Counties of Ireland in the context of "County Sligo"

Ireland (Irish: Éire [ˈeːɾʲə] ), also known as the Republic of Ireland (Poblacht na hÉireann), is a country in Northwestern Europe. It consists of 26 of the 32 counties of the island of Ireland, with a population of about 5.4 million. Its capital and largest city is Dublin, on the eastern side of the island, with a population of over 1.5 million. The sovereign state shares its only land border with Northern Ireland, which is part of the United Kingdom. It is otherwise surrounded by the Atlantic Ocean, with the Celtic Sea to the south, St George's Channel to the south-east and the Irish Sea to the east. It is a unitary, parliamentary republic. The legislature, the Oireachtas, consists of a lower house, Dáil Éireann; an upper house, Seanad Éireann; and an elected president (Uachtarán) who serves as the largely ceremonial head of state, but with some important powers and duties. The head of government is the Taoiseach (prime minister, lit. 'chief'), elected by the Dáil and appointed by the president, who appoints other government ministers.

The Irish Free State was created with Dominion status in 1922, following the Anglo-Irish Treaty. In 1937, a new constitution was adopted, in which the state was named "Ireland" and effectively became a republic, with an elected non-executive president. It was officially declared a republic in 1949, following The Republic of Ireland Act 1948. Ireland became a member of the United Nations in 1955. It joined the European Communities (EC), the predecessor of the European Union (EU), in 1973. The state had no formal relations with Northern Ireland for most of the 20th century, but the 1980s and 1990s saw the British and Irish governments working with Northern Irish parties to resolve the conflict that had become known as the Troubles. Since the signing of the Good Friday Agreement in 1998, the Irish government and Northern Irish government have co-operated on a number of policy areas under the North/South Ministerial Council created by the Agreement.

The Irish Free State (6 December 1922 – 29 December 1937), also known by its Irish name Saorstát Éireann (English: /ˌsɛərstɑːt ˈɛərən/ SAIR-staht AIR-ən, Irish: [ˈsˠiːɾˠsˠt̪ˠaːt̪ˠ ˈeːɾʲən̪ˠ]), was a state established in December 1922 under the Anglo-Irish Treaty of December 1921. The treaty ended the three-year Irish War of Independence between the forces of the Irish Republic—the Irish Republican Army (IRA)—and British Crown forces.

The Free State was established as a dominion of the British Empire. It comprised 26 of the 32 counties of Ireland. Northern Ireland, which was made up of the remaining six counties, exercised its right under the Treaty to opt out of the new state. The Irish Free State government consisted of the governor-general—the viceregal representative of the King—and the Executive Council (cabinet), which replaced both the revolutionary Dáil Government and the Provisional Government set up under the Treaty. W. T. Cosgrave, who had led both of these administrations since August 1922, became the first president of the Executive Council (prime minister). The Oireachtas or legislature consisted of Dáil Éireann (the lower house) and Seanad Éireann (the upper house), also known as the Senate. Members of the Dáil were required to take an Oath of Allegiance to the Constitution of the Free State and to declare fidelity to the King. The oath was a key issue for opponents of the Treaty, who refused to take it and therefore did not take their seats. Pro-Treaty members, who formed Cumann na nGaedheal in 1923, held an effective majority in the Dáil from 1922 to 1927 and thereafter ruled as a minority government until 1932.

Northern Ireland is divided into six counties, namely Antrim, Armagh, Down, Fermanagh, Londonderry and Tyrone. Six largely rural administrative counties based on these were among the eight primary local government areas of Northern Ireland from its 1921 creation until 1973. The other two local government areas were the urban county boroughs of Derry (geographically part of the County of Londonderry) and Belfast (geographically split between the counties of Antrim and Down).

The six counties date from the Kingdom of Ireland; five were created between 1570 and 1591 in the Tudor conquest of Ireland, while county Londonderry dates from 1613 and the Plantation of Ulster. The total number of counties in the island of Ireland is 32, with Northern Ireland and the Republic of Ireland often respectively called "the Six Counties" and "the Twenty-Six Counties", especially by Irish nationalists opposed to the partition of Ireland. The 1898–1973 administrative counties were subdivided into county districts. The two-tier county/district system was replaced with a single-tier of "districts", numbering 26 in 1973 and rationalised into 11 in 2015. The areas corresponding to the six counties and two county boroughs remain in use for some administrative purposes, and the six historic counties retain a popular identity.

Southern Ireland (Irish: Deisceart Éireann, pronounced [dʲɛʃcəɾˠt̪ˠ ˈeːɾʲən̪ˠ]) was the larger of the two parts of Ireland that were created when Ireland was partitioned by the Government of Ireland Act 1920. It comprised 26 of the 32 counties of Ireland or about five-sixths of the area of the island, whilst the remaining six counties, which occupied most of Ulster in the north of the island, formed Northern Ireland.

The Act of 1920, which became effective on 3 May 1921, was intended to create two self-governing territories within Ireland, each with its own parliament and governmental institutions, and both remaining within the United Kingdom of Great Britain and Ireland. It also contained provisions for co-operation between the two territories and for the eventual reunification of Ireland. However, in the 1921 elections for Southern Ireland's House of Commons, Sinn Féin candidates won 124 of the 128 seats (all candidates were unopposed and no actual polling occurred), and ignored the parliament, assembling instead as the Second Dáil. The House of Commons of Southern Ireland—consisting of the four unionist members—met only once, while the Senate only met twice. Continuing unrest resulted in the Anglo-Irish Treaty and the Provisional Government, which administered Southern Ireland from 16 January 1922 to 5 December 1922: effectively a transitional administration for the period between the ratifying of the Anglo-Irish Treaty and the establishment of the Irish Free State. Its legitimacy was disputed by the Anti-Treaty delegates to Dáil Éireann.

Ulster (/ˈʌlstər/; Irish: Ulaidh [ˈʊlˠiː, ˈʊlˠə] or Cúige Uladh [ˌkuːɟə ˈʊlˠə, - ˈʊlˠuː]; Ulster Scots: Ulstèr or Ulster) is one of the four historical provinces of Ireland, located in the northern part of the island. It is made up of nine counties, with six of these comprising Northern Ireland (a part of the United Kingdom), while the remaining three are in the Republic of Ireland.

It is the second-largest (after Munster) and second-most populous (after Leinster) of Ireland's four traditional provinces, with Belfast being its biggest city. Unlike the other provinces, Ulster has a high percentage of Protestants, making up almost half of its population. English is the main language and Ulster English the main dialect. A minority also speak Irish, and there are Gaeltachtaí (Irish-speaking regions) in County Donegal which is home to a quarter of the total Gaeltacht population of the Republic of Ireland. There are also large Irish-speaking networks in southern County Londonderry and in the Gaeltacht Quarter, Belfast. Ulster-Scots is also spoken extensively in the counties Antrim, Down, Londonderry, Tyrone and Donegal. Lough Neagh, in the east, is the largest lake in the British Isles, while Lough Erne in the west is one of its largest lake networks. The main mountain ranges are the Mournes, Sperrins, Blue Stack (Croaghgorms) and Derryveagh Mountains.

Plantations in 16th- and 17th-century Ireland (Irish: Plandálacha na hÉireann) involved the confiscation of Irish-owned land by the English Crown and the colonisation of this land with settlers from Great Britain.

The main plantations took place from the 1550s to the 1620s, the biggest of which was the plantation of Ulster. The plantations led to the founding of many towns, massive demographic, cultural and economic changes, changes in land ownership and the landscape, and also to centuries of ethnic and sectarian conflict.

Munster (Irish: an Mhumhain [ə ˈwuːnʲ] or Cúige Mumhan [ˌkuːɟə ˈmˠuːnˠ]) is the largest of the four provinces of Ireland, located in the south west of the island. In early Ireland, the Kingdom of Munster was one of the kingdoms of Gaelic Ireland ruled by a "king of over-kings" (Irish: rí ruirech). Following the Norman invasion of Ireland, the ancient kingdoms were shired into counties for administrative and judicial purposes. In later centuries, local government legislation has seen further sub-division of the historic counties.

Munster has no official function for local government purposes. For the purposes of the ISO, the province is listed as one of the provincial sub-divisions of the State (ISO 3166-2:IE) and coded as "IE-M". Munster covers an area of 24,675 km (9,527 sq mi). Its population was 1,373,346 in 2022, with Cork being the largest city. Other significant urban centres in the province include Limerick and Waterford.

County Kilkenny (Irish: Contae Chill Chainnigh) is a county in Ireland. It is in the province of Leinster and is part of the Southern Region. It is named after the city of Kilkenny. Kilkenny County Council is the local authority for the county. At the 2022 census the population of the county was 103,685. The county was based on the historic Gaelic kingdom of Ossory (Osraighe), which was coterminous with the Diocese of Ossory.

The Irish Republic (Irish: Poblacht na hÉireann or Saorstát Éireann) was a revolutionary state that declared its independence from the United Kingdom of Great Britain and Ireland in January 1919. The Republic claimed jurisdiction over the whole island of Ireland, but by 1920 its functional control was limited to only 21 of Ireland's 32 counties, and British state forces maintained a presence across much of the north-east, as well as Cork, Dublin and other major towns. The republic was strongest in rural areas, and through its military forces was able to influence the population in urban areas that it did not directly control.

Its origins date back to the Easter Rising of 1916, when Irish republicans seized key locations in Dublin and proclaimed an Irish Republic. The rebellion was crushed, but the survivors united under a reformed Sinn Féin party to campaign for a republic. In the 1918 United Kingdom general election, the party won a clear majority of the constituencies in Ireland; in many seats Sinn Féin candidates did not face meaningful opposition. The Sinn Féin winners did not take their seats in the U.K. parliament, but instead gathered in Dublin on 21 January 1919 to form the first Dáil (legislature) of Ireland. Republicans then established a government, a court system and a police force. At the same time, the Irish Volunteers, who came under the control of the Dáil and became known as the Irish Republican Army, fought against British state forces in the Irish War of Independence.
