Claim: Henry Muddiman began producing two regular newsbooks in late 1659 at the suggestion of George Monck (who was the 1st Duke of Albemarle, KG), which eventually resulted in Muddiman having a monopoly in the printing business.
Evidence: He began producing two regular newsbooks - Parliamentary Intelligencer and Mercurius Publicus - in late 1659 on the proceedings of the newly reconvened Rump Parliament. This seems to have been at the suggestion of George Monck, who also received good publicity. George Monck, 1st Duke of Albemarle, KG (6 December 1608 – 3 January 1670) was an English soldier and politician, and a key figure on both sides of the English Civil War, as well as the Restoration of the monarchy to King Charles II in 1660. On 16 April 1660 this role was secured when all other such journals were banned particularly those of Marchamont Needham the chief Cromwellian publisher. Muddiman received a monopoly of print along with arch-royalist John Birkenhead as a supervising editor.
