Dublin History

The earliest reference to a settlement in the Dublin area was in the writings of Ptolemy in 140 AD, referencing the settlement as Eblana Civitas. In the 9th century, Dublin was established as a Viking settlement and remained under Viking control until the Norman invasion of Ireland from Wales in 1169. The King of Leinster enlisted help from Strongbow to conquer Dublin. Strongbow then declared himself king after gaining control. It was around this time that the barony of Dublin City was separated from the barony of Dublin. The two were redesignated as the City of Dublin in 2001.

The Tudor conquest of the country in the 1500s created a new era for the city, which once more became the center of rule in Ireland. Queen Elizabeth I of England, in an attempt to make Dublin Protestant, established Trinity College in 1592 and ordered that the Catholic cathedrals be converted to Protestant. Dublin had a population of 21,000 by 1640 before a plague killed nearly 50% of the population. The city once more prospered, reaching more than 50,000 people by 1700.

By the 18th century, Dublin boasted a population of more than 130,000 and was, briefly, the second-largest city in the British Empire and the fifth largest in Europe. It grew quickly during the 18th century, when many of its most well-known buildings were constructed.

By 2020, the Central Statistics Office predicts the Dublin Region will reach a population of 2.1 million by 2020, with Dublin City will have a population of 610,000. By 2031, the Dublin population could surpass 5 million, with most people living in the greater Dublin area of Dublin, Kildare, Meath and Wicklow rather than the other regions.
