Dublin (; locally ; , or Áth Cliath, , occasionally Duibhlinn) is the capital and most populous city of Ireland. The English name for the city is derived from the Irish name Dubhlinn, meaning "black pool". Dublin is situated in the province of Leinster near the midpoint of Ireland's east coast, at the mouth of the River Liffey and the centre of the Dublin Region.
Founded as a Viking settlement, it evolved into the Kingdom of Dublin and became the island's principal city following the Norman invasion. The city expanded rapidly from the 17th century; it was briefly the second largest city in the British Empire and the fifth largest in Europe. Dublin entered a period of stagnation following the Act of Union of 1800, but it remained the economic centre for most of the island. Following the partition of Ireland in 1922, the new parliament, the Oireachtas, was located in Leinster House. Dublin became the capital of the Irish Free State and later the Republic of Ireland.
Like the cities of Cork, Limerick, Galway and Waterford, Dublin is administered separately from its respective County with its own City Council. The city is listed by the Globalization and World Cities Research Network (GaWC) as a global city, with a ranking of "Alpha-", placing Dublin among the top 30 cities in the world. It is a historical and contemporary cultural centre for the country, as well as a modern centre of education, the arts, administration, economy, and industry.
Although the area of Dublin Bay has been inhabited by humans since prehistoric times, the writings of Ptolemy (the Egyptian astronomer and cartographer) in about 140 AD provide possibly the earliest reference to a settlement there. He called the settlement .
The name Dublin comes from the Irish name Dubhlinn or Duibhlinn, meaning "black pool". This is made up of the elements dubh (black) and linn (pool). In most Irish dialects, dubh is pronounced . The original pronunciation is preserved in the names for the city in other languages such as Old English Difelin, Old Norse Dyflin, modern Icelandic Dyflinn and modern Manx Divlyn. Other localities in Ireland also bear the name Duibhlinn, variously anglicized as Devlin, Divlin and Difflin. Historically, scribes using the Gaelic script wrote bh with a dot over the b, rendering or . Those without knowledge of Irish omitted the dot, spelling the name as Dublin.
, meaning "town of the hurdled ford", is the common name for the city in modern Irish. is a place name referring to a fording point of the River Liffey near Father Mathew Bridge. was an early Christian monastery, believed to have been in the area of Aungier Street, currently occupied by Whitefriar Street Carmelite Church.
The subsequent Scandinavian settlement centred on the River Poddle, a tributary of the Liffey in an area now known as Wood Quay. The Dubhlinn was a small lake used to moor ships; the Poddle connected the lake with the Liffey. This lake was covered during the early 18th century as the city grew. The Dubhlinn lay where the Castle Garden is now located, opposite the Chester Beatty Library in Dublin Castle. Táin Bó Cuailgne ("The Cattle Raid of Cooley") refers to Dublind rissa ratter Áth Cliath, meaning "Dublin, which is called Ath Cliath".
Dublin was established as a Viking settlement in the 9th century and, despite a number of rebellions by the native Irish, it remained largely under Viking control until the Norman invasion of Ireland was launched from Wales in 1169. The King of Leinster, Diarmait Mac Murchada, enlisted the help of Strongbow, the Earl of Pembroke, to conquer Dublin. Following Mac Murrough's death, Strongbow declared himself King of Leinster after gaining control of the city. In response to Strongbow's successful invasion, King Henry II of England reaffirmed his sovereignty by mounting a larger invasion in 1171 and pronounced himself Lord of Ireland. Around this time, the county of the City of Dublin was established along with certain liberties adjacent to the city proper. This continued down to 1840 when the Barony of Dublin City was separated from the Barony of Dublin. Since 2001, both baronies have been redesignated the City of Dublin.
Dublin Castle, which became the centre of Norman power in Ireland, was founded in 1204 as a major defensive work on the orders of King John of England. Following the appointment of the first Lord Mayor of Dublin in 1229, the city expanded and had a population of 8,000 by the end of the 13th century. Dublin prospered as a trade centre, despite an attempt by King Robert I of Scotland to capture the city in 1317. It remained a relatively small walled medieval town during the 14th century and was under constant threat from the surrounding native clans. In 1348, the Black Death, a lethal plague which had ravaged Europe, took hold in Dublin and killed thousands over the following decade.
Dublin was incorporated into the English Crown as the Pale, which was a narrow strip of English settlement along the eastern seaboard. The Tudor conquest of Ireland in the 16th century spelt a new era for Dublin, with the city enjoying a renewed prominence as the centre of administrative rule in Ireland. Determined to make Dublin a Protestant city, Queen Elizabeth I of England established Trinity College in 1592 as a solely Protestant university and ordered that the Catholic St. Patrick's and Christ Church cathedrals be converted to Protestant.
The city had a population of 21,000 in 1640 before a plague in 1649–51 wiped out almost half of the city's inhabitants. However, the city prospered again soon after as a result of the wool and linen trade with England, reaching a population of over 50,000 in 1700.
As the city continued to prosper during the 18th century, Georgian Dublin became, for a short period, the second largest city of the British Empire and the fifth largest city in Europe, with the population exceeding 130,000. The vast majority of Dublin's most notable architecture dates from this period, such as the Four Courts and the Custom House. Temple Bar and Grafton Street are two of the few remaining areas that were not affected by the wave of Georgian reconstruction and maintained their medieval character.
Dublin grew even more dramatically during the 18th century, with the construction of many famous districts and buildings, such as Merrion Square, Parliament House and the Royal Exchange. The Wide Streets Commission was established in 1757 at the request of Dublin Corporation to govern architectural standards on the layout of streets, bridges and buildings. In 1759, the founding of the Guinness brewery resulted in a considerable economic gain for the city. For much of the time since its foundation, the brewery was Dublin's largest employer.
Late modern and contemporary
Dublin suffered a period of political and economic decline during the 19th century following the Act of Union of 1800, under which the seat of government was transferred to the Westminster Parliament in London. The city played no major role in the Industrial Revolution, but remained the centre of administration and a transport hub for most of the island. Ireland had no significant sources of coal, the fuel of the time, and Dublin was not a centre of ship manufacturing, the other main driver of industrial development in Britain and Ireland. Belfast developed faster than Dublin during this period on a mixture of international trade, factory-based linen cloth production and shipbuilding.
The Easter Rising of 1916, the Irish War of Independence, and the subsequent Irish Civil War resulted in a significant amount of physical destruction in central Dublin. The Government of the Irish Free State rebuilt the city centre and located the new parliament, the Oireachtas, in Leinster House. Since the beginning of Norman rule in the 12th century, the city has functioned as the capital in varying geopolitical entities: Lordship of Ireland (1171–1541), Kingdom of Ireland (1541–1800), island as part of the United Kingdom of Great Britain and Ireland (1801–1922), and the Irish Republic (1919–1922). Following the partition of Ireland in 1922, it became the capital of the Irish Free State (1922–1949) and now is the capital of the Republic of Ireland. One of the memorials to commemorate that time is the Garden of Remembrance.
Since 1997, the landscape of Dublin has changed immensely. The city was at the forefront of Ireland's rapid economic expansion during the Celtic Tiger period, with enormous private sector and state development of housing, transport and business.
