In the late-nineteenth and early-twentieth century, many Chinese residing in the United States were transnational migrants who kept close connections to their families in China by sending remittances, writing letters, and making temporary visits to the home village; transnational institutions also developed, which helped move money, information, and goods across the Pacific. Chinese diaspora archaeology is ripe to contribute to scholarship on transnationalism because of its attention to materiality, but few scholars have adopted a transnational framework or conducted research on Chinese migrants’ home villages. A research project that investigates the formation three diasporically linked sites—a new home village in south China and the second iteration of two Chinatowns in southern California—is a first attempt at examining the materiality of Chinese transnationalism on both sides of the Pacific. Chinese diaspora archaeology can also gain from understanding these transnationally connected communities in their current status as heritage sites.
