Systems of Governance

Presidential / Separated republics

These are systems in which a president is the active head of the executive branch of government and is elected and remains in office independently of the legislature. The following list includes democratic and non-democratic states:

Full presidential systems

In full presidential systems, the president is both head of state and head of government. There is generally no prime minister, although if one exists he or she serves purely at the pleasure of the president.

Afghanistan Argentina Benin Bolivia Brazil Burundi Cameroon Central African Republic Chad Chile Colombia Comoros Democratic Republic of the Congo Republic of the Congo Costa Rica Côte d'Ivoire

Cyprus Djibouti Dominican Republic Ecuador El Salvador Equatorial Guinea Gabon The Gambia Ghana Guatemala Guinea Guinea-Bissau Honduras Indonesia Iran (to some degree) Kenya

Kiribati Liberia Madagascar Malawi Maldives Marshall Islands Mexico Federated States of Micronesia Nauru Nicaragua Nigeria Palau Panama Paraguay Philippines Rwanda

Seychelles Sierra Leone Sudan Suriname Tanzania Togo Tunisia Turkmenistan Uganda United States of America Uruguay Venezuela Zambia Zimbabwe

Semi-presidential systems

In semi-presidential systems, there is usually both a president and a prime minister. In such systems, the President has genuine executive authority, unlike in a parliamentary republic, but some of the role of a head of government is exercised by the prime minister, who is also leader of the legislature.

Algeria Angola Armenia Azerbaijan Belarus Bosnia and Herzegovina Burkina Faso Cape Verde Egypt Finland France Georgia Guyana

Haiti Kazakhstan Republic of Korea Kyrgyzstan Lebanon Mali Moldova Mongolia Mozambique Namibia Niger Pakistan Peru

Romania Russia São Tomé and Príncipe Senegal Serbia Sri Lanka Republic of China (Taiwan) Tajikistan Ukraine Uzbekistan Western Sahara Yemen

Parliamentary republics

A parliamentary republic is a system in which a prime minister is the active head of the executive branch of government and also leader of the legislature. The president's degree of executive power may range from being reasonably significant (eg. Poland) to little or none at all (eg. Ireland). Where the president holds little executive power, their function is primarily that of a symbolic figurehead.

Albania Austria Bangladesh Bulgaria Croatia Czech Republic Dominica East Timor Estonia

Ethiopia Germany Greece Hungary Iceland India Ireland Iraq Israel

Italy Latvia Lithuania Macedonia Malta Mauritius Mauritania Montenegro Poland

Portugal Samoa Singapore Slovakia Slovenia Trinidad and Tobago Turkey Vanuatu

Mixed republican systems

Constitutional monarchies

Systems in which a prime minister is the active head of the executive branch of government and also leader of the legislature. The head of state is a constitutional monarch who only exercises his or her powers with the consent of the government, the people or their representatives.

Andorra Belgium Cambodia Denmark Japan Lesotho Luxembourg

Malaysia Netherlands Norway Spain Sweden United Kingdom (see also under Commonwealth realms)

Commonwealth realms

Constitutional monarchies, in which Queen Elizabeth II serves as head of state over an independent government. In each Realm, she acts as the monarch of that state, and is usually titled accordingly - for example, Queen of Australia. The Queen appoints a Governor-General to each country other than the United Kingdom to act as her representative. The prime minister is the active head of the executive branch of government and also leader of the legislature.

Antigua and Barbuda Australia The Bahamas Barbados Belize Canada Grenada Jamaica

New Zealand Papua New Guinea Saint Kitts and Nevis Saint Lucia Saint Vincent and the Grenadines Solomon Islands Tuvalu United Kingdom
