Viscounty of Léon

The Viscounty or County of Léon (Breton: Kontelezh Leon) was a feudal state in extreme western Brittany in the High Middle Ages. Though nominally a vassal of the sovereign duke of Brittany, Léon was functionally independent of any external controls until the viscounts came under attack by King Henry II of England. It thus became the focus of revolts and wars when Brittany was drawn into the Angevin empire.

The history of Léon's early counts is obscure. The original viscounts of Léon were public officials appointed by the counts of Cornouaille, but by the mid-eleventh century they had usurped public authority in their province. Their ability to remain independent of both count and duke was likely due to their remoteness in the extremity of the Armorican peninsula. Unlike their Breton neighbours they did not participate in the Norman conquest of England in 1066. Count Harvey II, however, did participate on the side of Stephen of Blois in the nineteen years of civil war in England called The Anarchy.

The viscounts also fought with the duke of Brittany in attempts to maintain their independence. Henry II had ordered Duke Conan IV of Brittany to march against Léon. Conan IV's son-in-law and eventual successor, Henry II's son, Geoffrey II, went to war against Viscount Guihomar IV of Léon. In the course of these wars most of the castles of the viscounts of Léon were razed and Guihomar's lands—his source of revenue—were significantly reduced. These conflict over authority in Léon continued down to the reign of John II.

In 1235 the subvassals of Léon and Penthièvre brought a series of complaints, the Communes petitiones Britonum, against the duke, Peter of Dreux, to King Louis IX of France. They claimed that the viscounts of Léon had never theretofore been subject to the custody of or relief from the duke nor had they been required to seek permission for the construction of fortresses. They had always had the right of wreck, that is, a monopoly on shipwrecks and their cargoes on the coasts. They had the right to draw up testaments and to dispense with alms and make arrangements for debt-payment freely. The duke, they said, did not have a right to exact oaths of homage from the viscount's men and the viscount had the right of placitum spade ("pleas of the sword"). The right of wreck alone yielded 100,000 solidi per annum in revenues from a single rock on the treacherous coast, which an earlier viscount, Guihomar IV, had called his "most precious stone."

The territory of Léon was preserved in the Bishopric of Léon. It is now part of the department of Finistère. One place within the former viscounty that continues to preserve many examples of medieval architecture, such as the church of Notre Dame du Kreisker, is the town of Saint-Pol-de-Léon.
