Formed in 1967, the Society for Historical Archaeology (SHA) is the largest scholarly group concerned with the archaeology of the modern world (A.D. 1400-present). The main focus of the society is the era since the beginning of European exploration. The society is specifically concerned with the identification, excavation, interpretation, and conservation of sites and materials on land and underwater. Geographically the society emphasizes the New World, but also includes European exploration and settlement in Africa, Asia, and Oceania.
