A fictional one. Basically, how and from where the money popped up is unknown, in a few short days the empire suddenly prospered to its glory days and the people had no complains over who'd run it.

In all honesty, it doesn't give us even the slightest of ideas as to what it is. It cannot be imperialism, that's what the revolutionaries were fighting against. Monarchism is still possible, although which kind is the true question here. One possibility is elective monarchism.
