It is commonly believed that a country's politics shall reflect the design of its culture. However, sufficient support for this statement has not been found. This study employs the development of political party system of Indonesia to examine how true the statement is. Since the independence, Indonesia's party system has transformed from the multiparty system to the one-party system and then again back to the multiparty system. By conducting a historical-comparative study, it is found that in Indonesia, the transformation of the form of the party system has nothing to do with her political culture. In fact, political culture was more like a convenient mean manipulated by the rulers to secure their political position or to realize their political ambition.
