LUTSK (Polish, Luck), a town of southern Russia, in the government of Volhynia, on the Styr, 51 m.
Lutsk is the seat of a Roman Catholic bishop.
From the 9th century the towns of Volhynia-Vladimir, Ovruch, Lutsk and Dubno were ruled by descendants of the Scandinavian or Varangian chief Rurik, and the land of Volhynia remained independent until the 14th century, when it fell under Lithuania.
Brest-Litovsk, at the western issue from the marshes of the Pripet, the towns of Dubno, Lutsk and Bobruisk constitute the second line of defence.
In 1429, instigated by the emperor Sigismund, whom he magnificently entertained at his court at Lutsk, Witowt revived his claim to a kingly crown, and Jagiello reluctantly consented to his cousin's coronation; but before it could be accomplished Witowt died at Troki, on the 27th of October 1430.
