Pontefract Castle is located in Yorkshire to the east of Leeds. It is most famous for being the place that Richard II, the King of England, was murdered in 1400. The castle was destroyed at the end of the English Civil wars although some remains can still be visited.
The marriage of Thomas, Earl of Lancaster to Alice de Lacy, the heiress of the of the powerful Henry de Lacy, gave the Earl even more titles and properties. One of these properties was Pontefract Castle in Yorkshire.
Lancester held the first of two meetings to gather support of Barons and the clergy to remove the Despensers from power. The second meeting at Sherborn-in-Elmet near York was held on June 28th.1
Edward advanced up the Severn Valley and crossed the river at Shrewsbury. Several of the Marcher Lords surrendered to the King without a fight. Lancaster had moved to his base at Pontefract. The King took time to take control the castles belonging to the Marcher Lords.1
Lancaster left his base at Pontract and headed north. At the bridge crossing the river Ure at Boroughbridge he was halted by an army led by Andrew Harcley, the Earl of Carlisle. Harcley held the bridge against Lancaster's attacks and Lancaster was forced to surrender. Lancaster was taken back to Pontefract Castle where Edward had taken control.
Richard II died some time between the 9th and 17th of February 1400 while being imprisoned at Pontefract Castle. The cause of his death is not known. He died at the age of 33.3
Following the earlier Lincoln rebellion, a larger rebellion began further north in Yorkshire. This rebellion again protested against Henry VIII's unpopular policies and advisers. They wanted Henry to put a stop to the dissolution of the monasteries and they wanted the removal of the Archbishop of Canterbury, Thomas Cranmer and Henry's adviser Thomas Cromwell. The leader of the rebellion was Robert Aske, a lawyer and excellent organiser. Somewhere between 30,000 and 35,000 rebels were involved and they took control of Pontefract Castle which fell to them without any resistance.
