The result of over fifty years’ archival research, the book demonstrates the fundamental importance of the Huguenot refugees to the 1688 Glorious Revolution, victory in Ireland, the foundation of the Bank of England, and the subsequent defeat of Louis XIV and the rise of British power in the eighteenth century.

The Glorious Revolution of 1688-9 was a decisive moment in England's history; an invading Dutch army forced James II to flee to France, and his son-in-law and daughter, William and Mary, were crowned as joint sovereigns. The wider consequences were no less startling: bloody war in Ireland, Union with Scotland, Jacobite intrigue, deep involvement in two major European wars, Britain's emergence as a great power, a 'financial revolution', greater religious toleration, a riven Church, and a startling growth of parliamentary government. Such changes were only part of the transformation of English society at the time. An enriching torrent of new ideas from the likes of Newton, Defoe, and Addison, spread through newspapers, periodicals, and coffee-houses, provided new views and values that some embraced and others loathed. England's horizons were also growing, especially in the Caribbean and American colonies. For many, however, the benefits were uncertain: the slave trade flourished, inequality widened, and the poor and 'disorderly' were increasingly subject to strictures and statutes. If it was an age of prospects it was also one of anxieties.

Emanuel Swedenborg (1688-1772) won fame and infamy as a natural scientist and visionary theosopher, but he was also a master intelligencer, who served as a secret agent for the French king, Louis XV, and the pro-French, pro-Jacobite party of "Hats" in Sweden. This study draws upon unpublished diplomatic and Masonic archives to place his financial and political actitivities within their national and international contexts. It also reveals the clandestine military and Masonic links between the Swedish Hats and Charles Edward Stuart ("Bonnie Prince Charlie"), providing new evidence for the prince's role as hidden Grand Master of the Order of the Temple. Swedenborg's usage of Kabbalistic meditative and interpretative techniques and his association with Hermetic and Rosicrucian adepts reveal the extensive esoteric networks that underlay the exoteric politics of the supposedly "enlightened" eighteenth century, especially in the troubled "Northern World" of Sweden and Scotland.
