Having read a few of the topics on the board before I registered, I've seen a couple of questions and topics about Poland although only a few to my knowledge asking about a surviving Polish-Lithuanian Commonwealth. But here is a different question. What is the latest possible time(s) the Commonwealth can be saved? It can either be pre or post partitions, as an actual independent state or a foreign-dominated but still nominally independent one.
I have some ideas that perhaps making the throne hereditary would go a long way in helping.
