Sambor II, Duke of Pomerania

His daughter Euphemia (also called Alenta or Iolanta or Adelheid) (born c. 1245 - died c. 15 February 1309) married Bolesław II the Horned in 1261.

After that Sambor founded a new Cistercian monastery, Samboria, located in present-day Pelplin.

[2] Sambor fought against his brother, Swantopolk II (Swietopelk), and allied himself with the Teutonic Order.

Sambor willed most of his possessions, including Gniew (Mewe), to the Teutonic Knights.

This permanently established the Teutonic Knights on the left bank of the Vistula River.
