Question: The Prussian Trust is registered in the capital city of what German state?

full_context: Document 1: Flight and expulsion of Germans (1944–50): During the later stages of World War II and the post-war period, German citizens and people of German ancestry were expelled from various Eastern European countries and sent to the remaining territory of Germany and Austria. After 1950, some emigrated to the United States, Australia, and other countries from there. The areas affected included the former eastern territories of Germany, which were annexed by Poland and the Soviet Union after the war, as well as Germans who were living within the prewar borders of Poland, Czechoslovakia, Hungary, Romania, Yugoslavia, and the Baltic States. The Nazis had made plans—only partially completed before the Nazi defeat—to remove many Slavic and Jewish people from Eastern Europe and settle the area with Germans. The post war expulsion of the Germans formed a major part of the geopolitical and ethnic reconfiguration of Eastern Europe in the aftermath of World War II, that attempted to create ethnically homogeneous nations within redefined borders. Between 1944 and 1948 about 31 million people, including ethnic Germans ('Volksdeutsche') as well as German citizens ('Reichsdeutsche'), were permanently or temporarily moved from Central and Eastern Europe.

Document 14: Prussia (region): Prussia (Old Prussian: "Prūsa", German: "Preußen" , Lithuanian: "Prūsija" , Polish: "Prusy" ) is a historical region stretching from Gdańsk Bay to the end of Curonian Spit on the southeastern coast of the Baltic Sea, and extending inland as far as Masuria. The territory and inhabitants were described by Tacitus in Germania in AD 98, where Suebi, Goths and other Germanic people lived on both sides of the Vistula River, adjacent to Aesti (further east). About 800–900 years later the Aesti were named Old Prussians, who since AD 997 repeatedly successfully defended against take-over attempt by the newly created Duchy of the Polans. The territory of the Old Prussians and neighboring Couronians and Livonians was unified politically in the 1230s as the Teutonic Order State. Prussia was politically divided in the period 1466-1772, with western Prussia under protection of the crown of Poland-Lithuania and eastern Prussia a Polish fief until 1660. The unity of both parts of Prussia remained preserved by retaining its borders, citizenship and authonomy until western and eastern Prussia were also politically re-united under the Kingdom of Prussia. It is famous for many lakes, as well as forests and hills. Since the military conquest by the Soviet Army in 1945 and the expulsion of the inhabitants it divided between northern Poland (most of the Warmian-Masurian Voivodeship), Russia's Kaliningrad exclave, and southwestern Lithuania (Klaipėda Region). The former German state of Prussia (1701–1947) derived its name from the region.
