Teodor Narbutt is best remembered as the author of a nine-volume Polish-language history of Lithuania from the early Middle Ages to the Union of Lublin.
Teodor Narbutt was born in 1784 in the village of Szawry (present-day Voranava District of Belarus) in the Polish–Lithuanian Commonwealth, to a notable szlachta family of Trąby coat of arms. Early in his youth his fatherland was partitioned between Russia, Austria and Prussia. After graduating from a Piarist college at Lyubeshiv, Narbutt entered the Vilna Academy, where in 1803 he graduated in engineering. He then moved to Saint Petersburg, where he joined the Cadet Corps. He served in the Imperial Russian Army, where he became a captain in the field engineering corps. He took part in the 1807 and 1812 Russian campaigns against Napoleon Bonaparte. In 1809 he constructed the Bobruysk fortress (modern Babruysk, Belarus), for which he was awarded the Order of Saint Anna. [1]
Narbutt had no education in history and is infamous for his uncritical, amateurish approach to historical sources. In the absence of written sources, he often used dubious sources and his own imagination. Some historians believe him to be of good intentions if naive, [2] while others accuse him of actively creating forgeries. [1]
