History

In 1840, José de la Luz Linares received the 4,340-acre (1,760 ha)

Rancho San Jose
to the east, and acquired the rest of Rancho Nogales over the next 10 years.

However, Vejar's luck did not last that long. As time wore on – and particularly as the United States government took over California – Rancho Los Nogales was divided and sold into multiple land ranches, the largest of which was the Diamond Bar Ranch. At the time, it was one of the largest working cattle ranches in the western U.S. The entire Diamond Bar Ranch was acquired by the Transamerica Corporation in the 1950s for the purpose of developing one of the nation's first master-planned communities. Transamerica gave the Diamond Bar name to its new community and incorporated the ranch's familiar diamond and bar cattle brand into various logos (many of which are still in use today).

The first houses in this development were built in 1959, adjacent to the future location of the Pomona Freeway, which was built through the area ten years later.[15] The town's development and population grew extremely quickly after that.

Transamerica oversaw all development of the community through the 1960s. The Transamerica Corporation divested itself of all its real estate ventures in the 1970s and 1980s. As a result, the Diamond Bar project was sold to multiple developers and much of its initial master plan was not implemented during the latter half of its development in the 1980s.

The City of Diamond Bar was incorporated on April 18, 1989.
