Northern Ireland was covered by an ice sheet for most of the last ice age and on numerous previous occasions, the legacy of which can be seen in the extensive coverage of drumlins in Counties Fermanagh, Armagh, Antrim and particularly Down. The centrepiece of Northern Ireland's geography is Lough Neagh, at 392 km² the largest freshwater lake in the British Isles. A second extensive lake system is centred on Lower and Upper Lough Erne in Fermanagh.

In a number of areas, the island operates officially as a single entity, for example, in sport. The major religions, the Roman Catholic Church, the Church of Ireland and the Presbyterian Church of Ireland, are organised on an all-island basis. 92% of the population of the Republic of Ireland are Roman Catholic, and 40% in Northern Ireland. Some trades unions are also organised on an all-Irish basis and associated with the Irish Congress of Trades Unions (ICTU) in Dublin, while others in Northern Ireland are affiliated with the Trades Union Congress (TUC) in the United Kingdom. The island also has a shared culture across the divide in many other ways. Traditional Irish music, for example, though showing some variance in all geographical areas, is broadly speaking the same on both sides of the border. Irish and Scottish traditional music are similar.

A number of political parties are represented in the Dáil and coalition governments are common. Neither of the two largest parties, Fianna Fáil and Fine Gael, strongly identifies itself as either a left or right-wing group. The third largest party in the state is the centre-left Labour Party. Labour is joined on the left by the Green Party, Sinn Féin and the Socialist Party. The right is represented by the Progressive Democrats who, while liberal on economic policy, are left-wing on social matters. Independent TDs (MPs) also play an important role in Irish politics.

In 1998, following a Provisional IRA cease-fire, the Good Friday Agreement was concluded and attempts began to be made to restore self-government to Northern Ireland on the basis of power sharing between the two communities. Violence has greatly decreased since the signing of the accord.

Chinese and Urdu are also spoken by Northern Ireland's Asian communities. According to the most recent census returns, Chinese is now the second most widely spoken language, though the 8000-strong Chinese community — while often referred to as the "third largest" community in Northern Ireland — is tiny by international standards.

The state operates under the Constitution of Ireland, also known as Bunreacht na hÉireann, adopted in 1937. The constitution falls broadly within the liberal democratic tradition. It defines the organs of government and guarantees certain fundamental rights. The constitution may only be amended by referendum. Important constitutional referenda have concerned issues such as abortion, the status of the Catholic Church, divorce and the European Union.

There are many references to food and drink in early Irish literature. Honey seems to have been widely eaten and used in the making of mead. The old stories also contain many references to banquets, although these may well be greatly exaggerated and provide little insight to every diet. There are also many references to fulacht fiadh. These were sites for cooking deer, and consisted of holes in the ground which were filled with water. The meat was placed in the water and cooked by the introduction of hot stones. Many fulacht fiadh sites have been identified across the island of Ireland, and some of them appear to have been in use up to the 17th century.

The parliament of the Republic of Ireland is the Oireachtas. The Oireachtas consists of the President and two houses: Dáil Éireann and Seanad Éireann (also known as the Senate). The Dáil is by far the dominant tier of the legislature. The President may not veto laws in most circumstances and the Senate may only delay legislation.
