I posted that before I went to sleep, I've just woke up but you interested in the city which is good they need to be highlighted a lot more. Here's another fact about them I watched on a Oxford Uni lecture.

The conquest of Ireland

Cromwell cut off the king's head, in retaliation the catholic Irish under guidance of the Jesuits committed an attempted genocide of the Ulster protestants in 1641, tens of thousands were killed in a small population.

Cromwell was enraged about that and knew that Britain needed a reliable army so he created 'the new model army'. He needed funding for it so he negotiated with the city for his invasion and subjugation of Ireland.

They agreed but in return they wanted a third of Irish land, preferably the eastern and southern coastlines, so they can get a foothold, it's more densely populated and good port cities.

So Cromwell started his invasion in 1648 but soon ran out of money due to military setback and underestimate Irish resistance. So he had to return to the city a further two more times for funding, each time the city wanted another third of the island. So the city came to own all of the land.

There the city created the 'penal laws' against the Irish to make them third class citizens. One of the laws they passed was no Irish could come within 5 miles of a city or town that has a city of London business in it.

Cromwell died in 1658 and king Charles 2nd took over after Cromwell son failed to secure his rule. But to all the lord's of Ireland after still had to pay the city the taxes not to king Charles.

The monarchy kept their mouths shut and enforce the laws and held an army in Ireland for the city.

Irish still believed up to 1922 that it was the monarchy because the Norman's were the first to conquer Ireland. Though the real conquest and subjugation happened when Britain didn't even have a king.
