Elections are a way of not having civil wars. Ideally the election result should be indicative of who would win a civil war, so you can get to the outcome a civil war would produce without all the killing and destruction. If you allow women and blacks and people without property etc to vote, then the election result is likely to fail to reflect the likely outcome of a civil war. If women and people without property get too grabby, a civil war then is incentivized, in that white men of property would be substantially better off with the civil war outcome than the election outcome

If one faction or the other then burns the Reichstaag, providing a schelling point on which a civil war can be started, the incentivized civil war becomes likely.
