Founded as a Viking settlement, the Kingdom became Ireland’s principal city following the Norman invasion. The city expanded rapidly from the 17th century and was briefly the second largest city in the British Empire before the Act of Union in 1800. Following the partition of Ireland in 1922, it became the capital of the Irish Free State, later renamed Ireland.
The city celebrated its ‘official’ millennium in 1988 AD, meaning that the Irish government recognised 988 AD as the year in which the city was settled and that this first settlement would later become the city of Dublin.

It is bordered by a low mountain range to the south and surrounded by flat farmland to the north and west.The Liffey divides the city in two between the Northside and the Southside.
