1761 The Natural and Civil History of the French Dominions in North and South America

compiled and engraved by prominent English geographer Thomas Jefferys, stands as a landmark piece of wartime cartography and imperial propaganda. Published in London amid the geopolitical fires of the Seven Years' War (1756–1763), this monumental folio served a dual purpose for the British public and state. On one hand, it provided an unparalleled, highly detailed geographic and ethnographic survey of New France, Louisiana, and the French Caribbean. On the other, it acted as a strategic inventory of Britain’s enemy at the absolute zenith of their global conflict. The work is particularly famous for its eighteen exquisitely detailed folding maps and town plans, including crucial layouts of Quebec, Montreal, and New Orleans. By masterfully synthesizing and translating clandestine French engineering surveys and Jesuit accounts, Jefferys gave the British political elite a literal and figurative roadmap of the very territories British forces were actively conquering.

The historical significance of this work peaked with its 1761 issue, which reflects the rapidly shifting tides of colonial empire. As British forces successfully captured key French strongholds, Jefferys hastily updated his text, inserting "star pages" (numbered 129*-138*) to capture the immediate aftermath of the Siege of Quebec and General Wolfe’s victory on the Plains of Abraham. This makes the book a living document of the collapse of New France and the birth of British dominance in North America. By meticulously documenting the trade, native alliances, and topography of the French Americas just as they were changing hands, Jefferys' work captured the exact moment the global balance of power shifted. Today, it remains an indispensable primary source for historians studying 18th-century colonialism, Indigenous history, and the cartographic warfare that shaped the modern map of the Western Hemisphere.
