Duke of Sussex

First created in 1801, the title lapsed in 1843 but was revived when Queen Elizabeth II bestowed it on her grandson Prince Harry on 19 May 2018 just before his marriage to Meghan Markle, who then became the Duchess of Sussex.

The title of Duke of Sussex was first conferred on 24 November 1801 upon Prince Augustus Frederick,[4] the sixth son of King George III.

Although the Prince was survived by a son and daughter by Lady Augusta Murray, their marriage (purportedly solemnized at St George's Hanover Square Church, Westminster, in 1793) 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.

On 2 May 1831, the Prince married a second time (and again in contravention of the Royal Marriages Act 1772) to Lady Cecilia Gore at Great Cumberland Place, London.

[1][6] On his wedding day, it was announced that he would become Duke of Sussex in England, with the subsidiary titles of Earl of Dumbarton in Scotland and Baron Kilkeel in Northern Ireland.
