Valdemar II of Denmark
From its foundation, the indisciplined Order tended to ignore its supposed vassalage to the bishops. The desires of the Swordbrothers to expand to the north of Daugava river, along the Livonian Aa stream, brought the Order into confrontation with Bishop Albert. Albert wanted to extend to the south of the river and didn't have an interest in Estonia, previously promised to King Valdemar II of Denmark.
