Mide originally referred to the area around the Hill of Uisneach in County Westmeath, where the festival of Beltaine was celebrated. The larger province of Meath, between the Irish Sea and the Shannon, is traditionally said to have been created by Túathal Techtmar, an exemplar king, in the first century from parts of the other four provinces. In the fourth and fifth centuries its territories were taken over by the Uí Néill from Connacht and they pushed out Laigin tribes. The Uí Néill assumed the ancient titles of Kings of Uisnech in Mide and Kings of Tara in Brega and claimed a cattle-tribute, the Bóroma Laigen, on the Laigin. The Uí Failge, under Failge Berraide, were finally expelled from the plain of Mide with the battle of Druim Derg in 514. The Uí Enechglaiss were an early paramount dynasty of the Laigin. An ogham stone found south of Slane suggests they controlled the Brega area in County Meath together with Carbury Hill and the plains of Kildare. During the early 6th century, they were expelled across the Wicklow Mountains.
