FAQ

A political regime is more than just an abstract concept in the realm of politics. It serves as the foundational blueprint that defines who wields power, how governments come to be selected, and the rules governing the exercise of political authority. While this may initially sound like a dry academic notion, the real fascination lies in its far-reaching implications for every aspect of political and social life.

Political regimes shape every facet of political life. Understanding their dynamics is crucial in a world where events like Russia's actions in Ukraine highlight the profound impact of regime type on domestic and international affairs. Va-PoReg empowers you to investigate critical questions, such as:

• What influences the stability and longevity of political regimes?
• What factors contribute to transitions between political regime types?
• How do political regimes impact economic development?
• How do political regimes shape a country's foreign policy and international relations?

Va-PoReg classifies political regimes into a wide range of types, including military, personalist, and one-party autocracies; communist and Islamist ideocracies as well as right-wing autocracies; autocratic and constitutional monarchies; non-electoral transitional regimes; electoral oligarchies; electoral oligarchical autocracies; electoral autocracies; electoral hybrid regimes; and electoral and liberal democracies. Additionally, there is a category for no central authority. We also consider whether a country is under direct or indirect rule through occupation or colonization.

The charts provide a visual representation of the global distribution of political regimes. They visually categorize political entities by regime type, showcasing the diversity and prevalence of these regimes across the dataset's political landscape. This facilitates an immediate grasp of the relative frequency and distribution patterns of regime types globally.

The second dimension of the charts illustrates the impact of these regimes on the global populace — visually representing the proportion of the world's population living under each regime type. This emphasizes the profound influence political regimes have on the lived experiences of individuals around the world.

You can find the codebook and dataset directly in the "dataset" section of our website. The codebook is essential — it explains all variables and coding procedures used in Va-PoReg. Be sure to download and read it before using the data in your research.

The dataset encompasses all political entities that have undergone periods of state sovereignty or at least a semi-sovereign status from 1900 to 2024. It includes states that navigated historical trajectories such as colonization, occupation, or incorporation into other sovereign entities — for example Lithuania or Ukraine during their affiliation with the Soviet Union. Our dataset includes dozens of cases like Newfoundland, Sikkim, or Tibet not covered by any existing political regime dataset.

Because incorporating territories introduces complexity, we present different variants of Va-PoReg for different purposes. We strongly recommend that researchers select the variant that aligns most effectively with their research objectives.

Detailed information on the coding of political regime categories can be found in the Va-PoReg codebook. This resource provides in-depth explanations of the methodology and criteria used to classify different types of political regimes, and is freely available in the dataset section of our website.

Our methodology for classifying countries into specific regime types is based on a comprehensive set of observable indicators detailed in our codebook. Each regime type is defined by a distinct combination of criteria related to electoral competition, suffrage, executive constraints, civil liberties, and the basis of regime legitimacy.

In the Va-PoReg dataset, for any year with a regime change — whether one or multiple — the regime type designated for the entire year is determined by the regime in place on July 1st. This methodology applies irrespective of the number of regime changes or the duration of each regime's rule within that year.

Transition dates are accurately documented in the dataset and detailed in the country reports, providing a consistent and precise framework for annual coding that facilitates comparison across different contexts and time periods.

Our dataset compiles data on political regimes through extensive research, including a review of academic literature and various online resources. Our primary source is the evaluation of qualitative research literature on individual countries; in cases not covered by other sources, this literature served as the sole data basis.

We prioritize transparency in our coding process, documented in detailed country reports. Our dataset also integrates insights from the Autocratic Regime Dataset (Geddes, Wright, Frantz), Freedom House, the Lexical Index of Electoral Democracy (LIED), Polity V, and Varieties of Democracy (V-Dem), alongside variables from other notable datasets like Political Institutions and Political Events (PIPE).

The visualizations — including both maps and charts — incorporate interactive features that enhance user engagement and the depth of analysis. These features enable users to refine their view by time frame, geographical region, or continent, offering a tailored exploration of the data. Interactive elements support both a global perspective on regime types and a detailed examination of individual countries' regime histories.

By clicking on a country on the map, users can access a comprehensive timeline that showcases the historical progression of regime types within that country since 1900.

Changes in political regimes are visualized through timelines for each political entity. By selecting a country on the map, you are taken to a comprehensive timeline that displays the country's regime changes from 1900 to the current year. These changes are distinguished using different colors for each regime type, facilitating easy recognition of regime transitions over time.

Yes, users can customize both charts and maps to concentrate on particular countries, regions, or time frames. This customization includes selecting specific years, time spans, continents, and regions, allowing for a highly personalized viewing experience.

The visualizations provide a clear means to observe trends in political regimes over time, both regionally and globally. They graphically represent changes such as democratization or autocratization, allowing for easy identification of these trends. Users can choose to view the data by regime type per country or per population, offering a deeper insight into the significance and impact of political regime shifts.

Certainly. Each type of political regime classified by Va-PoReg represents a distinct form of governance with unique characteristics and dynamics. The questions below provide detailed definitions of each category — from liberal democracies to colonial and occupation regimes. Refer to the Va-PoReg codebook for the full formal definitions and coding criteria.

A liberal democracy is characterized by free and fair elections, universal suffrage, robust checks and balances among branches of government, an independent judiciary, and a free media and civil society.

An electoral democracy is a political regime where free and competitive elections exist, but democratic principles are undermined by weak checks and balances, restricted civil liberties, and unequal political participation (such as only male suffrage).

An electoral oligarchy limits democratic participation to a select group, often through restricted suffrage or indirect elections, exemplified by regimes with racial or social exclusion.

An electoral hybrid regime is a political system that blends democratic features like competitive elections and pluralism with autocratic practices such as biased media, restricted civil liberties, and systemic advantages for incumbents, preventing it from meeting democratic standards. This regime type stands between electoral democracies and electoral autocracies.

A non-electoral transitional regime emerges from political crises or regime collapses without electoral legitimacy, serving as a temporary structure to guide transition without elections.

An electoral autocracy conducts multi-party or multi-candidate elections without genuine freedom or fairness, with the government minimally constrained by the legislature.

An electoral oligarchical autocracy conducts non-free and unfair elections with highly restricted suffrage, lacks political liberties, and operates without effective constraints on the executive.

No. If the monarch holds only symbolic power, we consider it a ceremonial monarchy and display the regime type that better resembles the political system — for example, a liberal democracy like Spain today.

We consider a regime a ruling monarchy when the country is governed by a hereditary monarch with supreme authority. We distinguish between autocratic and constitutional monarchies.

We consider a regime a constitutional monarchy if it has elections with at least male suffrage and at least a moderate level of constraints on the executive and political liberties. Otherwise, we classify it as an autocratic monarchy, since the monarch's executive can rule without public scrutiny and institutional checks.

A one-party autocracy is a regime in which only non-competitive elections are held. Either only one party is legally permitted, or, where more parties are allowed, voters are presented with a unified candidate list that offers no meaningful political alternatives.

Ideocracies justify power with a utopian, totalitarian ideology, aiming for a future perfection based on the laws of nature, history, or divine command. They reject pluralism, claiming infallibility and the right to reshape society. Ideocracies include communist, fascist, and Islamist systems.

A communist ideocracy justifies power through Marxist-Leninist ideology, aiming to build a utopian classless society. Its legitimacy derives from historical theory rather than popular approval, often manifesting as a de facto one-party regime.

This regime includes fascist ideocracies and right-wing corporatist autocracies, categorized by either fascist or vague corporatist ideologies. Fascist regimes are typically one-party systems — examples include Nazi Germany and Fascist Italy — while corporatist autocracies, like Spain under Franco, use corporate groups for societal control.

An Islamist ideocracy governs through Islamist ideology, merging religious and political elements to dictate public and private life based on Islamic principles. Its legitimacy comes from Islamic teachings, significantly integrating religion into the state.

Military autocracy claims legitimacy through the military's role as a rational, apolitical arbiter in times of crisis, often established by a coup. It operates without popular elections, though it may permit multi-party parliamentary elections.

Personalist autocracy centers power in a single ruler with no effective institutional constraints. It lacks multi-party executive elections and institutional mechanisms for leadership change, focusing on the ruler's indefinite tenure.

A colonial regime is controlled by a foreign power, with the colonized population having limited rights and autonomy. It is marked by economic exploitation and is considered permanent, unlike an occupation regime. We distinguish between direct and indirect colonial rule.

Colonies with indirect rule have a form of self-governance in which the local population elects representatives to a parliament. Under direct colonial rule, the colonizing power governs without such local representative institutions.

An occupation regime is directed by a foreign power through occupation institutions, creating administrative structures for governance. Unlike a colonial regime, occupation is typically regarded as temporary.

A direct occupation regime is governed entirely by the occupying power without local institutional authority. An indirect occupation regime includes a locally elected legislature with limited but real decision-making power.

A regime with no central authority exists when no identifiable central government is present, typically during extreme situations such as civil wars or state collapse.
