Cuba, Syria, and North Korea are three countries that have a dictatorship. Besides dictatorship there are many other forms of authoritarian government. As of today, 50 countries in the world are rated as "Not Free" by Freedom House.
Freedom House, an American non-governmental organization (NGO), rates each country based on their citizen's political rights and civil liberties, and labels them as free, partly free, or not free. Their most recent report names 50 countries as not free, including China, Russia, Iran, and Saudi Arabia. According to their research 36% of the world's population lives in a country that is not free.
Dictatorships date back to the times of Julius Caesar. There have been many rulers throughout history known for ruling with an iron fist including Benito Mussolini, Adolf Hitler, Joseph Stalin, Mao Zedong, and more recently Saddam Hussein.
