西布格河
The Bug River land (, "Trans-Bug land") is land which was within the territory of interbellum Poland (Second Polish Republic) and was forcibly vacated by Polish landowners after 1945 when the territory ceased to be inside Poland. The name refers to the Bug River because the Bug forms a major part of the new eastern boundary of Poland largely based on the Curzon Line, separating the so-called Eastern Borderlands from the rest of current Polish territory. The Bug River land is today distributed between the states of Belarus, Lithuania, and Ukraine. The claims for compensation for this sequestered land are known as the Bug River claims.
