Introduction
Throughout the 20th century there were many notable developments in Irish archaeology, both academically and administratively. Already by the middle of the century considerable change had taken place, that was a time when new attitudes and initiatives were underway. It was also a time of economic development and social adjustments in the wake of World War II. The changes that took place in archaeology during the following half-century were extensive and varied and involved most aspects of the subject. The year 1950 is, therefore, a reasonable starting-point for commencing this review but this does not imply that a new and altered archaeology had emerged. On the contrary established personnel and institutions continued to play a major role, while some longstanding research projects continued. What is offered in this paper is a brief historical review largely considered from the academic point of view, it is selective and is not intended to provide detailed information about all aspects of research and other developments that have taken place over the past half-century. However, an attempt will be made to review the causes and influences that brought about such developments, but it is not a potted history, neither is it a review of intellectual developments.
