What is the earliest time the Polish-Lithuanian Confederation can be partitioned by other countries?
The Second Northern War goes very bad and PLC is divided between Russia (most of Lithuania and Ukraine), Sweden (Pomerelia with Gdańsk/Danzig, Courland), Brandenburg/Prussia (parts of western Poland, Warmia). A rump of former PLC remains, probably as Kingdom of Poland.

Why are you so mean to Poland?On a more serious note, I think the earliest the commonwealth could collapse is the 17th century.
