The
Home Nations refers collectively to
England,
Scotland,
Wales, and
Northern Ireland (
countries of the United Kingdom), and in certain sports (e.g.
Rugby football) contexts, to England, Scotland, Wales and the whole island of
Ireland. The term "Home Nations" is used in this second sense partly because Northern Ireland and the
Republic of Ireland have a unified association structure in certain sports, such as the
Irish Rugby Football Union. Formerly the phrase was applied in general in this same wider sense, such as the period between 1800 and 1922, before the political partition of
Ireland, when the whole island was part of the United Kingdom. The term
home countries (not to be confused with the "
home counties") is also sometimes used, and is synonymous.
