Odo de Bayeux was previously
Earl of Kent and the primary landowner of the region subsequent to his half-brother William the Conqueror's invasion of England in 1066. In 1070, Archbishop
Lanfranc succeeded to the
see of
Canterbury and requested an inquiry into the activities of Odo (and Lanfranc's predecessor,
Stigand) who had allegedly defrauded the
Church (and possibly the
Crown) during his tenure as Earl of Kent. It has subsequently been argued that: "most of the lands had been lost not to Odo, but to
Earl Godwine and his family during
Edward's reign and perhaps even earlier..." and that "Odo had simply succeeded to these encroachments and the conflict between archbishop and earl was to a large extent a reprise of that between
Robert of Jumièges and Godwine in 1051-2," the suggestion being that Lanfranc, despite being the
Prior of a Norman
monastery (and born in
Pavia,
Lombardy), was attempting to restore the pre-conquest landholdings for the
Church of Canterbury. William I determined that the matter should be settled by the nobles of
Kent and ordered that an assembly be formed on
the heath at Penenden (near present-day
Maidstone) for the purpose. William I ordered that the findings of the inquiry or '
trial' of Odo de Bayeux were to be final. Æthelric II in particular had been compelled by William I to attend as the authority on pre-Norman law. Described as: "[A] very old man, very learned in the laws of the land" he was brought by chariot or other carriage to Penenden Heath "in order to discuss and expound these same old legal customs". The presence of a contingent of English (or Saxon) witnesses as experts in ancient laws and customs as well as the French-born representation is regarded as a significant indication of the basis of the Church's claims being grounded in the ancient laws of the land. However it is unclear from the sources which of those laws were cited. Similarly a number of varying transcripts or records of the trial exist and it is unclear which may be regarded as the definitive version of events. The trial of Odo de Bayeux lasted three days and ended in the partial recovery of properties for the church from Odo and others. ==Significance and reliability==
