A leader that rules by fear, alienates the mass public who then become too frightened to criticise or stand up for themselves.
Certain groups or individuals being publically ostracised, then black suited security people employed to protect the name of the glorious leader becoming heavy handed with ordinary everyday protesters.
A leader having taken land that does not belong to him, and trying to annex other pieces of land. A leader who can orate to the masses but delivers so very little to benefit those masses and then falls on their sword at the end leaving total chaos and destruction behind.
