A pressure group and membership organization representing a Trust for British Archaeology formed in 1971 by amateur and professional archaeologists as an expression of their concern at the massive erosion of Britain's archaeological heritage. The aim was to increase public awareness of the accelerating destruction of the archaeological heritage and campaign for better funding and infrastructure for archaeological investigations. In these matters the organization achieved considerable success and by 1973/4 the government had increased four-fold the budget available for rescue archaeology in England.
