History: 

The area that is now Brentwood was part of the Rancho San Vicente y Santa Monica, a Spanish land-grant ranch sold off in pieces to Anglos after the Mexican-American War. The area now popularly known as Brentwood began following the establishment of the large 600-acre Pacific Branch of the National Home for Disabled Soldiers and Sailors in the 1880s. The economic growth stimulated by this veterans facility led to immediate property development outside its west gate. The community of 'Westgate' was annexed on  June 14, 1916. Westgate was the city's 17th annexation, and added another 50 square miles to the city of Los Angeles, including large parts of what is now the Pacific Palisades and a small portion of today's Bel-Air. (Note: There is a Westgate Avenue in West Los Angeles/Brentwood that remembers the original name of the district.)

Originally an agricultural district (soybeans and avocados) Brentwood is now one of the wealthiest neighborhoods in Los Angeles, and one of the prominent districts of the Westside.
