Authoritarianism can be talked about politically and psychologically. Here, however, we will focus on the political concept. Thus, authoritarianism is a system of non-party government, which rely on leaders, characterized by their charismatic authority. The army can also enjoy this authority in a given country.
We can speak of authoritarianism especially by looking at the history of Europe, that took place in the 20th century. It was then that the democratic system was slowly being created, but unfortunately it was not yet any success. Admittedly in governments, which are characterized by authoritarianism, one can talk about elections. However, these are not yet purely democratic elections, meaningful. Because in this case we cannot talk about any influence of the population assessment on political or legal matters.
Interestingly, power is actually meeting its goals by not really looking at what society has to say, but again, there is no question of any dictatorship here, which imposes horrible duties on people.
A lot of people are confused by the concept of authoritarianism, with totalitarianism and democracy. Usually they consider authoritarianism to be an intermediate direction between the two styles of government. In fact, the boundaries between them are somewhat blurring, but politicians have no problem distinguishing between these three forms of power, because for them these are quite significant differences.
