Answer:
Absolute rulers of dictators as they are usually called, rule by the decree. In other words all power is centered on them and they rule the nation as they see fit.
There is a saying by Lord Acton that goes like, "Power tends to corrupt; absolute power corrupts absolutely". This is because when most of these dictators become dictators they become fantastically corrupt. They loot state resources and clamp down on dissent. They deny people their basic liberties and they run inefficient governments that do not care much for the people.
They even have a tendency of favouring a certain tribe or section of the population over others.
When these feelings or mistreatment and inequality reach a boiling point, people tend to stage riots and protests. This is what happened across the Arab world in 2011 in what was called The Arab Spring and more recently in Sudan last year.
The people took to the streets demanding equality and basic freedoms which were denied to them by the Absolute rulers. When most of their demands were not met, they turned to violence and revolution. Libya, Syria and Yemen were plunged into Civil War and have no recovered since. In Libya and Yemen the revolution worked in part as the former leaders were replaced. Tunisia and Egypt, both of whom managed to avoid war also saw their long time Absolute leaders fall. Sudan, last year saw months of protest against it's long term leader, the culmination of which was his removal from power by his own army.
All these instances described were driven by the ordinary citizens of the country who were tired of the way they were treated in the society. They wanted Liberty. They wanted Equality. They wanted good Government. And they wanted Freedom. These concepts drove them to fight and in most cases overcome, their absolutes.
