Editing Bolsover Castle (section)

===Medieval===
The original castle was built by the Peverel family in the 12th century and became Crown property in 1155 when [[William Peverel the Younger]] died. The [[Ferrers family]] who were [[Earls of Derby]] laid claim to the Peverel property.<ref name=bolsover>{{cite web|title=Bolsover|url=http://www.british-history.ac.uk/report.aspx?compid=50811#s8|work=A Topographical Dictionary of England (1848)|publisher=British History Online|access-date=11 September 2013}}</ref>

When a group of barons led by King [[Henry II of England|Henry II's]] sons&nbsp;– [[Henry the Young King]], [[Geoffrey II, Duke of Brittany|Geoffrey Duke of Brittany]], and Prince [[Richard I of England|Richard]], later Richard the Lionheart&nbsp;– [[Revolt of 1173–1174|revolted against the King's rule]], Henry spent £116 on building at the castles of Bolsover and [[Peveril Castle|Peveril]] in Derbyshire.<ref name=Eales23>{{harvnb|Eales|2006|p=23}}</ref><ref>{{harvnb|Colvin|Brown|1963|p=572}}</ref> The garrison was increased to a force led by 20&nbsp;[[knight]]s and was shared with the castles of Peveril and [[Nottingham Castle|Nottingham]] during the revolt.<ref name=Eales23/> King [[John, King of England|John]] ascended the throne in 1199 after his brother Richard's death. [[William de Ferrers, 4th Earl of Derby]] maintained the claim of the Earls of Derby to the Peveril estates. He paid John 2000&nbsp;[[Mark (money)#England and Scotland|marks]] for the lordship of the Peak, but the Crown retained possession of Bolsover and Peveril Castles. John finally gave them to Ferrers in 1216 to secure his support in the face of country-wide rebellion. However, the castellan [[Brian de Lisle]] refused to hand them over. Although Lisle and Ferrers were both John's supporters, John gave Ferrers permission to use force to take the castles. The situation was still chaotic when [[Henry III of England|Henry&nbsp;III]] became king after his father's death in 1216. Bolsover fell to Ferrers' forces in 1217 after a siege.<ref>{{harvnb|Eales|2006|p=24}}</ref>

The castle was returned to crown control in 1223, at which point £33 was spent on repairing the damage the Earl of Derby had caused when capturing the castle six years earlier. Over the next 20 years, four towers were added, the keep was repaired, various parts of the curtain wall were repaired, and a kitchen and barn were built, all at a cost of £181. From 1290 onward, the castle and its surrounding [[manorialism|manor]] were granted to a series of local farmers. Under their custodianship, the castle gradually fell into a state of disrepair.<ref>{{harvnb|Colvin|Brown|1963|p=573}}</ref>
