ReichsautobahnThe Reichsautobahn system was the beginning of the German autobahns under Nazi Germany. There had been previous plans for controlled-access highways in Germany under the Weimar Republic, and two had been constructed, but work had yet to start on long-distance highways. After previously opposing plans for a highway network, the Nazis embraced them after coming to power and presented the project as Hitler's own idea. They were termed "Adolf Hitler's roads" ("Straßen Adolf Hitlers") and presented as a major contribution to the reduction of unemployment.
Crown of the Kingdom of PolandThe Crown of the Kingdom of Poland (Korona Królestwa Polskiego; Corona Regni Poloniae) was a political and legal idea formed in the 14th century, assuming unity, indivisibility and continuity of the state. According to this concept, the state ceased to be the patrimonial property of the monarch or dynasty, but became a common good of the political community of the kingdom. Such an idea allowed the state to function even in periods of interregnum and led to the formation of a system characteristic of Poland based on the parliamentarism of the nobility and the free election of the ruler.
Klaipėda RevoltThe Klaipėda Revolt took place in January 1923 in the Klaipėda Region (also known as the Memel Territory or Memelland).

It was placed under provisional French administration until a more permanent solution could be worked out. Lithuania wanted to unite with the region (part of Lithuania Minor) due to its large Lithuanian-speaking population of Prussian Lithuanians and major port of Klaipėda (Memel) – the only viable access to the Baltic Sea for Lithuania.
