If we study governments and political systems on the basis of a series of similar and consistent patterns and patterns, Europe has always seen a set of interconnected political units that has created the most interconnection and closeness over time. One of the features of European politics and government has been the development of democratic ideas, institutions and mechanisms known as "Western democracy" with its advantages and disadvantages. The House of Representatives is also one of the main institutions of democracy and the most solid pillar of the liberal democracy system, formed in various forms and functions in European governments.
In practice, different historical backgrounds and different political and social traditions have shaped various forms of parliamentary structures in Europe. Accordingly, the present paper seeks to examine the various forms of public representation and expression of the will of the legislature and the parliamentary system in Europe. The main questions of the article seek to understand whether the institutionalization of the role of popular representation within the structure of monocameralism is closer to the principles of democracy, or in the form of non-democracy (bilingualism). Also in the bicameral system, is the supremacy of the supreme parliaments or the real power of the national parliaments? In fact, given the dynamics of European societies combined with national and political diversity, both the mono-structure and the bureaucratic representationalism are representative of the regime and have no democratic advantage over the other. In many ways, including the political heritage and historical tradition of many European countries, we are witnessing the formation of a two-chamber structure composed of the Supreme and National Assembly. In this case, the two chambers have never had the same weight and authority, but the one elected directly by the people has more superiority and credibility than the one whose representatives are appointed or indirectly appointed. It is therefore assumed that the existence of two chambers of parliament will create some balance in the legislative branch.
