UCI was one of three new UC campuses established in the 1960s to accommodate growing enrollments across the UC system. A site in Orange County was identified in 1959, and in the following year the Irvine Company sold the University of California 1,000 acres (400 ha) of land for one dollar to establish the new campus. President Lyndon B. Johnson dedicated the campus in 1964.
