and Táin Bó Cuailnge March law March law was a set of laws and customs obtaining in the border areas of the Lordship of Ireland during the Middle Ages. These regions were ruled by Anglo-Irish lords between The Pale, which was the portion of Ireland ruled directly by the English crown, and Gaelic Ireland, which was still under the rule of native kings. It came into being in the late 13th century, when King Edward I of England drained resources from Ireland to fund his conquest of Wales and his wars in Scotland. Since the two areas were often intermingled in the border regions, as in the Wicklow Mountains, the applicability and content of march law varied widely.
