Danish Estonia
Northern Estonia was conquered by Danish crusaders led by king Waldemar II, who arrived in 1219 on the site of the Estonian town of Lindanisse (now Tallinn) at (Latin) Revelia (Estonian) Revala or Rävala, the adjacent ancient Estonian county. The Danish Army defeated the Estonians at Battle of Lyndanisse.
The Estonians of Harria started a rebellion in 1343 (St.George's Night Uprising). The province was occupied by the Livonian Order as a result. In 1346, the Danish dominions in Estonia (Harria and Vironia) were sold for 10 000 marks to the Livonian Order.
