Montebello, California, is a city located in Los Angeles County, just east of downtown Los Angeles. The area was originally inhabited by the Tongva Native American tribe before Spanish settlers arrived in the late 18th century. The land was part of the Rancho La Merced grant, which was later divided and sold to various settlers. In the early 20th century, the discovery of oil in the area led to a boom in population and economic growth. Montebello was officially incorporated as a city in 1920. Throughout the 20th century, the city continued to grow and diversify, with an influx of immigrants from various countries, including Mexico, Japan, and Armenia. Today, Montebello is a vibrant, multicultural city with a rich history and a strong sense of community.
