Henry and his wife had eight kids and john was the smallest of them all. John's father, Henry passed away and his oldest son had to become king but, three of his older brothers also died. So john took the throne.
John was king and started to go into battle with other countries , like france and lost many battles. Since the king lost so many he needed a way to bring more money to him.
King John started to have problems with the baran's because they didnt agree that paying taxes were a good thing and started to say "no taxations without representation".
Many of his baran's thought he was the worst king because he sent his former wife to jail , killed his nephew , and raised the taxes everytime he lost a battle to france.
The baran's decided to make the Magna Carta which King John was forced to sign it. The magna carta stated that your entitled to a jury from your peers to prove that your guilty. The magna carta was a sign of liberty and was the base of the declaration of independence.
King John ended up passing away. Henry the 3rd took his place and ruled England after him and the magna carta lasted until the 1300s.
