 The years of the brothers' "joint" reign were in spent in more-or-less constant conflict with both the Gediminids of Lithuania and with their own nominal overlords, the Mongol-Tatars of the Golden Horde.Lev II and Andrew established firm relations with the Polish High Duke (King) Władysław I (Władysław the Short or Elbow-high; also known as Ladislaus I of Poland, ) and, as already pointed out above, with the crusading knights of the Teutonic Order, as well as striving to lessen the ties of their kingdom's subservience to the Golden Horde.They were also in union with the allies of King Władysław I - the Scandinavian Kings and the Pomorian Dukes, against the Margraves of Brandenburg (1315).
