Dublin dates from 841 when the Vikings made a permanent settlement. The name Dublin comes from dubh linn or black pool which refers to the deep pool formed where the Poddle stream meets the River Liffey near modern day Dublin Castle. The Irish name for the city is Baile Átha Cliath which means the "Town of the ford of the hurdles".
In 1169 the Norman Invasion was led by Strongbow who conquered Dublin and declared himself King of Leinster. This led to King Henry II pronouncing himself Lord of Ireland. Dublin Castle was built in 1204 and became the centre of English power in Ireland. During the Tudor times Dublin enjoyed prominence as the centre of administrative rule in Ireland and Trinity College was established. During the Georgian period Dublin became the second city of the British Empire and the Fifth largest City in Europe - buildings such as the Four Courts and the Custom House date from this time. Dublin declined in the 19th century following the Act of Union 1800 which moved the seat of government back to Westminster.
In the early 20th century the 1916 Easter Rising, War of Independence and Civil War all resulted in the destruction of central Dublin. On 21st January 1919 the first Dáil of Ireland was convened in the Mansion House and the Declaration of Independence was passed. Dublin was declared the Capital City of the Irish Free State and in 1949 the Capital of the Republic of Ireland.
