1. The Five Most Common Political Systems around the World
What are the most common types of political systems?

2. Types of political systems
Each political system has its advantages and disadvantages
It is worth considering the merits of other political systems, and perhaps incorporating some of the ideas into your own system

3. Democracy
A democracy in a more traditional sense is a political system that allows for each individual to participate

4. Democracy Direct Democracy Representative Democracy
Many scholars point to Athens as an example of direct democracy
Technically, every citizen has an equal say in the workings of government
Citizens could show up at a meeting, and then directly participate in the governing process, and the process of making laws.
citizens elect representatives who actually make the law
representatives called electors make the decision
although designated electors usually vote according to the wishes of the citizens in their states

5. Democracy Deliberative democracy
citizens approach decision making by considering different viewpoints and options, as well as democratic socialism
citizens help make decisions or vote for policies that are socialistic in nature.

6. (2) Republic
a republic is a political system in which the government remains mostly subject to those governed
Some scholars define any political system in which the citizens legitimize the government
a representative democracy (or any form of democracy) might be considered a republic

7. Republic Some of the types of republics that you might see include:
Crowned republic
Single Party
Capitalist
Federal
Parliamentary

8. Republic parliamentary system
 is a system of democratic governance of a state in which the executive branch derives its democratic legitimacy from, and is held accountable to, the legislature (parliament); the executive and legislative branches are thus interconnected.
In a parliamentary system, the head of state is normally a different person from the head of government 
Countries with parliamentary systems may be constitutional monarchies, where a monarch is the ceremonial head of state while the head of government is almost always a member of the legislature (such as the United Kingdom, Sweden and Japan)

9. Republic Crowned republic
is a form of constitutional monarchy where the monarch's role is ceremonial and all the royal prerogatives are prescribed by custom and law in such a way that the monarch has little or no discretion over governmental and constitutional issues
 Norway, Canada, Australia and the United Kingdom

10. Republic single-party
A single-party state, one-party state, one-party system, or single-party system is a type of state in which a single political party has the right to form the government, usually based on the existing constitution
People's Republic of China, Cuba,  Laos,  Vietnam, Eritrea

11. Republic
Capitalist
is an economic system in which trade, industry, and the means of production are privately owned and operated via profit and loss calculation (price signals) through the price system. Central characteristics of capitalism include private property, capital accumulation, wage labor and, in some situations, fully competitive markets. In a capitalist economy, the parties to a transaction typically determine the prices at which they exchange assets, goods, and services.

12. Republic
Federal
a type of government characterized by both a central (federal) government and states or regional governments that are partially self-governing; a union of states.

13. (3) Monarchy
a ruler is not usually chosen by the voice of the people or their representatives
Often a monarch is the head of state until he or she abdicates or until death
there are different types of monarchies

14. Monarchy the absolute monarchy
in which the monarch truly has the ultimate say in matters of government
most monarchies in political systems today do not follow this method
Many of them, especially in the developed world, have limits. Constitutional monarchies fall into this category
The U.K., Denmark, Kuwait, Spain, Sweden

15. (4) Communism
a communist state is based on the ideology of communism as taught by Marx and/or Lenin
Communist states are often dominated by a single party, or a group of people

16. (5) Dictatorship a dictator is the main individual ruling the country.
he or she makes most of the decisions, and usually has enforcers
In some cases, the political system is run by a small group of people
Dictators are not restricted by constitutions or parliaments.
