Dublin (/ˈdʌblᵻn/, Irish: Baile Átha Cliath [blʲaːˈklʲiəh]) is the capital and largest city of Ireland. Dublin is in the province of Leinster on Ireland's east coast, at the mouth of the River Liffey. The city has an urban area population of 1,345,402. The population of the Greater Dublin Area, as of 2016, was 1,904,806 people. Founded as a Viking settlement, the Kingdom of Dublin 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 Acts of Union in 1800. Following the partition of Ireland in 1922, Dublin became the capital of the Irish Free State, later renamed Ireland.
Dublin is situated at the mouth of the River Liffey and encompasses a land area of approximately 115 square kilometres (44 sq mi) in east-central Ireland. 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. Each of these is further divided by two lesser rivers – the River Tolka running southeast into Dubin Bay, and the River Dodder running northeast to the mouth of the Liffey. Two further water bodies – the Grand Canal on the southside and the Royal Canal on the northside – ring the inner city on their way from the west and the River Shannon. The River Liffey bends at Leixlip from a northeasterly route to a predominantly eastward direction, and this point also marks the transition to urban development from more agricultural land usage.
