That's interesting, I hadn't considered a parallel with Constantine. I was asking AI about Julius Caesar earlier this year and I saw parallels that seemed similar to Trump. Below are key parts that stood out to me

""" Why millions of Romans loved or admired [Caesar]

He fought for the populares cause: land reform for poor veterans, debt relief, citizenship for provincials, cheaper grain.

Soldiers adored him—he shared their hardships, remembered every man’s name, and paid massive bonuses out of his own pocket.

The urban poor in Rome literally rioted when he was murdered; they burned the Senate house and hunted the assassins.

Many provinces (especially Gaul and Spain) saw him as the man who brought them into the Roman system with rights, not just conquest.

He pardoned almost all of his defeated enemies (including Brutus and Cassius)—an act of clemency that was almost unheard-of in Roman civil wars. (That mercy is part of why his murder shocked people so much.)

....

So was he power-hungry and arrogant?

Yes—absolutely. He was ambitious on a scale almost no Roman had ever dared before. But he was also:

Genuinely convinced that the old Republic was broken and corrupt (which it was—the Senate had been paralyzed by bribery and violence for decades).

Trying to fix real problems (veterans with no land, provinces treated like cash cows, a political system that rewarded gridlock). """
