Forms of Government and Political Systems: A Comparative Analysis
Chapter 1: Introduction to the Political System and Its Elements
1. The Political System and Its Study
Forms of political expression refer to the diverse ways humans have organized their political lives throughout history. These forms of political organization, comparable (with reservations) to the political system, encompass a broad spectrum of structures and processes.
Political science, as a modern discipline with its own sphere, object, specific methods, and differentiation, emerged in the late nineteenth and early twentieth centuries. It adopted an inductive approach based on observation and measurement, focusing on new themes such as power relations, political behavior of citizens and elites, attitudes, opinions, and political processes.
Over time, political science has undergone various shifts and influences, shaping how it approaches its complex and multifaceted object of knowledge.
The concept of the political system originates from systems theory, developed in sociology by Talcott Parsons. In the 1950s, David Easton introduced this paradigm to political science, moving away from the Parsonian view of the political arena as a subsystem of society. Easton (1973) proposed a conceptual framework based on an integrated set of categories to interpret empirically relevant political life as a system of conduct. The goal was to study how a system persists within its given political environment and reacts to influences and tensions.
A political system endures by fulfilling two fundamental functions: allocating values within a society and ensuring that its members accept these allocations as binding, at least most of the time.
The political system operates within a real environment (total ambient) crucial for its existence. This environment facilitates reciprocal interactions and exchanges, subjecting the political system to various influences, tensions, and disturbances. Easton’s analysis categorizes these influences as inputs (support for the political system and its authorities, if positive, and demands, if negative). The system responds to these influences by producing outputs, such as binding decisions and policies, which, in turn, impact the environment, generating feedback in the form of new inputs.
This circular process highlights the importance of information feedback for authorities. Understanding the effects of their decisions and reactions, as reflected in new inputs, is essential for formulating appropriate responses.
Studying this feedback loop helps explain how the political system copes with stress and reacts with new outputs, maintaining a level of support above the minimum necessary for its survival.
2. Form of Government and Political System
The term “form of government” has been used in various ways but now generally refers to the relationship between parliament and government in contemporary democratic regimes. This distinction primarily differentiates between parliamentary and presidential systems, with the semi-presidential model as a variant of the latter.
Parliamentary Systems
Parliamentary systems are characterized by a single institution (parliament) deriving legitimacy through direct election by citizens. The elected parliament determines the prime minister, who remains dependent on the confidence of the house. The prime minister, in turn, can typically dissolve parliament and call for new elections. This interdependence between the executive and legislative branches blurs the separation of powers in parliamentary systems.
In parliamentary systems, the government and parliament collaborate closely. The government requires parliamentary support for decision-making, while parliament scrutinizes and approves government-proposed laws and proposals from its members. This dependence is further reflected in parliamentary control mechanisms, such as written questions to the prime minister and votes of no confidence.
Collective cabinet responsibility is a common feature of parliamentary systems. The prime minister, enjoying the confidence of parliament, appoints ministers to form the cabinet. While the prime minister holds a prominent role, responsibility is shared collectively.
In most parliamentary systems, the head of state plays a largely symbolic role, primarily serving as an arbitrator and mediator between the executive and legislative branches.
Presidential Systems
there are two powers with direct legitimacy: the parliament (which has the legislative function) and President (State, which serves as the executive), elected by citizens in separate elections. There is a clear separation of powers. Thus, there is no parliamentary control mechanisms on the president, while he has no power to dissolve Congress and call new elections. The president has full authority to appoint members of the government, which sometimes have only the status of advisers, as only he is responsible for making policy decisions to the electorate.
The double source of legitimacy and distinct designation mechanism may lead to a scenario in which the parliamentary majority is of a different political persuasion than the president, which may lead to institutional blockages are solved, usually with the pre-eminence of parliament is able to veto legislative measures
