why it is not possible for all the countries of the world to have the same party system, i.e. single or multi party system?
Answers
one-party state, single-party state, one-party system, or single-party system is a type of state in which one political party has the right to form the government, usually based on the existing constitution.[1] All other parties are either outlawed or allowed to take only a limited and controlled participation in elections. Sometimes the term de facto one-party state is used to describe a dominant-party system that, unlike the one-party state, allows (at least nominally) democratic multiparty elections, but the existing practices or balance of political power effectively prevent the opposition from winning the elections.
A political science college textbook explains the scholars generally agree that realignment theory identifies five distinct party systems with the following approximate dates and major parties. Sometimes two party systems have been seen as preferable to multi party systems because they are simpler to government with less fractiousness and greater harmony since it discourages radical minor parties while multi party systems can sometimes lead to hung parliaments.
