In 2003, the discovery in Irish peat bogs of two well-preserved Iron Age bodies provided an opportunity to undertake detailed scientific analysis with a view to understanding how, when, and why the two young male victims were killed and their bodies consigned to the bogs. Research also looked at other Iron Age objects deposited ritually in peat bogs, including other bog bodies. The locations at which the bodies were discovered were researched and a wealth of historical, folklore, and mythological material was consulted to assist interpretation of the finds. A theory was developed that appears to explain not only the ritual killings in question but also the deposition of bog bodies and other objects in peat bogs in proximity to significant territorial boundaries. The theory links the bog bodies with kingship and sovereignty rituals during the Iron Age.
