Rosemead is part of a cluster of cities, along with Arcadia, Temple City, Monterey Park, San Marino, and San Gabriel, in the west San Gabriel Valley with a growing Asian population.Prior to the arrival of the Spanish, the area around Rosemead was populated by Native Americans known as the people of the willow houses or better known as the Kizh (pronounced Keech), or as the Spaniards renamed them, the Gabrieleños. In 1771, the Spanish founded the first Mission San Gabriel Arcángel in the area that was formally known as the village of Shevaangna or Siba what is [first Angeleno William McCawley 1996] now known as La Mision Veija or Whittier Narrows on the border between Montebello and Rosemead.
During the Spanish Colonial era, the area that is now the City of Rosemead was part of the land administered by the San Gabriel Mission. As part of the Mexican government’s Secularization Act of 1833, the land, formerly held by the Mission, was distributed to private citizens, requiring only that they build a house and graze cattle, bringing to an end the Mission Era  Following the Mexican–American War and the 1848 signing of the Treaty of Guadalupe which transferred sovereignty over the territory now known as the State of California to the United States, Anglo-American immigration began to flow to the area.
