The United Kingdom was created over several centuries, as the English conquered Wales, Scotland and Ireland.
I believe that England and Switzerland were the only European countries not conquered in WW2 and if not Switzerland than Ireland
As far as I know Ireland was never conquered by Rome. Any sources?
Oliver Cromwell, who was a kind of dictator after the Parliament rebellion, the civil war and killing Charles I Stuart. He was also the one who conquered Ireland.
Ireland had been conquered by England in a series of wars from 1536-1607. It freed itself from English rule in 1921, following the Irish War of Independence, and became the Irish Free State. In 1937, Ireland left the British Commonwealth and became the Republic of Ireland.
The armies of Elizabeth completed the conquest of Ireland in the "9 Years War" of 1594-1603 when the last independent areas were finally conquered.
generally speaking the Romans considered Ireland to be too great a risk for too little a reward to conquer, however there is evidence that the Romans established atleast one trading site in Ireland
