Curzon LineThe Curzon Line was a proposed demarcation line between the Second Polish Republic and the Soviet Union, two new states emerging after World War I. Based on a suggestion by Herbert James Paton, it was first proposed in 1919 by Lord Curzon, the British Foreign Secretary, to the Supreme War Council as a diplomatic basis for a future border agreement. The line became a major geopolitical factor during World War II, when the USSR invaded eastern Poland, resulting in the split of Poland's territory between the USSR and Nazi Germany along the Curzon Line.
Pale of SettlementThe Pale of Settlement (Черта́ осе́длости (pre-1918 spelling (Черта́ осѣдлости)), chertá osédlosti; דער תּחום-המושבֿ, der tkhum hamóyshev; תְּחוּם הַמּוֹשָב, t'ẖum hammosháv) was a western region of the Russian Empire with varying borders that existed from 1791 to 1917 (de facto until 1915) in which permanent residency by Jews was allowed and beyond which Jewish residency, permanent or temporary, was mostly forbidden. Most Jews were still excluded from residency in a number of cities within the Pale as well.
Radziwiłł familyThe House of Radziwiłł (raˈd͡ʑiviww; Radvila; Радзівіл, Radzivił; Radziwill) is a powerful magnate family originating from the Grand Duchy of Lithuania and later also prominent in the Crown of the Kingdom of Poland. The family was founded by Radvila Astikas, but over time it split into many branches, such as the Biržai-Dubingiai and Goniądz-Meteliai lines. However, most of the branches became extinct by the 18th century, with only the Nesvizh-Kleck-Ołyka line surviving to this day.
