Comparative Political Systems & Forms of Government
Comparative politics examines the institutional mechanisms, constitutional rules, and distribution of state power across various governance systems. Democratic models are broadly divided into Parliamentary systems (such as the United Kingdom, India, and Canada), where executive leadership derives legitimacy from and remains accountable to the legislature, and Presidential systems (such as the United States and Brazil), characterized by a strict separation of powers and a directly elected chief executive with fixed tenure. Semi-presidential systems, like France, combine a directly elected president with a prime minister responsible to parliament. States are further distinguished by vertical power distribution into Federal systems (constitutional power sharing) and Unitary systems (centralized power delegation).
Key Concepts & Examination Highlights
- In a Parliamentary system, the executive is drawn from the legislative branch and remains collectively responsible to it under the principle of fused powers.
- In a Presidential system, the principle of separation of powers and checks and balances ensures independence between the executive and legislative branches.
- Federal states (such as the United States, India, and Germany) feature constitutional division of powers between central and regional/state governments.
- Unitary states (such as the United Kingdom, France, and Japan) concentrate supreme governing authority within a single central national government.
