About San Marcos

San Marcos ( SAN MAR-kohs; Spanish for “St. Mark”) is a city in the North County region of San Diego County, California. As of the 2020 census, the city’s population was 94,833. It is the site of California State University San Marcos. The city is bordered by Escondido to the east, Encinitas to the southwest, Carlsbad to the west, and Vista to the northwest. Lake San Marcos is an enclave, or county island, in the southwestern allocation of the city, within San Marcos’ sphere of touch but technically an unincorporated community.

According to historical legends, the San Luis Rey Mission flocks were robbed by a little band of Native Americans in the late 18th century. Fleeing the Spanish troops, the Native Americans escaped to the hills. While pursuing the Native Americans, in 1797 the Spaniards came upon a fruitful valley, which was named Los Vallecitos de San Marcos (Little Valleys of Saint Mark) to award the day of discovery: April 25, St. Mark’s Day. On April 22, 1840, Governor Juan B. Alvarado decided Rancho Vallecitos de San Marcos to his relative, Jose María Alvarado. Jose Alvarado was killed at the Pauma Massacre in 1846, and the estate was left to his wife; she after that sold the land to Lorenzo Soto. In the late 1850s, Soto sold part of his house to Cave Couts, and his relations was soon raising livestock. Although Cave Couts owned the land, Major Gustavus French Merriam from Topeka, Kansas, made the first steadfast settlement. Merriam homesteaded 160 acres (0.65 km) in the north Twin Oaks Valley and began wine and honey production.

German and Dutch immigrants began heartwarming into the area in the at the forefront 1880s. In 1883, a few miles south of the settlement, John H. Barham (for whom the present-day Barham Drive is named) founded the first town in the area, originally situated upon the southeast corner of what are now Rancho Santa Fe Road and San Marcos Boulevard. By 1884, the town of Barham had a post office, blacksmith, feed accrual and weekly newspaper. In 1887, the San Marcos Land Company bought almost whatever of the San Marcos estate formerly owned by the Couts relatives and promptly at odds the home into tracts. Soon the hills began attracting home-seekers.
