Since its very beginning, archaeology has in many senses always related to a much wider constituency than just archaeologists. This relationship between archaeology and the public has often been overlooked and constantly changes. Public archaeology, as a field of research and practice, has been developing since the 1970s in English-speaking countries, particularly in the United States, Britain, and Australia, and is today beginning to spread to other parts of the world. Global expansion of public archaeology comes with the recognition of the need for a careful understanding of local contexts, particularly the culture and socio-political climate.
