How do dictators rise to power?

It results from a weakness in a government sometimes due to financial crisis which a dictator sees and takes advantage of. This usually happens with an uninfomed and uneducated public who is persuaded by the dictator. Once the dictator takes hold they rule by threats on peoples lives or livelyhoods so no one will confront them. Any one who confronts them is delt with quickly and severly so everyone else gets the message not to mess with them. The dictator knows if he or she lets opposition grow they will be gone.

Ex. Saddam Hussien, Hitler, Stalin the list is endless there are many today.
