1.We had quarantee the rights of citizen - sadly,only gentry and partially townspeople.There is a fine distinction between a republic and a democracy.
Republics should have written constitutions that formalize the obligations and guarantee the rights of the citizenry.
Muh Democracy is just mob rule/covert oligarchic control writ large/with a nice label.
That and you being greedy and trying to gobble up lots of real estate populated by people that didn't really like you, like Hmelnitski.
And still, in some situations you need a strong executive, not a run by committee state.
The same goes for obligation - sadly,they paid the same money as in 1410 as tax,and gold lost most of its value.
Curse you,Spain !
And If our farmers remained free,Poland should never fall.
And taking away farmers right and turning them into serfs.Idiots though,that they could remain free in state full of half-slaves.Well,it worked only in greek city-states,not possible in any bigger state.
