A finely detailed first edition 1794 map of Silesia by Robert Wilkinson, in what was then part of the Holy Roman empire. The map details the principalities within this duchy, which was bordered by Poland, Hungary, Moravia, Bohemia and Lusatia. Silesia passed from Habsburg to Prussian control in 1740. In 1806 Napoleon's French forces invaded, dissolving the Holy Roman empire and ultimately inspiring the events leading to the unification of Germany in 1871. After two world wars, Silesia has today splintered into German, Austrian, Czech and Polish Silesias. engraved by Thomas Conder for the 1794 first edition of Robert Wilkinson's General Atlas.
