"EUROPÄISCHE MÜNZEN UND MEDAILLEN · POLEN, KÖNIGREICH Stanislaus August, 1764-1795. Dukat 1786 E-B, Warschau. GOLD. RR Leicht gewellt, sehr schön +. (kingdom of Poland, Stanislaus Augustus, 1764-95, ducat of 1786, Warsaw mint. Very rare, lightly bent, very fine or better.)"

The kingdom of Poland, weakened by the devastation of the Great Northern War (1700-21), fell under the domination of her neighbors, Prussia, Russia and Austria. Stanislaus Poniatowski, a former lover of Catherine the Great, was installed as her puppet king on the death of the Saxon August III. When he proved to be insufficiently pliant, the partitions began. In three slices, in 1772, 1793 and 1795, the entire state was devoured. Even then, Stanislaus could not rally the greedy and selfish Polish nobility to defend the country. This type was struck in small numbers 1784-86.
