A senior descendant of Vsevolod the Big Nest and also of Yaroslav II of Vladimir (Dmitry was great-grandson of Yaroslav II's third son Andrey II of Vladimir), he inherited Suzdal in 1359 and Nizhny Novgorod in 1365. His policy towards Tatars was conciliatory for the most part, as his eastern lands were continuously exposed to their attacks. After some rivalry with Dmitry of Moscow, he was installed by the Khan of the Golden Horde as the Grand Duke of Vladimir in 1360. During his reign, he repeatedly quarreled with the Novgorod Republic over the raids of Novgorodian pirates who looted his own capital and Tatar markets along the Volga River.
Three years later he was dethroned and had to make peace with Dmitry by marrying him to his daughter, Eudoxia. Joining his army with Dmitry's, he led an allied assault on Volga Bulgars and Mordovia. In 1377, the allied armies were defeated by the Tatars at the Battle on Pyana River, because (as the chronicler put it) they were too drunk to fight. However, in 1382, Dmitry Konstantinovich took the side of Khan Tokhtamysh in taking over Moscow and sent his sons to serve in the Tatar army.
