Central and Eastern Europe in 1740 (french)
The title is ‘Central and Eastern Europe, 1740’
The key is: 'Possessions of the Austrian Habsburgs
Kingdom of Prussia
Borders of the Holy Roman Empire
Border between Russia and the Ottoman Empire
And the rest should be fairly obvious; 'Souabe’ is Swabia, 'Saxe’ is Saxony, 'Varsovie’ is Warsaw, etc.
