Why I would think that backroom politics happened during the Tudor and Stuart Early Modern period beats me. The UK National Archives has made available online documents exposing backroom politics from 1509-1714 for academic research as follows:
“The largest set of government documents from the Early Modern period is now available online for academic research. The fourth and final part of State Papers Online, 1509-1714 offers students and researchers unprecedented access to documents covering the full range of the Tudor and Stuart governments’ domestic and foreign activities.
Letters and top secret reports expose the backroom politics of the Tudor and Stuart regimes, alert to the threats of internal rebellion and foreign invasion. The material includes accounts of espionage and treason, detailed ambassadorial intelligence reports, and letters between the monarchs and rulers of Europe as they vied for power and brokered alliances.
Caroline Kimbell, Head of Licensing at The National Archives, said: ‘The completion of the State Papers Online project is not only transforming our research experience and usability of challenging records collections, but it’s also extending their access to new audiences, whilst revealing previously unknown material. It’s fantastic that the collection has been taken up worldwide and we eagerly await more revelations from the foreign relations records, which have been far less thoroughly explored than the domestic records.’
Published in four parts over four years, State Papers Online, 1509-1714 is the largest digital manuscript archive of its kind to link original historical manuscripts to their fully text-searchable Calendars. Now with the completion of the series, users can cross-search almost three million documents housed in separate collections from The National Archives and the British Library.
The online archive, which was digitised by Gale, part of Cengage Learning, in collaboration with The National Archives, is available to view online at The National Archives, as well as public libraries, academic institutions, museums and galleries.”
