Russia was in an expansioinst mode.
The Tatars hadn't quite figured out that agriculture thing made regular marauding raids deep into Ukraine and even Polish territories. They brought the grain, goods, young women and some boys back to Crimea. They exported slaves to Turkey. The Cossacks were established on the Dnieper River near the current city of Zaporizhia (and various other spellings) to keep them at bay.
Kathrine II tried to push back the Ottoman empire all around the Black Sea, out of the Balkans, and even hoped to return Constantinople to Christian control. That didn't quite happen, but Crimea was invaded and captured in 1768.

ÂThere is a cult of ignorance in the United States, and there has always been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge.Â
