Ireland is a country in north-western Europe. The modern sovereign state occupies about five-sixths of the island of Ireland, which was first partitioned on May 3, 1921. It is bordered by Northern Ireland (part of the United Kingdom) to the north, by the Atlantic Ocean to the west, by the Irish Sea to the east and by the Celtic Sea and St George’s Channel to the South and South-East. Legally, the term Republic of Ireland (Irish: Poblacht na hÉireann) is the description of the State but Ireland is its name.
