By 1870, the area had few remaining indigenous inhabitants. These were new infectious diseases to them. As more non-natives arrived and established settlements, diseases that were endemic among them caused high mortality among the Tongva and other indigenous peoples. Because the language of the Tongva was different from the neighboring tribes, the Spanish called them "Gabrielino". When the explorer Juan Rodríguez Cabrillo arrived off the shores of Santa Catalina in 1542, he was met by the Tongva people. The Tongva occupied much of the Los Angeles basin and the southern Channel Islands - Santa Catalina, San Nicolas, San Clemente and Santa Barbara. Historic occupants of the land along the Rio Hondo River were the indigenous Tongva (also known as Gabrielino), a portion of the Uto-Aztecan family of Native Americans. History A large portion of Montebello was originally part of Rancho Paso de Bartolo, acquired in 1847 by Pío Pico, the last Governor of Alta California.

It is considered part of the Gateway Cities, and is a member of the Gateway Cities Council of Governments.
