Which philosopher believed you could not overthrow your leader?

I am not sure if there was any such philosopher to pose something so vague, but I believe Hobbes mentions something to the case in the Leviathon along the lines that it would be ridiculous to do such a thing because one has made a social contract and to overthrow him would be to overthrow onesself. One could mearly dissmiss your leader instead by breaking the contract (ie. leave the country, secede...). But this may only pertain to cetain political situations. If it is a question of whether or not one will have the physical capacity to do such a thing... I have never read anything of the sort...
