After World War II, the institution of the ombudsman began to spread primarily in today's democratic European countries, followed ba the rest of the world, in its development over time it adapted to the needs of different environments, this institution is present today in one form or another in a large number of countries with completely different cultural, political and legal traditions, i.e. with different legal and political arrangements. Due to the sudden advancement of civilization, in addition to the ever-widening spectrum of human freedoms and rights that need to be protected, during recent history there has been a need to establish other special institutions that would additionally control and regulate relations between the state and the individual, all with the aim of protecting numerous human freedoms and rights that could be violated by the authorities.
