Diplomacy is a very demanding and respected discipline that has been practiced since ancient times by people who had to possess extensive knowledge and the ability to negotiate and influence other people. The founding of the most important international organization, the United Nations, led to the adoption of the Vienna Convention on Diplomatic Relations from 1961 as an treaty that codified the existing customary law on diplomatic relations. Its adoption significantly contributed to the protection of diplomatic representatives in international relations so that they could perform their functions as freely as possible. The Convention stipulates the rights and obligations of diplomatic representatives and receiving states, as well as their privileges and immunities. Diplomatic privileges and immunities are guaranteed to diplomatic representatives while they are in the receiving state, and a very important role is played by the personal inviolability of the diplomatic representative, the inviolability of the premises of the diplomatic mission, but also immunity from criminal, civil and administrative jurisdiction of the receiving state and freedom of communication. The purpose of this thesis is to provide an insight into diplomatic privileges and immunities through various practical examples with the aim of better understanding the diplomatic profession and its importance.
