The State of the Teutonic Order (German:Staat des Deutschen Ordens; Latin:Civitas Ordinis Theutonici), also called Deutschordensstaat (pronounced[ˈdɔʏtʃ ɔɐdənsˌʃtaːt]) or Ordensstaat (pronounced[ˈɔɐdənsˌʃtaːt]) in German, was a crusader state formed by the Teutonic Knights or Teutonic Order during the 13th century Northern Crusades along the Baltic Sea. The state was based in Prussia after the Order's conquest of the Pagan Old Prussians which began in 1230, but also expanded to include the historic regions of Courland, Gotland, Livonia, Neumark, Pomerelia and Samogitia. Its territory was in the modern countries of Estonia, Latvia, Lithuania, Poland, and Russia. Most of the territory was conquered by military orders, after which German colonization occurred to varying effect.
