Diego de Borica was a Spanish explorer and the seventh governor of Las Californias from 1794 to 1800,[1] and is credited with defining Alta- and Baja-California's official borders.[2]


As the governor, Diego de Borica and Father Fermín Lasuén determined that five more missions were needed in 1795 along El Camino Real.[3] Borica sent expeditions from four different missions to find suitable new settlements that were no more than one day's travel as military escorts were necessary.[4] By August 1796, Borica notified Viceroy Miguel de la Grúa Talamanca that no increase in troops was necessary. The first missionary site selected in 1796 was Mission San José near the pueblo of the same name.[3]

In 1795, Borica gave José Darío Argüello a Spanish land grant known as Rancho de las Pulgas. This rancho was the largest grant on the San Francisco Peninsula spanning 35,260 acres (14,270 ha).[5]

In 1797, Borica ordered the construction of a battery to protect the cove east of Point Medanos. The location initially was named "Bateria San Jose" and was chosen because the promontory overlooked San Francisco Bay and Alcatraz Island. Borica provisioned the unit with five brass cannons.[6]

On orders from Viceroy La Grúa Talamanca, Borica established a school grounds at the center of Villa de Branciforte in 1797. Also in 1797, he granted José María Verdugo's retirement.[7] Verdugo was the grantee of Rancho San Rafael.

Before stepping down as governor, Borica recommended reappointing José Joaquín de Arrillaga to organize military defenses for California.[2]
