==Life== In 1356, Algird took the region of Bryansk, which included Trubetsk and Starodub, from the Principality of Smolensk and granted it to his son Dmitry to govern.<ref name=dm>{{cite encyclopedia | last=Jonynas | first=Ignas |authorlink=Ignas Jonynas | editor-first=Vaclovas |editor-last=Biržiška | encyclopedia=Lietuviškoji enciklopedija | title=Dimitras | year=1933–1944 | publisher=Spaudos Fondas | volume=VI | location=Kaunas | pages=912–914|language=lt}}</ref> The territory was in the far northeast from the heartlands of the Grand Duchy of Lithuania and bordered the Principality of Moscow. In 1370, Dmitry Donskoy, the grand prince of Moscow, unsuccessfully attempted to conquer the territory. In 1372, Dmitry witnessed the Treaty of Lyubutsk between Algird and Dmitry Donskoi.<ref name=matu/>

After his father's death in 1377, Dmitry supported his elder brother Andrei of Polotsk against their younger half-brother Jogaila, who became the grand duke of Lithuania. Andrei, believing that he was the rightful heir to the throne, organized a coalition against Jogaila, which included Polotsk, Pskov, the Livonian Order, and Moscow.<ref>{{cite encyclopedia | last=Jonynas | first=Ignas |authorlink=Ignas Jonynas | editor=Vaclovas Biržiška | encyclopedia=Lietuviškoji enciklopedija | title=Andrius | year=1933–1944 | publisher=Spaudos Fondas | volume=I | location=Kaunas | pages=575–585|language=lt}}</ref> Dmitry took a more passive role in the coalition: he did not wage a direct war against Lithuania and did not defend his domain when it was attacked by Moscow's army in 1379.<ref name=dm/> Dmitry and his family followed the retreating Russian army into Moscow where Dmitry Donskoi granted him Pereslavl-Zalessky. In 1380, Dmitry led a Russian banner in the Battle of Kulikovo against the Golden Horde. Russian chronicles praise his and his brother's tactical skills.<ref name=dm/>

After 1380, Dmitry is mentioned in written sources only twice.<ref name=dm/> After his brother Andrei was captured by Skirgaila's forces and imprisoned in Poland, Dmitry reconciled with Jogaila, now King of Poland, in 1388. He returned to his former domain in Bryansk. Dmitry died in 1399 in the Battle of the Vorskla River against the Golden Horde.<ref name=matu/>

Dmitry's son Michał Trubetsky is considered to be the ancestor of the Trubetskoy family.<ref name=matu/>
