One king to rule achievment (Poland)

[Nuggerath]

Can i be Commonwealth to make this achievement ?

If it is doable as Commonwealth - how to do it when i rejected "Niszawa Privileges" (I read somewhere that they should be accepted for further events which lead to "abolishing the sejm"). Can someone explain how to use pretender rebels to make this achievment

Well the Commonwealth does get all of the Polish events, on the other hand, it does say just Poland, not "Poland or the Commonwealth" probably because it can be formed by both countries. If I'd have to make a guess I'd say you need to be Poland, not the Commonwealth, to get the achievement, but that's just a shot in the dark, I haven't actually ever got the achievement.

You can do it as commonwealth yes, the Sejm keeps existing once you form the PLC. around 1605 two events will fire with nobles trying to take over the country, just let them rise up and defeat them. They are big stacks so make sure to have enough manpower or allies with good relations around that time. . Though in the new patch it might actually change a bit possibly

You only have to become an absolute monarchy, so if you get broken by revolutionaries or otherwise become a republic, then collapse back to monarchy, you can still get the achievement.

The only things that the achievement checks are that you started as Poland and that you eventually become an absolute monarchy. How you get there or what you form along the way doesn't matter (eg. Poland -> Prussia -> Russia -> HRE won't disqualify you). Hell, it'd probably be possible to pull it off by forming Westphalia (government becomes constitutional monarchy) and changing government the old-fashioned way or something, too.
