Dublin (Irish: Baile Átha Cliath) is the capital and largest city in Ireland, near the midpoint of Ireland's east coast, at the mouth of the River Liffey and at the centre of the Dublin Region. Founded as a centre of Viking settlement, the city has been Ireland's capital since mediæval times.
A person from Dublin is known as a Dubliner or colloquially as a Dub, or, pejoratively, a Jackeen.
