Editing Curzon Line (section)

===Characteristics===
The Northern half of the Curzon Line lay approximately along the border which was established between the  [[Prussian Kingdom|Kingdom of Prussia]] and the Russian Empire in 1797, after the [[Third Partition of Poland]], which was the last border recognised by the United Kingdom. Along most of its length, the line at least in principle was intended to follow a generally ethnic or ethnolinguistic boundary - areas West of the line generally contained an overall Polish majority while areas to its East less so- borderland areas were inhabited by [[Ukrainians]], [[Belarusians]], [[Polish people|Poles]], [[Jews]] and [[Lithuanians]].<ref>{{cite book|author=Zara S.
