Volquin

Volkwin (also Wolquin, Folkwin, Folkvin, Wolguinus, Wolgulin, Middle High German: Volkewîn; died 22 September 1236) was the Master (Herrmeister) of the Livonian Brothers of the Sword from 1209 to 1236. Schenk is sometimes appended to his name.

Originally from Naumburg, Germany, Volkwin succeeded Wenno von Rohrbach, the first master of the order. Volkwin led the Sword-Brothers in the Northern Crusades in Latvia and Estonia against the Samogitians, Curonians, Semigallians, and Selonians. He was ultimately killed by the Samogitians during the course of the Battle of Saule in 1236. The surviving Sword-Brothers were subsequently merged into the Teutonic Knights led by Hermann Balk and became an autonomous "sub-order".
