Who dated George IV of the United Kingdom?

George IV (George Augustus Frederick; 12 August 1762 – 26 June 1830) was King of the United Kingdom of Great Britain and Ireland and King of Hanover from 29 January 1820 until his death in 1830. At the time of his accession to the throne, he was acting as prince regent for his father, King George III, having done so since 5 February 1811 during his father's final mental illness.

George IV was the eldest child of King George III and Queen Charlotte. He led an extravagant lifestyle that contributed to the fashions of the Regency era. He was a patron of new forms of leisure, style and taste. He commissioned John Nash to build the Royal Pavilion in Brighton and remodel Buckingham Palace, and commissioned Jeffry Wyatville to rebuild Windsor Castle. George's charm and culture earned him the title "the first gentleman of England", but his dissolute way of life and poor relationships with his parents and his wife, Caroline of Brunswick, earned him the contempt of the people and dimmed the prestige of the monarchy. He excluded Caroline from his coronation and asked the government to introduce the unpopular Pains and Penalties Bill in an unsuccessful attempt to divorce her.

George's rule was tarnished by scandal and financial extravagance. His ministers found his behaviour selfish, unreliable and irresponsible, and he was strongly influenced by favourites. During most of George's regency and reign, Lord Liverpool controlled the government as prime minister of the United Kingdom. Liverpool's government presided over Britain's ultimate victory over Napoleon and negotiated a peace settlement with the French. After Liverpool's retirement, George was forced to accept Catholic emancipation despite opposing it. His only legitimate child, Princess Charlotte, predeceased him in 1817, as did his childless younger brother Prince Frederick in 1827, so he was succeeded by another younger brother, William IV.

Grace Dalrymple Elliott (c. 1754 – 16 May 1823) was a Scottish courtesan, writer and spy resident in Paris during the French Revolution. She was an eyewitness to events detailed in her memoirs, Journal of my life during the French Revolution (Ma Vie sous la Révolution) published posthumously in 1859. She was mistress, first to the future George IV, by whom she is said to have borne an illegitimate daughter, and then to the Duke of Orléans. Elliott trafficked correspondence and helped condemned Royalists and members of the French nobility escape from the First French Republic during the Reign of Terror. She was arrested several times but managed to avoid the guillotine, and was released following the military coup that ended the Terror and resulted in the execution of Robespierre.

In the acclaimed but widely controversial 2001 film adaptation of her memoirs by French New Wave director Éric Rohmer as The Lady and the Duke, Grace Elliot was played by English actress Lucy Russell.

Elizabeth Conyngham, Marchioness Conyngham (née Denison; 29 March 1770 – 11 October 1861) was an English courtier and noblewoman. She is thought to be the last mistress of George IV of the United Kingdom.

Olga Alexandrovna Zherebtsova (née Zubova; Russian: Ольга Александровна Жеребцова; 1766–1849), also known as Madame Gerebtzoff, was a Russian aristocrat and socialite, known foremost for her political involvement and love life. She was the sister of the celebrated Zubov brothers, Prince Platon and Counts Nikolay and Valerian.

After her brothers' fall from grace following Catherine II's death, they conspired with Count Pahlen to assassinate her successor Paul whom they viewed as the author of their misfortunes. The conspirators met and discussed their plans at Zherebtsova's house. Some maintain that she appropriated the funds the British government passed through her lover Charles Whitworth, 1st Earl Whitworth to the conspirators. "Once diplomatic relations with England were broken, Whitworth was ordered to leave the capital with all his staff".

Zherebtsova followed Lord Whitworth to England where she was shocked to learn about his prospective betrothal to the widow of John Sackville, 3rd Duke of Dorset. It was rumored that Madame Gerebtzoff extorted from her rival some 10,000 pounds before turning her attention to the Prince Regent, whose mistress she is said to have become. She is even said to have given birth to a natural son, named George Nord, after his purported royal father.

In the declining years of her life, Madame Gerebtzoff returned to the Russian capital, where she again became immersed in court intrigues through her powerful son-in-law, Prince Aleksey Orlov. In the 1840s, she was the patron of Alexander Herzen, who would recall her character and opinions with admiration in his memoirs "My Past and Thoughts":

Like a tree in winter, she maintained the linear outline of her boughs after the leaves had fallen off and the scraggy bare branches had been pinched with cold, all the more clearly demonstrating her magnificent stature, her daring bulk, and the trunk, though white with frost, still stalking lordly and sulkily and braving every tempest and gust.

Mary Robinson (née Darby; 27 November 1757 – 26 December 1800) was an English actress, poet, dramatist, novelist and celebrity figure. She lived in England, in the cities of Bristol and London; she also lived in France and Germany for a time. She enjoyed poetry from the age of seven and started working, first as a teacher and then as an actress, from the age of 14. She wrote many plays, poems and novels. She was a celebrity, gossiped about in newspapers, famous for her acting and writing. During her lifetime she was known as "the English Sappho". She earned her nickname "Perdita" for her role as Perdita (heroine of Shakespeare's The Winter's Tale) in 1779, and was the first public mistress of King George IV while he was still Prince of Wales.
