The Anglo-Saxon Chronicle records that in 915 AD, Edward the Elder ordered the construction of two burhs (earthwork fortifications) either side of the River Great Ouse at Buckingham as part of his campaign against the Danes.

It was held by various families until it escheated to the Crown on the attainder of Edward Stafford, 3rd Duke of Buckingham in 1521.

In 1526 a further royal grant was made to William Carey, whose son sold the borough to Robert Brocas in 1552.

The bailiff was to hold the offices of escheator, coroner and clerk of the market and to act as a justice of the peace within the borough.

[2] In 1684 the borough received a new charter from Charles II, by which the bailiff and principal burgesses were given the new titles of "Mayor and Aldermen".

In 1688 James restored the charter of Mary I and the older titles of "Bailiff and Principal Burgess" were resumed by the mayor and aldermen.

In the 18th century the earliest known references to the offices of recorder and town clerk, not mentioned in the charter, appear.

The parliamentary constituency enlarged at the same time to take in a number of surrounding villages as well as the borough itself.

[11] Castle House was used as an area office by Aylesbury Vale District Council until the late 1970s, but was then converted back to residential use.
