Oliver Cromwell (25 April 1599 – 3 September 1658) was an English military and political leader best known in England for his involvement in making England into a republican Commonwealth and for his later role as Lord Protector of England, Scotland and Ireland. Events that occurred during his reign and his politics are a cause of animosity between Ireland and the UK.
He was one of the commanders of the New Model Army which defeated the royalists in the English Civil War. After the execution of King Charles I in 1649, Cromwell dominated the short-lived Commonwealth of England, conquered Ireland and Scotland, and ruled as Lord Protector from 1653 until his death from a combination of malarial fever and septicaemia in 1658.**
