Published in 1755, the same year that a French and Indian force defeated a British army under Gen. Edward Braddock near Fort Duquesne, Thomas Jefferys’s map attempted to justify English claims in North America. Jefferys based his on the work of a French cartographer but transformed it into British propaganda, identifying French settlements as “incroachments” on English territory. The map later became a part of William Douglass's widely read Summary, Historical and Political ...of the British Settlements in North-America (1755). Encyclopedic in its coverage, the Summary remains an important source of information concerning British North America.
