I feel like this is an extremely unpopular opinion but I really don't think republicanism was a step forward for humanity.
Monarchy is the most intuitive form of government. People tend to take care of what they own, and politicians have no incentive to leave anything better for the next generation because they really have no stake in their country. Their legacy dies with them.
A monarchy with constitutional (and familial) checks and balances is vastly preferable to a republic where the foreign interests run free and loot the taxpayers. It's pure and much simpler. No Congress, no Supreme Court, no ridiculous sham elections. Everyone knows who's in charge and what the rules are.
Just remember that it the Cabal almost 1666 years after Jesus, to start their plans to whittle down the monarchies.
They had to create a whole new country that was outside of monarchy.
They had to create multiple revolutions
They had to create two world wars
All so they could wipe out the monarchies that stood against their plans.
A monarch who strictly follows the God's laws and cares only about doing right by God and for their people, and can instill these ideals to all their heirs is the best form of governance.
The thing about monarchy , though, is that it has to be absolutely with divine blessing. How will that happen? What will it look like? We can only theorize.
