Problem of two emperors

The Problem of Two Emperors is a problem that was first talked about hundreds of years ago. It's a way to describe a situation where two people both want to be in charge, but they can't both be in charge at the same time. So it's like a problem where two people want the same thing but can't both have it. The main problem is that if both people keep wanting the same thing then neither one of them will get it.
