Leaving out the fact that in all these examples it’s not like the monarchy preceding them was so much better. It seems that people are just not fond of royal bloodlines being in charge, and while previously limited communication options, education and inability to gather enough force to push them of their thrown themselves made it difficult for the people to destroy the institution of the throne, this is fortunately not the case anymore.
- The Shah regime had previously replaced a democratically elected government on behalf of the US and is infamous for its oppressive tendencies. The reason the people flocked to the mullahs was that they were pretty much the only force strong enough to dispose of it. The results for the Iranian people were (as much as I hate to say it) a net benefit at first, even if the theocratic government turned out to also be extremely authoritarian.
- Czar Nicholas of Russia was a poor leader with quite the authoritarian tendencies, and is therefore at least partially to blame for the Bolshevics to gain enough support to overthrow him.
- China’s monarchy was always a changing one, with the state splitting, refusing, splitting again more than a dozen times, with different warlords always going after control of either the entire region or parts of it. Saying that the monarchy provided stability here is naive at best. No one denies that the autocratic rule of the communists wasn’t and isn’t awful, but this only further proves that authoritarianism is bad overall, whether it’s in a monarchy or a dictatorship.
- The Weimar Republic was unstable mostly BECAUSE monarchists and other right-wing and conservative groups undermined it from the start, inventing the Dolchstoß myth, giving the Reichspräsident too much power to undermine the democratically elected parliament and make him a “quasi” king, etc. etc. Our current german state is a democracy, prosperous and stable and I wouldn’t have it any other way.
Overall you make a good point that authoritarianism leads to death and destruction. You fail to see though that absolute monarchies are not much better, if at all and that people disposed of them for a reason.
