Westminster is a city in northern Orange County, California known for its many Vietnamese refugees who immigrated to the city during the 1980s. They settled largely in Little Saigon, and the city is known as the "capital" of overseas Vietnamese with 36,058 Vietnamese Americans and at 40.2% (2010), the highest municipal prevalence of Vietnamese Americans. Westminster was founded in 1870 by Rev. Lemuel Webber as a Presbyterian temperance colony and was incorporated in 1957.
