In 1751 Charles Calvert died, and Frederick, aged just 20, inherited from his father the title Baron Baltimore and the Proprietary Governorship of the Province of Maryland, becoming at once both a wealthy nobleman in England and a powerful figure in America.

[3] Calvert's inheritance coincided with a period of rising discontent in Maryland, amid growing demands by the legislative assembly for an end to his family's authoritarian rule.

Instead, he lived in England and on the European continent, particularly in Italy and, for a time in Constantinople, which he was eventually forced to leave after being accused of keeping a private harem.

[8] Such was Calvert's fascination with the Ottoman Turks that in 1766, on his return to England, he pulled down part of his London house, rebuilding it in the style of a Turkish harem.

According to Walpole, Calvert spent a great deal of money making the interior of the house "tawdry" and "ridiculous" in the "French" style.

[2] After deliberating for an hour and twenty minutes the jury acquitted Calvert,[2] believing that Woodcock did not make adequate attempts to escape.

[7] Sultana Watson offered many intimate details of life in the seraglio, including the predictable, unkind suggestion that Baltimore himself was barely able to satisfy one, let alone eight, mistresses.

[8] In this he seems to have been at least partly correct, as in July 1769 the British Ambassador to Russia reported that "Lord Baltimore arrived here last week from Sweden; I had the honour to present him to the Empress, who was pleased to receive his Ld extremely graciously.

With the aid of his physician, he conducted odd experiments on his houris: he fed the plump ones only acid foods and the thin ones milk and broth.

He arrived at Vienna with the train I have described; when the chief of police requested him to declare which of the eight ladies was his wife, he replied that he was an Englishman, and that when he was called upon to give an account of his sexual arrangements, if he could not settle the matter with his fists, it was his practice to set out instantly on his travels again.

[11]By this time it is evident that he was suffering from financial difficulties, and in 1768 he sold the family's great estate at Woodcote Park,[12] apparently to a wealthy Soho upholsterer.

His body was returned to London, lying in state at the Great Room of Exeter Exchange, Strand, and was interred in his family's vault at St. Martin's "with much funeral pomp, the cavalcade extending from the church to the eastern extremity of Epsom".

[1] According to Gentleman's Quarterly: "His Lordship had injured his character in his life by seduction, so that the populace paid no regard to his memory when dead, but plundered the room where his body lay the moment it was removed".

Henry Harford ultimately lost almost all his colonial possessions, though he remained wealthy due to his extensive inheritance in Great Britain.

One characterised him as "Feeble in body, conceited, frivolous, and dissipated, but withal generous and sympathetic ... [a man] who gave himself up to a life of pleasure".
