Names
Latin Gerzika, terra Lettia; the Russian Lotygola. A Latgalian principality on the Daugava in what is now Latvia, a vassal of Polotsk. Its ruler, King Visvaldis (Vissewalde, rex de Gerzika), called rex in the Livonian Chronicle of Henry, allied with Lithuanians against the crusaders and was defeated in 1209 by Bishop Albert of Riga, forced to receive his own land back as a fief of the Bishopric. The principality was extinguished by the crusaders by 1239.
