Because the new Terra trans Oderam, or "land across the Oder", formed an extension of the Margraviate of Brandenburg, it became known as the Neumark ("New March") after the middle of the 15th century.
Kuna uus Terra trans Oderam, või "maa üle Odra", moodustas Brandenburgi margi laienduse, sai see pärast 15. sajandi keskpaika tuntuks kui Neumark ("Uus mark").
