Valdemar II of Denmark
The Battle of Lyndanisse (also spelled the Battle of Lindanise) was a battle during the Livonian Crusade, fought between the Kingdom of Denmark with various German allies and pagan Estonian tribes. The battle helped King Valdemar II of Denmark establish the territory of Danish Estonia during the Northern Crusades, which were undertaken in response to calls from the Pope. The Danes defeated the Estonians at Lindanise (, today Tallinn).
