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 20th century. 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, influencing how it approaches its complex and multifaceted object of knowledge. The notion of a political system, originating from systems theory developed in sociology by Talcott Parsons, was introduced to political science by David Easton in the 1950s.

Easton (1973) proposed a conceptual framework grounded in an integrated set of categories, allowing for the empirical interpretation of political life as a system of conduct. His aim was to study how a system persists within a given political environment, reacting to influences and tensions. According to Easton, a political system endures by fulfilling two basic functions: assigning values within a society and ensuring that its members accept these allocations as binding.

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 reacts to these influences by generating outputs, such as binding decisions and policies, which, in turn, impact the environment, prompting further inputs. This circular process highlights the importance of information feedback for authorities to understand the effects of their decisions and reactions, enabling them to respond adequately to new inputs.

Understanding this feedback loop is crucial for explaining how political systems cope with stress and react with new outputs, maintaining a level of support necessary for their survival.

2. Form of Government and Political System

The expression “form of government” encompasses various meanings but currently denotes the relationship between parliament and government in contemporary democratic regimes. This distinction primarily differentiates parliamentary and presidential systems, with the semi-presidential model emerging as a variant of the latter.

Parliamentary Systems

Parliamentary systems are characterized by a single institution, the 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, highlighting the close relationship between the executive and legislative branches and blurring the separation of powers.

In parliamentary systems, government and parliament collaborate closely. The government requires parliamentary support for decision-making due to its dependence on the legislature. Consequently, parliament scrutinizes and approves government-proposed laws and proposals from its members. This dependence is further reflected in parliamentary control mechanisms, ranging from written questions to the prime minister to formal inquiries and votes of no confidence.

Collective cabinet membership is a defining feature of parliamentary systems. The prime minister, enjoying parliamentary confidence, typically 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

Presidential systems feature two directly legitimized powers: the parliament (legislative function) and the president (head of state and executive branch), both elected separately. This clear separation of powers means no parliamentary control mechanisms exist for the president, who cannot dissolve Congress or call new elections. The president holds full authority in appointing government members, who may sometimes function as advisors, as the president bears sole responsibility for policy decisions before the electorate.

The dual sources of legitimacy and distinct designation mechanisms in presidential systems can lead to scenarios where the parliamentary majority and the president belong to different political persuasions. This can result in institutional gridlock, often resolved by the parliament’s ability to veto legislative measures.
