In 1941, during the World War II, the German Nazi General Paul Ludwig Ewald von Kleist created a heavily fortified defensive line known as the Mius-Front along the Mius river. It was an arena of fierce battles during the Rostov Defensive Operation in the 1941−1943 Battle of Rostov campaigns. During the 1943 Donbas Strategic Offensive Soviet troops finally broke through the Mius-Front near the village of Kuybyshevo.
