Field Marshal Pyotr Rumyantsev was not only one of the greatest commanders in history, who defeated Frederick of Prussia, was rightfully considered the teacher of Alexander Suvorov and a reformer of the Russian army, but also an outstanding manager. He became the first ruler of Little Russia after the “hetmanate” and over several decades turned a poor region into a prosperous one, and from the Ukrainian elite he promoted talented diplomats, politicians, and generals who served the Russian Empire. He stopped the feuds between Little Russians and Great Russians. And besides, he defeated the Turks, Swedes, Prussians and broke women's hearts. It was not for nothing that his contemporaries considered him the wisest man in Russia. It's time to tell the whole truth about him.
