My meager memory - because I too am too lazy to go looking it up (actually more like, kind of busy here) is that the two aren't necessarily related. Despots usually seize power rather than have it granted or ceded to them.
People don't VOTE tyrants into power usually because if they did, they still possessed the power to remove them.
