Background and detail
Background. In 1769, Visitador General José de Gálvez organized an expedition under Junípero Serra and Gaspar de Portolà to found missions and presidios at San Diego and Monterey, securing Spain's claim to Pacific coast harbors recommended by Cabrillo and Vizcaino. Serra had been appointed president of the Baja California missions in 1767.
Arrival at San Diego. The Portolá/Serra party trekked 900 miles (1,400 km) from Loreto, suffering dwindling food supplies, and arrived in San Diego on July 1, 1769. Serra described the reunion of the land and sea parties as a day of great rejoicing, with each group sharing accounts of the hardships they had endured.
Founding Ceremony. On July 16, 1769, Serra founded the mission in honor of Didacus of Alcalá, establishing it in a simple shelter on Presidio Hill that served as a temporary church. The site lay in an area long inhabited by the Kumeyaay people, in present-day San Diego, California.
Significance and Early Activity. Mission San Diego de Alcalá was the first of the 21 California missions, though the Portolá expedition's arrival preceded the founding ceremony. The first vineyards planted in California were planted at the mission in 1769, marking an early agricultural activity at the new establishment.
