The party system is a system of political parties, as well as their relationship with each other. Among the party systems, one-party, two-party and multi-party systems are distinguished. The latter are especially interesting for political scientists.
A multi-party system is a political system in which there is a variety of different political parties. Theoretically, they should have absolutely equal chances to get the majority of seats in the state parliament.
The basis of a multi-party system is the principles of freedom for education and their activities of various political parties, which are laid down in the Constitution.
The multiparty system indicates the presence in modern society of several different political parties, which must compete with each other due to their influence on the masses and enter the highest bodies of state power, that is, the legislative branch. Party system here is synonymous with a multi-party system.
A multi-party system can only be implemented in democratic societies that guarantee all their citizens equal rights in politics, including the organization of political forces. Here we can conclude that the concept of "multi-party system" is much broader than the concept of "multi-party system".
A multi-party system as a sum of political parties creates some negative phenomena in society. For example, the struggle for power of various political forces sometimes leads to its uncivilized forms. World experience shows that in the case of using a multi-party system in the country, many negative characteristics that arise in the case of using not the system, but simply the sum of parties, are removed.
The presence of many parties in a particular country does not yet mean that a multi-party system is functioning in this state. In these cases, the tasks facing an individual party and the party system as a whole do not coincide. After all, each party taken separately seeks to gain more and more political power and (or) greater control over its electorate, at a time when the multi-party system must ensure effective fulfillment of promises to the electorate, a balance in the representation of interests of various groups of the population in government bodies.
The sum of political parties can act as a multi-party system only in those cases when all of them will be in interdependent and mutually influencing relations. They should be guided by both formalized and unwritten rules in their political struggle, for example, the cornerstone principle of the rotation of political parties, the ability to find a compromise, positioning using ideological guidelines and the electorate group. Only if the above rules are observed can the theoretical sum of disparate parties be transformed into a dynamic and viable political structure. In this case, a multi-party system begins.
