Vygovsky is based on an actual person, Ivan Vyhovsky, who succeeded Bohdan Kymelnytsky as hetman of the Ukrainian Cossacks. Vyhovsky ruled from 1657-1659. He went to war against the Muscovite Tsardom, which he successfully conducted, but the opposition forced him to resign Hetman. He was succeeded by the son of Bohdan Khmelnitsky, Yurii.
