June 19, 1867.
Compared to Juarez, Maximiliano I can be said to have no political mindset or capability at all.
As a traditional monarch supported by Mexican conservative forces and Napoleon III, he greatly implemented the policies of the Republican Faction, while naively believing he could reconcile with his opponents, Juarez and other Republicans.
Juarez did not disappoint Maximiliano I. He seized the latter's pitiful naivety, quickly rose again, and has now imprisoned Maximiliano I.
If Ernst were the Emperor of Mexico, he would surely support the local conservatives, stabilize the French, and actively suppress the so-called revolutionaries.
As for the so-called reactionary forces, backward systems, and corrupt rule, it's just a joke. For instance, in the past life, many African small countries had leaders and governments rampant with corruption, causing public outrage and suffering. Yet, they still ended well.
