On St. George's Night (Estonian: Jüriöö ülestõus) 23 April 1343, the indigenous Estonian population in the Duchy of Estonia, the Bishopric of Ösel-Wiek and the insular territories of the State of the Teutonic Order tried to rid themselves of the Danish and German rulers and landlords, who had conquered the country in the 13th century during the Livonian crusade, and to eradicate the non-indigenous Christian religion. After initial success the revolt was ended by the invasion of the Teutonic Order. In 1346 the Duchy of Estonia was sold for 19,000 Köln marks to the Teutonic Order by the King of Denmark. The shift of sovereignty from Denmark to the State of the Teutonic Order took place on 1 November 1346.
