The counties of Ireland are historic administrative divisions of the island. They began as Norman structures, and as the powers exercised by the Cambro-Norman barons and the Old English nobility waned over time, new offices of political control came to be established at a county level. The number of counties varied depending on the time period, however thirty-two is the traditionally accepted and used number.
Ulster is one of the four traditional or historic Irish provinces. It is made up of nine counties: six of these constitute Northern Ireland ; the remaining three are in the Republic of Ireland.
County Antrim is one of the six counties of Northern Ireland, located within the historic province of Ulster. Adjoined to the north-east shore of Lough Neagh, the county covers an area of 3,086 square kilometres (1,192 sq mi) and has a population of 651,321, as of the 2021 census. County Antrim has a population density of 211 people per square kilometre or 546 people per square mile. It is also one of the thirty-two traditional counties of Ireland.
County Londonderry, also known as County Derry, is one of the six counties of Northern Ireland, one of the thirty-two counties of Ireland and one of the nine counties of Ulster. Before the partition of Ireland, it was one of the counties of the Kingdom of Ireland from 1613 onward and then of the United Kingdom after the Acts of Union 1800. Adjoining the north-west shore of Lough Neagh, the county covers an area of 2,118 km2 (818 sq mi) and today has a population of about 252,231.
Carrickfergus is a large town in County Antrim, Northern Ireland. It sits on the north shore of Belfast Lough, 11 miles (18 km) from Belfast. The town had a population of 28,141 at the 2021 census. It is County Antrim's oldest town and one of the oldest towns in Ireland as a whole. Carrickfergus Castle, built in the late 12th century at the behest of Anglo-Norman knight John de Courcy, was the capital of the Earldom of Ulster. After the earldom's collapse, it remained the only English outpost in Ulster for the next four centuries. Carrickfergus was the administrative centre for Carrickfergus Borough Council, before this was amalgamated into the Mid and East Antrim District Council in 2015, and forms part of the Belfast Metropolitan Area. It is also a townland of 65 acres, a civil parish and a barony.
The names of the city and county of Derry or Londonderry in Northern Ireland are the subject of a naming dispute between Irish nationalists and unionists. Generally, although not always, nationalists favour using the name Derry, and unionists Londonderry. Legally, the city and county are called "Londonderry", while the local government district containing the city is called "Derry City and Strabane". The naming debate became particularly politicised at the outset of the Troubles, with the mention of either name acting as a shibboleth used to associate the speaker with one of Northern Ireland's two main communities. The district of Derry and Strabane was created in 2015, subsuming a district created in 1973 with the name "Londonderry", which changed to "Derry" in 1984.
A county corporate or corporate county was a type of subnational division used for the administration of justice in certain towns and cities in England, Wales, and Ireland. They arose when the monarch gave a borough corporation the right to appoint its own sheriffs, separating that borough from the jurisdiction of the sheriff of the county in which it lay.
In Ireland, a barony is a historical subdivision of a county, analogous to the hundreds into which the counties of England were divided. Baronies were created during the Tudor reconquest of Ireland, replacing the earlier cantreds formed after the original Norman invasion. Some early baronies were later subdivided into half baronies with the same standing as full baronies.
Clandeboye or Clannaboy was a kingdom of Gaelic Ireland, comprising what is now south County Antrim, north County Down, and the barony of Loughinsholin. The entity was relatively late in appearance and is associated partly with the Gaelic resurgence of the High Middle Ages. The O'Neill Clandeboy who reigned in the territory descended from Hugh Boy O'Neill, a king of Tyrone. His descendants took advantage of the demise of the Earldom of Ulster during the latter 14th century and seized vast portions of territory. Clandeboye's main seats of power were Shane's Castle and Castle Reagh.
The Local Government (Boundaries) Act 1971 was an Act of the Parliament of Northern Ireland, passed in 1971 to replace the previous system of local authorities established by the Local Government (Ireland) Act 1898. The system was based on the recommendations of the Macrory Report, of June 1970, which presupposed the continued existence of the Government of Northern Ireland to act as a regional-level authority.
The Local Government Act 1972 was an act of the Parliament of Northern Ireland that constituted district councils to administer the twenty-six local government districts created by the Local Government (Boundaries) Act 1971, and abolished the existing local authorities in Northern Ireland.
The Earldom of Ulster was an Anglo-Norman lordship in north-eastern Ireland during the Middle Ages, ruled by the Earls of Ulster and part of the Lordship of Ireland. The Norman knight John de Courcy invaded the Gaelic Irish kingdom of Ulaid in 1177 and conquered most of its territory over the following few years. In 1181 he was made earl palatine of Ulster by Henry II of England. The earldom was the most important Anglo-Norman lordship in the north of Ireland. It covered most of what are now the Ulster counties of Antrim and Down, and briefly extended west to Lough Foyle. Its capital was Carrickfergus Castle.
Ulster railways, present and past, include:
The Route was a medieval territory in Gaelic Ireland, located on the north-east coast of Ulster. It stretched between Coleraine and Ballycastle and as far south as the Clogh River. Originally part of Twescard, a county of the Earldom of Ulster, it was later ruled by the MacQuillans and then the MacDonnells.
Loughinsholin is a barony in County Londonderry, Northern Ireland. Its southeast borders the northwest shore of Lough Neagh, and itself is bordered by seven other baronies: Dungannon Upper to the south; Strabane Upper to the west; Keenaght and Coleraine to the north; Kilconway, Toome Upper, and Toome Lower to the east. It was formed largely on the extent of the northern part of the medieval Irish túath of Uí Tuirtri.
Carrickfergus is a barony in County Antrim, Northern Ireland. It is bounded on the south-east by Belfast Lough, and otherwise surrounded by the barony of Belfast Lower. It is coextensive with the civil parish of Carrickfergus or St Nicholas and corresponds to the former county of the town of Carrickfergus, a county corporate encompassing Carrickfergus town.
