|Present holder||Prince Harry|
|Remainder to||the 1st Duke's heirs male of the body lawfully begotten|
|Subsidiary titles||Earl of Dumbarton|
The dukedom was first conferred on 24 November 1801 upon Prince Augustus Frederick, the sixth son of King George III. He was made Baron Arklow and Earl of Inverness at the same time, also in the Peerage of the United Kingdom. The title became extinct upon Prince Augustus Frederick's death in 1843. Although he was survived by a son and daughter by Lady Augusta Murray, their marriage had been annulled for lack of royal permission under the Royal Marriages Act 1772, rendering the children illegitimate under English law and unable to inherit titles from their father. Both children by the annulled marriage died childless, rendering the issue of their inheritance moot.
In 2018, the title was recreated and granted to Prince Harry to mark the occasion of his wedding to Meghan Markle. Prince Harry was granted the subsidiary titles Earl of Dumbarton in Scotland and Baron Kilkeel in Northern Ireland at the same time.
A title associated with Sussex first appeared with the Kingdom of Sussex, an Anglo-Saxon kingdom that was annexed by the Kingdom of Wessex about 827 and that later became part of the Kingdom of England. In charters, Sussex's monarchs were sometimes referred to as ealdormen, or duces in Latin, which is sometimes translated as "dukes".
The title of Duke of Sussex was conferred upon Prince Augustus Frederick, the sixth son of King George III, on 24 November 1801. Prince Augustus Frederick purportedly married first Lady Augusta Murray at St George's Hanover Square Church, Westminster in 1793, and second Lady Cecilia Gore at Great Cumberland Place, London, on 2 May 1831. Both "marriages" were in contravention of the Royal Marriages Act 1772; thus the couple's children were illegitimate. Not being the Prince's legitimate wife, Lady Cecilia could not be received at court. On 30 March 1840, she was given the title of Duchess of Inverness in her own right by Queen Victoria. Since Augustus Frederick had no legitimate issue, his titles became extinct on his death in 1843.
In 1999, before the wedding of Prince Edward, the youngest son of Elizabeth II, some had suggested the Dukedoms of Sussex or Cambridge as the most likely titles to be granted to him. Instead, Prince Edward was created Earl of Wessex, and it was announced that he would eventually be created Duke of Edinburgh, a title currently held by his father, Prince Philip. There was again speculation that Prince William might be given the Sussex title on his wedding to Catherine Middleton in April 2011, but he was instead created Duke of Cambridge.
On 19 May 2018 Prince Harry was created Duke of Sussex in England, Earl of Dumbarton in Scotland, and Baron Kilkeel in Northern Ireland to mark the occasion of his wedding to Meghan Markle, who thereby became the first Duchess of Sussex.
