Intermarium

Proposed country during World War I

Intermarium was a post-World War I geopolitical plan conceived by Józef Piłsudski to unite former Polish–Lithuanian Commonwealth lands within a single polity. The plan went through several iterations, some of which anticipated the inclusion of neighbouring states. The proposed multinational polity would have incorporated territories lying between the Baltic, Black, and Adriatic Seas, hence the name Intermarium.
