Thousands of Chinese came to Stockton from the Kwangtung province of China during the 1850s due to a combination of political and economic unrest in China and the discovery of gold in California. After the gold rush, many worked for the railroads and land reclamation projects in the Sacramento–San Joaquin River Delta and remained in Stockton. By 1880 Stockton was home to the third-largest Chinese community in California. Discriminatory laws, in particular the Chinese Exclusion Act of 1882, restricted immigration and prevented the Chinese from buying property. The Lincoln Hotel, built in 1920 by the Wong brothers on South El Dorado Street, was considered one of Stockton's finest hotels of the time. Only after the Magnuson Act was repealed in 1962 were American-born Chinese allowed to buy property and own buildings.
