Diarmuid MacMurrough, King of Leinster kidnapped the King of Breifne’s wife. Then Rory O’Connor, the High King of Ireland fired him from being the King of Leinster. Diarmuid still wanted to be king so he hired some Normans, lead by Strongbow to help him get the throne back. Diarmuid had to pay Strongbow so he said that he could marry his daughter and become king when Diarmuid died. Strongbow agreed to this. They first came to Ireland at Bannow Bay, Wexford in 1169 and soon they got the throne back for Diarmuid. King Henry II, King of England and part of France, thought that Strongbow was getting too powerful since Strongbow wasn’t actually the king, so Henry decided to take over the whole of Ireland. He sent over some other Normans who arrived at Ireland in Baginbun, Wexford in 1170. Then King Henry II became King of Ireland as well.
