The State of the Teutonic Order (German: Staat des Deutschen Ordens; Latin: Civitas Ordinis Theutonici), also called Deutschordensstaat (German: [ˈdɔʏtʃ ɔɐdənsˌʃtaːt]) or Ordensstaat[2] ([ˈɔɐdənsˌʃtaːt]) in German, was a crusader state formed by the knights of the 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. It expanded to include at various times Courland, Gotland, Livonia, Neumark, Pomerelia and Samogitia.
