Many large cities in the United States and around the world have an ethnic area called Chinatown. Each was settled by people who came from China. For example, Chinatown in San Francisco, California, began in the 1840s. Gold had been discovered in California. Chinese immigrants came to America in search of wealth. They settled in an area later became known as Chinatown. Nearly all the immigrants were man. Their hard work was quickly recognized. In 1850, San Francisco Mayor John Geary held a ceremony honoring Chinese efforts to improve the city. Today, Chinatown is a leading cultural influence in San Francisco. Many people visit the area. Chinatown were also established in cities in the western states of Oregon and Washington during the middle of the 19th century. Many Chinese settlers in these areas helped build the first railroad system across the United States. However, after the work ended in 1869, many Chinese moved to the eastern and middle parts of the United States. The first Chinese immigrants arrived in Chicago, Illinois, in the 1870s. Many of these first immigrants opened clotrehes cleaning businesses and low cost eating places. Chicagos Chinatown has grown over the years. The largest number of immigrants came after communists took control of mainland China in 1948. Chinatowns can also be found in the cities outside the United States. For example, the first Chinese settlers in London arrived in the late 18th century. They were men who worked for the East India Company. Later Chinese immigrants operated small stores and eating places that were visited by Chinese sailors traveling through the city. Today many people visit Londons Chinatown.
