I've been trying to search but have had no luck here or on the Wiki. Have there been any TLs focused on the Poland-Lithuanian Commonwealth in the 1700s?
If not, is it possible with a POD no later than 1750 for Poland-Lithuania to avoid being partitioned by the Austrians, Prussians, and Russians? What about no later than the War of the Polish Succession? Is it plausible for it to avoid the 2nd and 3rd partitions after the 1st?
