A dictatorship is a unitary form of government characterized by a single leader or group of leaders and little or no toleration for political pluralism or independent programs or media. According to other definitions, democracies are a form of government in which "those who govern are selected through contested elections"; therefore, dictatorships are "not democracies".

With the advent of the 19th and 20th centuries, dictatorships and constitutional democracies emerged as the world's two major forms of government, gradually eliminating monarchies, one of the traditional widespread forms of government of the time. Typically, in a dictatorial regime, the leader of the country is identified with the title of dictator; although, their formal title may more closely resemble something similar to leader. A common aspect that characterized dictatorship is taking advantage of their strong personality, usually by suppressing freedom of thought and speech of the masses, in order to maintain complete political and social supremacy and stability. Dictatorships and totalitarian societies generally employ political propaganda to decrease the influence of proponents of alternative governing systems. - Wikipedia
