In the beginning of the 13th century, Lithuanians repeatedly attempted to annex the principality, and in 1225/26 even Davyd, the prince of Toropets, was killed in battle.

In 1253, Toropets already belonged to the duchy of Lithuania and was used as a base for attacks on adjacent lands.

After the 1250s, Toropets was not mentioned in the chronicles, though the geography of Lithuanian attacks shows that in 1285 it still belonged to Lithuania.

[2] Chronicles mention that Toropets was finally annexed by the Grand Duchy of Lithuania in 1355, though Valentin Yanin argued it happened in the 1250s.

[2] For most of the princes of Toropets, we do not know the extent of their rule; they are typically mentioned in connection to one or several isolated events.
