Since the beginning of human history people lived together in communities; therefore, they needed system of organization. They started living in tribes with a leader who was the most capable member of the tribe. This lead to advanced systems of organization and it was developing into new ways how to manage specific groups of people. As the time passed people lived in bigger groups which needed new ways of governing people. These were the times in ancient history of human kind with big kingdoms ruled by kings with absolute power, supported by small group of people called aristocracy. During the ages people were developing new ideas how to rule and they developed new systems trying to find better and equal ways how to rule. As the people started to be more educated they tried to change their destiny and to be able to decide what the majority wants. So the first system which was considered to be equal for everybody was republic practiced in ancient Rome. After these experiments people lived for a long time under pressure of aristocrats where there were no chances for people to make decisions who would rule them. They often tried to change things by revolutions which were not successful. With the industrial revolution and new ways of living the system of monarchies and aristocracy became old. People became more powerful and the masses came to word. People like Marx and Engel's believed that it is possible to create society of people where everybody will be equal. Those theories were the basic of socialism which lead to communism which was the taken and practiced by the Russians in former Soviet Union and Eastern Europe. Although there were some advantages of this system it didn't worked and people realized that they cannot be equal in everything. In the Czech Republic (former Czechoslovakia) people realized that it is not possible to be prosperous with communist system and in 1989 there was a revolution called "The velvet Revolution".
