Ипатьевская летопись
Krasny (originally Krasn or Krasen) is first mentioned in 1165 by the Hypatian Codex, when Davyd Rostislavich, Prince of Smolensk, gave Krasen to his nephew, Roman of Vitebsk. Between second half of the 14th century and the middle of the 17th century, the area belonged intermittently to the Grand Duchy of Lithuania, to Poland, and to the Grand Duchy of Moscow. Since 1654, it was finally transferred to the Tsardom of Russia.
