The 1st Duke of Buckingham and Normanby built Buckingham House in the early 1700s, which eventually came into the hands of the monarch and is now Buckingham Palace. The last holder of the dukedom, the 3rd Duke of Buckingham and Chandos, died in 1889.

There have also been Earls of Buckingham and Marquesses of Buckingham.
