It is sometimes incorrectly referred to as Ulster. Ulster is a province of Ireland that includes the 6 counties of Northern Ireland, (Fermanagh, Antrim, Tyrone, Down, Armagh, Derry) and the counties of Donegal, Cavan and Monaghan which are in the Republic of Ireland. It is sometimes referred to as The 6 counties. It is sometimes referred to as the north, with the rest of Ireland being referred to as the south. This is not geographically corrrect as Donegal, one of the other 3 counties of Ulster that is not in Northern Ireland, contains the most northerly point on the island of Ireland.
The counties of Wicklow, and in particular Kildare, are the closest south west of Dublin. Dublin is in the province of Leinster, being one of its 12 counties, and the province in the south west of Ireland is Munster.
Ulster is one of the four historic provinces of Ireland. The province contains nine counties, three of which are in the Irish Republic and the other six are in the United Kingdom. The term 'Ulster' is often used (incorrectly)to describe Northern Ireland. The other three Irish provinces are Connaught, Munster and Leinster.
The Republic of Ireland, is the country made up of 26 of the 32 counties on the island of Ireland. The Republic of Ireland is officially known as Ireland or in the Irish language Éire, according to the Irish constitution. So the names Republic of Ireland and Ireland are used interchangeably. You will see Éire written on Irish stamps and coins.
There are 32 Irish Counties. 26 in the Republic and 6 in the North.
Ireland and Britain joined to become the UK in 1801. 26 counties of Ireland left the union in 1921 and became the Irish Free State (later the Irish Republic) and six Irish counties remained in the union as Northern Ireland.
Ulster is one of the four ancient provinces of Ireland, incorporating counties in the present Irish Republic and province of Northern Ireland. "Planting" refers to the former British government practice of settling Protestants (mostly from Scotland) into the north eastern area of Ireland, with the intention that these Protestants would spread throughout the country and weaken the Catholic influence; it failed as the majority remained in the north east. With the eventual granting of independence to Ireland, the Ulster counties of Antrim, Armagh, Derry, Down, Fermanagh and Tyrone voted to form a new province, called Northern Ireland, whilst the Ulster counties of Cavan, Donegal and Monaghan elected to be part of the Republic. Most of the Protestants in the North erroneously equate the province Northern Ireland with the term "Ulster".
