History of Long Beach

In 1784 the Spanish Empire's King Carlos III granted Rancho Los Nietos to Spanish soldier Manuel Nieto. The Rancho Los Cerritos and Rancho Los Alamitos were divided from this territory. The boundary between the two ranchos ran through the center of Signal Hill on a southwest to northeast diagonal. A portion of western Long Beach was originally part of the Rancho San Pedro. Its boundaries were in dispute for years, due to flooding changing the Los Angeles River boundary, between the ranchos of Juan Jose Dominguez and Manuel Nieto.

In 1843 Jonathan Temple bought Rancho Los Cerritos, after arriving in California in 1827 from New England. He built what is now known as the "Los Cerritos Ranch House", an adobe which still stands and is a National Historic Landmark. Temple created a thriving cattle ranch and prospered, becoming the wealthiest man in Los Angeles County. Both Temple and his ranch house played important local roles in the Mexican-American War. On an island in the San Pedro Bay, Mormon pioneers made an abortive attempt to establish a colony (as part of Brigham Young's plan to establish a continuous chain of settlements from the Pacific to Salt Lake).

In 1866 Temple sold Rancho Los Cerritos for $20,000 to the Northern California sheep-raising firm of Flint, Bixby & Co, which consisted of brothers Thomas and Benjamin Flint and their cousin Lewellyn Bixby. Two years previous Flint, Bixby & Co had also purchased along with Northern California associate James Irvine, three ranchos which would later become the city that bears Irvine's name. To manage Rancho Los Cerritos, the company selected Lewellyn's brother Jotham Bixby, the "Father of Long Beach". Three years later Bixby bought into the property and
