Where was Poland on the map during World War I and how did it reappear again in World War II?

Poland and Lithuania were united into one country in the 16th century. Later that country got weak and Prussia, Austria and Russia split its territory and divided it among themselves by 3 separate acts that each took place within a few year gap. Most of Poland was imilated into Prussia, including Warsaw. Napoleon has had turned some of territories around there into Duchy of Warsaw. The country was soon annexed by Russia. It regained independence when the Treaty of Versailles (peace treaty with Germany after WW1) was signed. It didn't reappear in WW2 but rather during the interwar period.
