nAraidi in what was Dál Fiatach territory, it was one of the main monastic foundations in Ireland. Condaire (modern Irish: Coinnire, meaning "[wild-]dog oak-wood"), now known as Connor in County Antrim. It was the chief church of the Dál nAraidi located in the minor-kingdom of Dál Sailni, and was founded by St. Mac Nisse. It would become the cathedral for the diocese of Connor. Airther Maigi (modern Irish: Oirthear Maí, meaning "the east of the plain"), now known as Armoy in County Antrim. It was the chief church of the Dál Riata founded by St. Olcan; however, after Dál nAraidi expansion in the 7th century it lost its episcopal status and was superseded by the church of Connor. Droma Móir (modern Irish: Droim Mór, meaning "big ridge"), now known as Dromore in County Down. It became the chief church of the Uí Echach Cobo, and was founded circa 510 by St. Colmán. It would become the cathedral for the diocese of Dromore. Artefacts Although Francis John Byrne describes the few La Tène artefacts discovered in Ireland as 'rather scanty', most of the artefacts (mostly weapons and harness pieces) have been found in the north of Ireland, suggesting 'small bands of settlers (warriors and metalworkers) arrived' from Britain in the 3rd century BC, and may have been absorbed into the Ulaid population. Kingdoms, dynasties, and septs By the 12th century Ulaid was divided into four main dynastic sub-kingdoms, each consisting of smaller petty-kingdoms: Dál Fiatach, an Ulaid people based at Dún De Lethglaise (present-day Downpatrick, County Down), who dominated the over-kingship of Ulaid and had interests in the Isle of Man. Their principal sept were the Mac Duinnshléibhe. Dál nAraidi a Cruithin people, dominated by the Dál nAraidi of Magh Line based at Ráith Mór (near present-day Antrim town, County Antrim). They were the Dál Fiatach's main challengers for the over-kingship. Their principal sept were the Uí Choelbad. Uí Echach Cobo, a Cruithin sept, kin with the Dál nAraidi, who also challenged for the over-kingship of Ulaid. They were based in modern-day County Down, possibly at Cnoc Uí Echach (Knock Iveagh). Their principal sept were the Mag Aonghusa; Uí Tuirtri, originating from Airgíalla they took control of most of Dál nAraidi's territory. Its principal sept was the Uí Fhloinn. In the 10th-century revision of the Lebor na Cert, the following twelve Ulaid petty-kingdoms are given as paying stipends to the king
