Angevin Empire was created in 1154.

An Angevin is a native or resident of Anjou.

It was because of him and his constant abusing of powers for financial reasons why the barons of England made the Magna Carta. So he made a huge political impact in this way. He lost part of the Angevin empire: Normandy.

King John was in some ways a bad king. He was good on administrative terms but personal faults held him back. i.e. John was a talented soldier but his personal opinion got the better of him in battles so although he won many battles and an empire, he also lost lots of land, money and alot of the Plantagenet( or Angevin) empire.
