There are certain names in Ireland that you can't utter without being greeted with a look of disdain and/or disgust by those around you thanks to their rather infamous relationships with our country and its bloody history.

Here is IrishCentral's list of the top most-disliked people in Ireland. 

Diarmuid Mac Murrough

He invited the English to Ireland in 1169 after losing his throne as King of Leinster. King Henry II took him up on it and the Irish have been trying to get rid of the British ever since.

Oliver Cromwell

Cromwell decided to use Ireland as his own killing field to advance his political career in Britain. Murdered and deported tens of thousands of Irish as slaves.

Charles Trevelyan

Britain’s overseer of Ireland during the Great Hunger. He decided that economic policy and ‘not coddling the poor’ was more important than millions starving.

Lord Lucan

The worst landlord in Ireland during the Great Hunger. He turned 10,000 people out of their homes in Ballinrobe in Mayo alone. Thousands starved to death as he ruthlessly cleared the land.

Captain William O’Shea

He decided to divorce Kitty O’Shea despite knowing it would bring down Charles Stewart Parnell, who was on the verge of achieving Home Rule. He was egged on by British interests to do so. Despite the fact that O’Shea and Kitty were separated when she met Parnell, the resulting Victorian-era scandal took down Ireland’s "Uncrowned King."

David Lloyd George

Also known as ‘the Welsh Wizard,’ this British Prime Minister split the Irish delegation during the treaty talks and insisted on Irish partition and keeping his unionist backers happy at all costs.

He was a Parachute Regiment commander in Derry in 1972 when he unleashed the paras to fire on unarmed civilians on Bloody Sunday. 26 people were shot and 14 died. Wilford subsequently became known as “the Butcher of the Bogside.”
