In its heyday in the 18th century, Cherkassk was a busy city with a strong fortress. The city was the major residence of quite a few famous Don cossacks of the 17th and 18th centuries, including Stepan Razin, Yermak Timofeyevich, Kondraty Bulavin and Matvei Platov. It was also the location of fierce battles between Russian, Ottoman, Crimean and Cossack forces.
