Although schoolhouses had existed in Sacramento County since 1853, Sacramento High School, the city's first secondary education institution, was founded in 1856 and instructed students in courses ranging from core English and mathematics to astronomy and bookkeeping. The high school was moved to a permanent location in 1887 as Sacramento's population started to skyrocket, and the high school administration opened twelve elementary feeder schools across the city of Sacramento. Starting in 1894, in tandem with the early civil rights movement, individual schools in the city began to integrate.
