King John had been married to Isabella of Gloucester for several years but they had no children. When John became king he quickly obtained a divorce leaving himself free to arrange a marriage that would give him political gain. Within the year he would marry Isabella of Angouleme, the daughter of an important baron in Aquitaine. ^[1]

Eager to make peace with the count of Angouleme, John marries his only daughter, Isabella. Isabella was engaged to Hugh of Lusignan, a family which John was worried about due to their power and influence and the fact that an alliance between Angouleme and Lusignan would be a danger to him. Isabella was around fifteen years old. ^[2]

John and Isabella returned to England in late September and were both crowned at Westminster Abbey.

In France the Lusignans were causing problems still angry over John's marriage to Isabella. John ordered that an army should assemble at Portsmouth. Instead of taking the assembled army John used the money to hire mercenaries and took them instead.

Arthur of Brittany and the Lusignans had laid siege to Mirabeau Castle trapping Eleanor of Aquitaine inside. King John launched a rescue mission to free her. Arthur was captured by William de Braose and was handed over to King John. Many other important knights were also captured and it was an important and famous victory for the English king. Those that were captured were treated badly by King John. He could have ransomed them for their freedom and made a lot of money, instead he kept them prisoner locked in dungeons. Some he had shipped to England and imprisoned. Arthur was sent to the dungeon in the castle at Falaise in Normandy.

Henry, the future king of England, was born at Winchester Castle.

King John's eldest son Henry was crowned King Henry III at the abbey church of Gloucester by Peter des Roches the Bishop of Winchester. The Earl of Pembroke, Earl Marshal of England (William Marshal), was declared Regent.
