Polish-Lithuanian Commonwealth

Checked. And inb4 "muh Mongols conquered Russia" - sort of, but they never took Moscow, and the Muscovites grew in strength while the Mongols weakened - and went on to kick them out. Sort of like how most of Iberia was conquered by the Moors/Arabs - but not all of it, and that was all the Reconquista needed. Russia didn't take as long tho.
Lesson from history - finish what you start.

>Mongols
That's actually a point in my favor. Mongols conquered Kievan Rus which was decentralized and pretty liberal, at least by medieval standards.

Why were the Iberian Muslims called "Moors", and the African Muslims "Berbers"?

Liberum Veto is literally twitchplays of their time.

If you mean when exactly the possibility and the idea of a P-L state ended, then the answer is, as it often seems to be with medieval-born notions and ideas in Europe, in the 19th century, the latter part more specifically, and nationalism.

After two failed Polish rebellions, which the polonised Lithuanian nobility naturally took part in, the newly (re-)starting national awakening of Lithuanians was based on specifically on the peasants and (peasant) lithuanian culture. Deliberate effort was made to take stance against slavic culture and influences which included the Polish speaking Lithuanian (as in blood not in name only) aristocracy. And during the first years of the 20th century it was this nationalistic Lithuania which came out on top and realised the new independent Lithuanian State in its image. The Polish-Lithuanian war and the following frozen and unresolved conflict just cemented the already evolved situation and understanding.

Tl;dr IT WAS NATIONALISM

>It would have worked just without the Liberum Veto clause.
To be honest, the problem was the first time someone used Liberum Veto and left, because if the precedens of ending Sejm without doing anything wouldn't be established there (the head of Sejm should continue without him), then Liberum Veto would remain as it were before - vetoi'ng poseł would simply talk with others with possibility of being convinced of letting changes through.

>muh liberum veto
Everytime 1 or 2 nobles thought of cockblocking some decision they were bullied into voting like everyone else, so it wasn't as much of a shitshow as you'd think it should be

Berbers are an ethnic group you dink

Yet the Poles are still kicking. Seriously though, they and the Japs are some of the only peoples who won't be fully AngloAmericanized in a century. Plucky little bastards :).

Liberum veto was a symptom of decaying empire, not a cause that made it start to become degenerate
elective monarchy was mistake, in fact only two out of 9~ kings were competent and one of them ruled for a very short period of time. Sigimund Vasa was worst of them all seeing as he ruled for longest time and royally destroyed every single chance of making Poland a lot stronger and its enemies weaker.
Another problem was shift of rulling class from middle class majority to rich magnates which effectively made country playground of rich families in 18 century and again a lot of the blame on that problem can be pinpointed on shitty Vasa king.
Also the fact that economy was mostly dependant on grain didn't help when western countries started to diversify their food thanks to shit like tomatoes and potatoes from new world.

they got conquered by commies

also muh geographical position meme is sorta true, enemies were on pretty much every side even the idea of semi-friendly austria unifying germans and eventually possibly wanting prussian clay was fucking horrifying
fighting for useless eastern clay with Russia wasn't fun and productive either

Bump
