County Louth in the context of "Airgíalla"

Ulster Irish (endonym: Gaeilg Uladh or Irish: Gaeilic Uladh, Standard Irish: Gaeilge Uladh) is the variety of Irish spoken in the province of Ulster. It has much in common with Scottish Gaelic and Manx. Within Ulster there have historically been two main sub-dialects: West Ulster and East Ulster. The Western dialect is spoken in parts of County Donegal and was once spoken in parts of neighbouring counties, hence the name 'Donegal Irish'. The Eastern dialect was spoken in most of the rest of Ulster and northern parts of counties Louth and Meath.

Carlingford Lough (Irish: Loch Cairlinn, Ulster Scots: Carlinford Loch) is a glacial fjord or sea inlet in northeastern Ireland, forming part of the border between Northern Ireland to the north and the Republic of Ireland to the south. On its northern shore is County Down, the Mourne Mountains, and the town of Warrenpoint; on its southern shore is County Louth, the Cooley Mountains and the village of Carlingford. The Newry River flows into the loch from the northwest.

County Armagh (Irish: Contae Ard Mhacha [ˌaːɾˠd̪ˠ ˈwaxə]) is one of the six counties of Northern Ireland and one of the traditional thirty-two counties of Ireland. It is located in the province of Ulster and adjoins the southern shore of Lough Neagh. It borders the Northern Irish counties of Tyrone to the west and Down to the east. The county borders Louth and Monaghan to the south and southwest, which are in the Republic of Ireland. It is named after its county town, Armagh, which derives from the Irish Ard Mhacha, meaning "Macha's height". Macha was a sovereignty goddess in Irish mythology and is said to have been buried on a wooded hill around which the town of Armagh grew. County Armagh is colloquially known as the "Orchard County" because of its many apple orchards.

The county covers an area of 1,327 km (512 sq mi), making it the smallest of Northern Ireland's six counties by size and the sixth-smallest county on the island of Ireland. With a population of 194,394 as of the 2021 census, it is the fourth-most populous county in both Northern Ireland and Ulster. It is the 10th most populous of Ireland's 32 traditional counties, as well as the fifth-most densely populated. In addition to the city of Armagh and the western portion of the city of Newry, notable towns in the county include Lurgan, Portadown and Craigavon.

County Down (Irish: Contae an Dúin) is one of the six counties of Northern Ireland, one of the nine counties of Ulster and one of the traditional thirty-two counties of Ireland. It covers an area of 961 sq mi (2,490 km) and has a population of 552,261. It borders County Antrim to the north, the Irish Sea to the east, County Armagh to the west, and County Louth across Carlingford Lough to the southwest.

In the east of the county is Strangford Lough and the Ards Peninsula. The largest settlement is Bangor, a city on the northeast coast. Three other large towns and cities are on its border: Newry lies on the western border with County Armagh. Lisburn and Belfast lie on the northern border with County Antrim. Down contains the southernmost point of Northern Ireland (Cranfield Point) and the easternmost point of Ireland (Burr Point).

The River Boyne (Irish: An Bhóinn or Abhainn na Bóinne) is a river which flows through Leinster, Ireland. The course of the river is about 112 kilometres (70 mi) long. It rises at Eidenderry, near Offaly and flows north-east through County Offaly, County Kildare, and County Meath to reach the Irish Sea between Mornington, County Meath, and Baltray, County Louth.

County Meath (/miːð/ MEEDH; Irish: Contae na Mí or simply an Mhí, lit. 'middle') is a county in the Eastern and Midland Region of Ireland, within the province of Leinster. It is bordered by County Dublin to the southeast, Louth to the northeast, Kildare to the south, Offaly to the southwest, Westmeath to the west, Cavan to the northwest, and Monaghan to the north. To the east, Meath also borders the Irish Sea along a narrow strip between the rivers Boyne and Delvin, giving it the second shortest coastline of any county. Meath County Council is the local authority for the county.

Meath is the 14th-largest of Ireland's 32 traditional counties by land area, and the 8th-most populous, with a total population of 220,826 according to the 2022 census. The county town and largest settlement in Meath is Navan, located in the centre of the county along the River Boyne. Other towns in the county include Trim, Kells, Laytown, Ashbourne, Dunboyne, Slane and Bettystown.

Meath (/miːð/ MEEDH; Modern Irish: Mí; Old Irish: Mide [ˈmʲiðʲe]) was a kingdom in Ireland from the 1st to the 12th century AD. Its name means "middle," denoting its location in the middle of the island.

At its greatest extent, it included all of County Meath (which takes its name from the kingdom), all of County Westmeath, and parts of counties Cavan, Dublin, Kildare, Longford, Louth and Offaly.

Muiredach's High Cross is a high cross from the 10th or possibly 9th century, located at the ruined monastic site of Monasterboice, in County Louth, Ireland. There are two other high crosses at Monasterboice; in local terms Muiredach's cross is also known as the South Cross. Muiredach's cross is the most impressive surviving example of early medieval Irish stonework, and the crosses at Monasterboice have been said to be Ireland's greatest contribution to European sculpture.

Edward Bruce, Earl of Carrick (Norman French: Edward de Brus; Middle Irish: Edubard a Briuis; Modern Scottish Gaelic: Scottish Gaelic: Eideard or Iomhair Bruis; c. 1280 – 14 October 1318), was a younger brother of Robert the Bruce, King of Scots. He supported his brother in the 1306–1314 struggle for the Scottish crown, then pursued his own claims in Ireland. Proclaimed High King of Ireland in 1315 and crowned in 1316, he was eventually defeated and killed by Anglo-Irish forces of the Lordship of Ireland at the Battle of Faughart in County Louth in 1318.
