So, in my history of posting Polish history questions on this board, I've found myself sadly out of my depth. I was wondering if anyone could help me to understand how the royal elections, the Golden Privileges, the Sejm etc worked, and what might be the best way to get Poland to follow the example of the Western European nations (centralization, absolutization), preferably during the reigns of IMO the stronger kings (Sigismund II Augustus, Wladyslaw IV or Jan III Sobieski).
Also, how much the Liberum Veto would've paralyzed any possible reforms etc.
Any help welcome.
