paralleled the present-day Mexico–California border, crossing the
Colorado River at its confluence with the
Gila River. This was in the domain of the
Yuma tribe, with which he established good relations. de Anza reached
Mission San Gabriel Arcángel, near the California coast, on March 22, 1774, and
Monterey, California, Alta California's future capital (Alta California split from Las Californias 1804, creating Baja and Alta), on April 19. He returned to Tubac by late May 1774. This expedition was closely watched by
Viceroy and King, and on October 2, 1774, de Anza was promoted to the rank of
lieutenant-colonel, and ordered to lead a group of colonists to Alta California. The Spanish were desirous of reinforcing their presence in Alta California as a buffer against
Russian colonization of the Americas advancing from the north, and possibly establish a harbor that would give shelter to Spanish ships. The expedition got under way on October 23, 1775, and arrived at
Mission San Gabriel Arcángel in January 1776, the colonists having suffered greatly from the winter weather en route. The expedition continued on to Monterey with the colonists. Having fulfilled his mission from the Viceroy, he continued north with the priest
Pedro Font and a party of twelve others, following an inland route to the
San Francisco Bay established in 1770 by
Pedro Fages. On the way, he led a raid on Apache settlements near
Presidio San Ignacio de Tubac, capturing forty Apaches. The soldiers divided the captives among them as slaves; de Anza kept the fifteen female captives and their newborns as his share. In de Anza's diary on March 25, 1776, he states that he "arrived at the arroyo of
San Joseph Cupertino (now
Stevens Creek), which is useful only for travelers. Here we halted for the night, having come eight leagues in seven and a half hours. From this place we have seen at our right the estuary which runs from the port of San Francisco." Pressing on, Bautista de Anza located the sites for the
Presidio of San Francisco and
Mission San Francisco de Asis in present-day
San Francisco, California on March 28, 1776. He did not establish the settlement; it was established later by
José Joaquín Moraga. While returning to Monterey, he located the original sites for
Mission Santa Clara de Asis and the town of San José de Guadalupe (present-day
San Jose, California), but again did not establish either settlement. Today this route is marked as the
Juan Bautista de Anza National Historic Trail. Despite de Anza's successes, Spanish ambitions to establish a permanent overland route from Sonora to Alta California were thwarted in 1781, when a revolt of the
Yumas tribe closed the trail at the
Yuma Crossing of the Colorado River. The route was not reopened until the late 1820s, and the only regular travel to Alta California during the intervening years was by sea. ==Governor of New Mexico==
