No. In 1707 England and Wales joined with Scotland to form the United Kingdom. The three countries are on the island that is sometimes referred to as Great Britain. Ireland is a separate island. In 1801, Ireland became part of the United Kingdom, but obviously not Great Britain as it was still a separate island.

Edinburgh and London - where the respective parliaments were.
In 1707 England and Scotland signed the Act of Union whereby they agreed to unite to create a new country to be called Great Britain with the parliament based in London and a shared monarch. In 1800 Ireland joined the union to form the United Kingdom of Great Britain and Ireland. In 1920 Ireland split into Northern Ireland and Southern Ireland and Southern Ireland left the United Kingdom in 1922 to become a separate country again.
England did not unite with Northern Ireland. Ireland was at one time part of the British empire. Ireland, England, Scotland and Wales became the United Kingdom in 1801. In 1922, the Republic of Ireland became independent and Northern Ireland was formed and remained in the United Kingdom.
There are only three countries in Britain but four in the United Kingdom. Wales became affiliated to England in 1285. The Parliaments of England and Scotland merged in 1707 to become the United Kingdom of Great Britain. Ireland joined the group in 1801 and it became the United Kingdom of Great Britain and Ireland. In 1921, most of Ireland withdrew from the UK and became independent again. The current full name of the country, as recognised at the United Nations, is 'The United Kingdom of Great Britain and Northern Ireland' and its citizens are British in international law although people will often describe themselves as being English, Scottish, Welsh or Irish as the case may be.

The Kingdom of England and the Kingdom of Ireland officially united on July 2, 1800. The Union is now known as the United Kingdom.
Wales and England have always been part of Great Britain, as Great Britain is an island and not a country, whereas the UK is a country. Wales and England were together under the Romans, but became separate countries during the Middle Ages. In 1282, Wales was annexed by England and wasn't really treated as being separate part to England until the 1950s.
The term Britain was derived from the Roman - Brittania, the name for the Island containing modern England Wales and Scotland. As Angles Saxons Jutes Norse etc invaded the Island the native population of Britons was either assimilated or pushed outwards. Part of this movement was the displacement of some Britons to what is now a region of France - Brittany. Greater Britain (Britannia Major) was first used to distinguish the mainland island from Lesser Britain (Britannia Minor) or Brittany by Geoffrey of Monmouth in his Historia Regum Britannia (1136). The term "Great Britain" was first used officially in 1474 in a marriage proposal between Edward IV of England and James (son of James III of Scotland) "this Nobill Isle, callit Gret Britanee". It was next used formally when the Kingdoms of Scotland and England merged under King James VI and I who proclaimed himself as 'King of Great Brittaine, France and Ireland' in 1604 but politically it was not until the Union of the Parliaments in 1707 that the title Great Britain was used. Note It should be noted that Great Britain only refers to the mainland Island and not to Ireland. The "United Kingdom of Great Britain and Ireland" was the full title from 1801 until 1922 when it became the "United Kingdom of Great Britain and Northern Ireland" when the Irish Free State was formed (now Eire or Ireland). The UK or British refers to all four countries (England Wales Scotland and Northern Ireland). Geographically the British Isles refers to both Islands including all of Ireland (north and south). Answer the term was first used as a political expression in 1547 when Henry V111 wanted to Unite England and Scotland under one crown. The Scots were not impressed.
There is a trade union in Ireland called Unite. See the link below.
