The Atlas of Hillforts of Britain and Ireland project (2012-2016) compiled a massive database on hillforts by a team drawn from the Universities of Oxford, Edinburgh and Cork. This volume outlines the history of the project, offers preliminary assessments of the online digital Atlas and presents initial research studies using Atlas data.

This book tracks the development of social complexity in Ireland from the late prehistoric period on into the Middle Ages. Using a range of methods and techniques, particularly data from settlement patterns, Blair Gibson demonstrates how Ireland evolved from constellations of chiefdoms into a political entity bearing the characteristics of a rudimentary state. This book argues that early medieval Ireland's highly complex political systems should be viewed as amalgams of chiefdoms with democratic procedures for choosing leaders rather than kingdoms. Gibson explores how these chiefdom confederacies eventually transformed into recognizable states over a period of 1,400 years.

This is the first project to study hillforts in relation to warfare and conflict in Bronze Age Ireland. This project combines remote sensing and GIS-based landscape analysis with conventional archaeological survey to investigate ten prehistoric hillforts across southern Ireland.
