context_page_description: County Meath is a county in Ireland. It is in the province of Leinster and is part of the Mid-East Region. It is named after the historic Kingdom of Meath. Meath County Council is the local authority for the county. At the 2016 census, the population of the county was 195,044. The county town of Meath is Navan. Other towns in the county include Trim, Kells, Laytown, Ashbourne, Dunboyne, and Slane.
  It is one of only two counties outside the west of Ireland to have an official Gaeltacht and the only county in Leinster to have an official Gaeltacht.
context_section_description: Due to a lack of extensive written historical records prior to the 5th century AD, the early history of Meath is murky and largely mythologised. Irish legend purports that the title of "High King of Ireland" stretches back millennia, however it is today known that the Hill of Tara did not become a seat of power until the early centuries AD. In the 400s, Niall of the Nine Hostages, King of the Uí Néill, conquered southward from Ulster and established a kingdom in Meath. As was commonplace in Ireland at the time, the achievements of Niall and his sons were propagandised and mythicised by bards to such an extent that much of what is known about them is considered fictional. Nevertheless, the dynasty of the Uí Néill had become firmly established in the centre of Ireland and they proclaimed themselves the Kings of Tara and Kings of Uisnech. The Uí Néill dynasty subsequently divided into two septs, the Northern Uí Néill who remained in Ulster, and the Southern Uí Néill who now ruled over several small, disjointed kingdoms established throughout modern-day Meath, Westmeath and Dublin. 
  Following the split, a series of internecine conflicts erupted between members of the Uí Néill septs. The feud was eventually resolved, and as part of the resolution it was decided that the position of King of Tara would alternate between the northern and southern Uí Néill septs. The title alternated between the two septs for over 500 years, with every second king traveling south from Ulster for an inauguration ceremony at Tara. By 740, Domnall Midi of the Clann Cholmáin dynasty, the most powerful branch of the southern Uí Néill, had conquered or subdued all neighboring clans in Meath, and the Uí Néill were recognised as their suzerain. Domnall was now in possession of both Tara, the seat of the Uí Néill, and the Hill of Uisneach, which held symbolic significance as the geographical centre of Ireland. Having secured his power in the heart of the island, Domnall now presided over a unified Kingdom of Mide (Meath), a name derived from the Old Irish meaning "middle".
  The first annalistic mention of a "High King of Ireland" or "Ard-Rí" was Máel Sechnaill mac Máele Ruanaid, King of Mide, who died in 862 AD, having achieved many victories against both the Norse and the kingdoms of Ulster. Later historians would retroactively apply the title of "High King" to the earlier Kings of Tara, although there were no contemporary references to either the Kings of Tara or Mide being referred to as Ard-Rí prior to the 9th century. During the reign of Máel Sechnaill mac Domnaill in the 970s, the fort of Dun-na-Scia near Lough Ennell became the permanent royal residence, thereby creating two seats of power within the kingdom - one for the High King and one for the King of Mide. 
  In the late 10th century, the Dalcassians to the south, led by Brian Boru, consolidated their hold over Munster, with Boru establishing himself as King of Munster. The ascendancy of this longtime rival kingdom posed a serious threat to High King Máel Sechnaill mac Domnaill, so the two leaders met at Clonfert in 997 and agreed upon a truce, whereby Boru was granted overlordship of the southern half of the island. The Kingdom of Leinster immediately rebelled against Boru and allied with the Norse Kingdom of Dublin. Mide and Munster formed a defensive alliance and, after a series of campaigns throughout 998–999, crushed the forces of Leinster and Dublin, which both became vassals of Munster. 
  Boru now believed that Munster was the most powerful kingdom in Ireland and therefore he, and not Máel Sechnaill, should be High-King. Máel Sechnaill's claim to the kingship was challenged by Boru in 1002 at the Hill of Tara. The Meath king requested a month-long truce to rally his subordinates to his side, which Boru accepted, however Máel Sechnaill was quickly abandoned by his northern Uí Néill kinsmen. Having failed to raise enough troops to challenge Boru, he was forced to abdicate, thus ending the hereditary right of the Uí Néill to the title of High King. Although they remained Kings of Meath, the po
