Leinster in the context of "River Shannon"

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.

Ireland is an island in Northern Europe, in the north Atlantic Ocean. The island measures about 480 km (300 mi) north-south, and 275 km (171 mi) east-west, with a total area of 84,421 km (32,595 sq mi). It lies about 53°N 8°W / 53°N 8°W / 53; -8, near the western edge of the European continental shelf, part of the Eurasian Plate. Ireland is separated from the island of Great Britain by the Irish Sea to the east, and from mainland Europe by the Celtic Sea to the south. It is bounded to the north by the North Channel and to the south by St George's Channel. Ireland is the second-largest landmass in the British Isles, after Great Britain and before Lewis and Harris.

Its main geographical features include low central plains surrounded by coastal mountains. The highest peak is Carrauntoohil (Irish: Corrán Tuathail), which is 1,039 metres (3,409 ft) above sea level. The western coastline is rugged, with many islands, peninsulas, headlands and bays, while the southern and northern coasts have a smaller number of substantial sea inlets, such as Lough Foyle and Cork Harbour; no part of the land is more than around 110 km (68 mi) from the sea. The island is almost bisected by the River Shannon, which at 360.5 km (224 mi) with a 102.1 km (63 mi) estuary is the longest river in Ireland and flows south from County Cavan in the province of Ulster to form the boundary between Connacht and Leinster, and later Munster, and meet the Atlantic just south and west of Limerick. Lough Neagh is the largest of several sizeable lakes along Ireland's rivers.

Dublin is the capital and largest city of Ireland. Situated on Dublin Bay at the mouth of the River Liffey, it is in the province of Leinster, and is bordered on the south by the Dublin Mountains, part of the Wicklow Mountains range. Dublin is the largest city by population on the island of Ireland; at the 2022 census, the city council area had a population of 592,713, while the city including suburbs had a population of 1,263,219, County Dublin had a population of 1,501,500. Various definitions of a metropolitan Greater Dublin Area exist.

A settlement was established in the area by the Gaels during or before the 7th century, followed by the Vikings. As the Kingdom of Dublin grew, it became Ireland's principal settlement by the 12th century Anglo-Norman invasion of Ireland. Dublin expanded rapidly from the 17th century and was briefly the second largest in the British Empire and sixth largest in Western Europe after the Acts of Union in 1800. Following independence in 1922, Dublin became the capital of the Irish Free State, renamed Ireland in 1937. As of 2018, Dublin was listed by the Globalization and World Cities Research Network (GaWC) as a global city, with a ranking of "Alpha minus", which placed it among the top thirty cities in the world.

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 Parliament of Ireland (Irish: Parlaimint na hÉireann) was the legislature of the Lordship of Ireland, and later the Kingdom of Ireland, from 1297 until the end of 1800. It was modelled on the Parliament of England and from 1537 comprised two chambers: the House of Commons and the House of Lords. The Lords were members of the Irish peerage ('lords temporal') and bishops ('lords spiritual'; after the Reformation, Church of Ireland bishops). The Commons was directly elected, albeit on a very restricted franchise. Parliaments met at various places in Leinster and Munster, but latterly always in Dublin: in Christ Church Cathedral (15th century), Dublin Castle (to 1649), Chichester House (1661–1727), the Blue Coat School (1729–31), and finally a purpose-built Parliament House on College Green.

The main purpose of parliament was to approve taxes that were then levied by and for the Dublin Castle administration. Those who would pay the bulk of taxation, namely the clergy, merchants, and landowners, also comprised the members. Only the "English of Ireland" were represented until the first Gaelic lords were summoned during the 16th-century Tudor reconquest. Under Poynings' Law of 1495, all Acts of Parliament had to be pre-approved by the Irish Privy Council and English Privy Council. Parliament supported the Irish Reformation and Catholics were excluded from membership and voting in penal times. The Constitution of 1782 amended Poynings' Law to allow the Irish Parliament to initiate legislation. Catholics were re-enfranchised under the Roman Catholic Relief Act 1793.

This article lists some of the attested Gaelic kingdoms of early medieval Ireland prior to the Norman invasion of 1169-72.

For much of this period, the island was divided into numerous clan territories and kingdoms (known as túatha). These túatha often competed for control of resources and thus they continually grew and shrank (in both size and number). In addition to kingdoms or túatha, Gaelic Ireland was also divided into five prime overkingdoms (Old Irish cóiceda, Modern Irish cúige). These were Ulaid (in the north), Connacht (in the west), Laighin (in the southeast), Mumhan (in the south) and Mide (in the centre).

There are four provinces of Ireland: Connacht, Leinster, Munster and Ulster. The Irish word for this territorial division, cúige, meaning "fifth part", suggests that there were once five, and at times Meath has been considered to be the fifth province. In the medieval period, however, there were often more than five. The number of provinces and their delineation fluctuated until 1610, when they were permanently set by the administration of James I. The provinces of Ireland no longer serve administrative or political purposes but function as historical and cultural entities.
