NORTHERN IRELAND ( Tuaisceart Éireann (Irish) Norlin Airlann (Ulster Scots)

Northern Ireland (Irish: Tuaisceart Éireann; Ulster-Scots: Norlin Airlann) is variously described as a country, province or region which is part of the United Kingdom. Located in the northeast of the island of Ireland, Northern Ireland shares a border to the south and west with the Republic of Ireland. In 2011, its population was 1,810,863, constituting about 30% of the island's total population and about 3% of the UK's population. Established by the Northern Ireland Act 1998 as part of the Good Friday Agreement, the Northern Ireland Assembly (colloquially referred to as Stormont after its location) holds responsibility for a range of devolved policy matters, while other areas are reserved for the British government. Northern Ireland co-operates with the Republic of Ireland in several areas, and the Agreement granted the Republic the ability to "put forward views and proposals" with "determined efforts to resolve disagreements between the two governments". 

On 11 January 2020, legislators in Northern Ireland formed a government for the first time since the Executive of the 5th Northern Ireland Assembly collapsed in January 2017, following the Renewable Heat Incentive scandal. Northern Ireland was created in 1921, when Ireland was partitioned between Northern Ireland and Southern Ireland by the Government of Ireland Act 1920. Unlike Southern Ireland, which would become the Irish Free State in 1922, the majority of Northern Ireland's population were unionists, who wanted to remain within the United Kingdom. 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 151 square miles (391 km²) the largest freshwater lake both on the island of Ireland and in the British Isles. A second extensive lake system is centred on Lower and Upper Lough Erne in Fermanagh. The largest island of Northern Ireland is Rathlin, off the north Antrim coast. Strangford Lough is the largest inlet in the British Isles, covering 150 km² (58 sq mi).

The postage stamps of Ireland are issued by the postal operator of the independent Irish state. Ireland was part of the United Kingdom of Great Britain and Ireland when the world's first postage stamps were issued in 1840. These stamps, and all subsequent British issues, were used in Ireland until the new Irish Government assumed power in 1922. Beginning on 17 February 1922, existing British stamps were overprinted with Irish text to provide some definitives until separate Irish issues became available.^[1] Following the overprints, a regular series of definitive stamps was produced by the new Department of Posts and Telegraphs, using domestic designs. These definitives were issued on 6 December 1922; the first was a 2d stamp, depicting a map of Ireland (including Northern Ireland, which remained a part of the United Kingdom). Since then new images, and additional values as needed, have produced of nine definitive series of different designs.

These were the major stamp productions for everyday use. Commemorative stamps first appeared in 1929, and these now appear several times a year, celebrating many aspects of Irish life, such as notable events and anniversaries, Irish life and culture, and many famous Irish people. Some definitive and commemorative stamps have been produced in miniature sheet, booklet and coil configurations in addition to the common sheet layout. Postage dues and airmails complete the stamp issues of the two, sequential, Irish stamp-issuing authorities. Two styles of watermark were used though the overprinted issues came with the watermarks of the British stamps provided for overprinting by the British Post Office.

This cover I prepared with all 5 Great Britain regional definitive stamps. Years back Royal mail issued Queen's head definitive stamps for different regions with their coat of arm, but now all stamps are issuing without regional difference. The first one from left is England, the Wales, Then Scotland, next is Channel Islands and the last one is N.Ireland. When Channel Islands ( Jersey, Guernsey, Isle of Man) established individual postal systems and separated from Royal Mail, they stopped issuing definitive stamps from the shown series.

This is my third cover from N.Ireland with N.Ireland related stamps. You can see the country name written on them. These covers sent by David from Belfast on July 29, 2015, I received them on August 07, 2015.
