The cities and towns west of the Curzon Line were predominantly Polish.  The rural population represented
various ethnic groups in numbers far greater than found in urban cities.  Southern Poland had a large
Ukrainian population, but of Galician descent.

After World War II, Poland acquired new territory to the west, which included Silesia, Pomerania, Lubus Land,
Warmia, and Masuria.  These were the provinces originally part of eastern Germany and from which German
inhabitants were expelled after the war.
