Initially Lyubutsk was part of the Principality of Bryansk. In the 14th century, the city was acquired by the Grand Duchy of Lithuania. The town was mentioned in 1372 when Algirdas of Lithuania and Mikhail II of Tver marched against Dmitry Donskoy, Grand Duke of Moscow, who managed to stop the joint army. After a period of stand off, Algirdas and Dmitry reached an agreement and concluded the Treaty of Lyubutsk.
