This paper seeks to explain what communication is, what types of communication we know and what is the importance of non-verbal communication as such, and especially body language. Body language is an important factor in communication, especially today when we have access to a wealth of literature and papers, when the field of body language communication has been sufficiently scientifically researched to be able to see the importance of such communication. Nonverbal communication makes up 50-60% of communication. Every gesture, movement, facial expression carries its own meaning and affects the communication itself. People who skillfully manage body language skills usually find it easier to influence interlocutors because of their credibility and the cohesion of what is said and the body. Synonyms for eloquent people are usually politicians in high positions and people in high social positions who are exposed in the media and who often know how to be attacked by the public precisely because of the mismatch of non-verbal cues and words. Inconsistency usually implies irrelevance of information and unreliability. It also describes the historical importance of public appearances, the chronological sequence of the development of communication, starting from ancient times when the great speakers were a pillar of society, all the way to modern personalities. Public appearances are also marked by styles in which a certain goal is to be achieved, while some do not care about the consequences of their actions, some pay very skillful and selective attention to every word spoken. Political speeches are often the subject of expert analysis. Any information uttered in a public space has a certain weight symbolism and the speaker must be aware of the possible consequences. The ability of public speaking is not only a rich vocabulary, but also the ability to cope in unfamiliar environments, among unknown people and prompt coping in awkward situations. Through examples of great leaders or at least candidates for great leaders, their shortcomings are shown, certain advantages that body language indicates and the end result that was directly influenced by body language itself.
