Mapping The World’s Legal Government Systems
With over 200 countries existing across the world with unique cultures and traditions, one might assume that there are hundreds of types of government systems. But both historically and in modern times, that’s not the case.
Even while political regimes across these countries have changed over time, they’ve largely followed a few different types of governance. Today, every country can ultimately be classified into just nine broad forms of government systems.
This map by Truman Du uses information from Wikipedia to map the government systems that rule the world today.
Countries By Type of Government
It’s important to note that this map charts government systems according to each country’s legal framework.
Many countries have constitutions stating their de jure or legally recognized system of government, but their de facto or realized form of governance may be quite different.
Here is a list of the stated government system of UN member states and observers as of January 2023:
|Country||Constitutional form||Head of state|
|Antigua and Barbuda||Constitutional monarchy||Ceremonial|
|Bahamas, The||Constitutional monarchy||Ceremonial|
|Bosnia and Herzegovina||Republic||Ceremonial|
|Central African Republic||Republic||Executive|
|China, People's Republic of||Republic||Ceremonial|
|Congo, Democratic Republic of the||Republic||Executive|
|Congo, Republic of the||Republic||Executive|
|New Zealand||Constitutional monarchy||Ceremonial|
|Papua New Guinea||Constitutional monarchy||Ceremonial|
|Saint Kitts and Nevis||Constitutional monarchy||Ceremonial|
|Saint Lucia||Constitutional monarchy||Ceremonial|
|Saint Vincent and the Grenadines||Constitutional monarchy||Ceremonial|
|São Tomé and Príncipe||Republic||Executive|
|Saudi Arabia||Absolute monarchy||Executive|
|Solomon Islands||Constitutional monarchy||Ceremonial|
|Trinidad and Tobago||Republic||Ceremonial|
|United Arab Emirates||Constitutional monarchy||Executive|
|United Kingdom||Constitutional monarchy||Ceremonial|
|Vatican City||Absolute monarchy||Executive|
Let’s take a closer look at some of these systems.
Brought back into the spotlight after the death of Queen Elizabeth II of England in September 2022, this form of government has a single ruler. They carry titles from king and queen to sultan or emperor, and their government systems can be further divided into three modern types: constitutional, semi-constitutional, and absolute.
A constitutional monarchy sees the monarch act as head of state within the parameters of a constitution, giving them little to no real power. For example, King Charles III is the head of 15 Commonwealth nations including Canada and Australia. However, each has their own head of government.
On the other hand, a semi-constitutional monarchy lets the monarch or ruling royal family retain substantial political powers, as is the case in Jordan and Morocco. However, their monarchs still rule the country according to a democratic constitution and in concert with other institutions.
Finally, an absolute monarchy is most like the monarchies of old, where the ruler has full power over governance, with modern examples including Saudi Arabia and Vatican City.
Unlike monarchies, the people hold the power in a republic government system, directly electing representatives to form government. Again, there are multiple types of modern republic governments: presidential, semi-presidential, and parliamentary.
The presidential republic could be considered a direct progression from monarchies. This system has a strong and independent chief executive with extensive powers when it comes to domestic affairs and foreign policy. An example of this is the United States, where the President is both the head of state and the head of government.
In a semi-presidential republic, the president is the head of state and has some executive powers that are independent of the legislature. However, the prime minister (or chancellor or equivalent title) is the head of government, responsible to the legislature along with the cabinet. Russia is a classic example of this type of government.
The last type of republic system is parliamentary. In this system, the president is a figurehead, while the head of government holds real power and is validated by and accountable to the parliament. This type of system can be seen in Germany, Italy, and India and is akin to constitutional monarchies.
It’s also important to point out that some parliamentary republic systems operate slightly differently. For example in South Africa, the president is both the head of state and government, but is elected directly by the legislature. This leaves them (and their ministries) potentially subject to parliamentary confidence.
Many of the systems above involve multiple political parties vying to rule and govern their respective countries.
In a one-party state, also called a single-party state or single-party system, only one political party has the right to form government. All other political parties are either outlawed or only allowed limited participation in elections.
In this system, a country’s head of state and head of government can be executive or ceremonial but political power is constitutionally linked to a single political movement. China is the most well-known example of this government system, with the General Secretary of the Communist Party of China ruling as the de facto leader since 1989.
The final form of government is a provisional government formed as an interim or transitional government.
In this system, an emergency governmental body is created to manage political transitions after the collapse of a government, or when a new state is formed. Often these evolve into fully constitutionalized systems, but sometimes they hold power for longer than expected.
Some examples of countries that are considered provisional include Libya, Burkina Faso, and Chad.

Ranked: Share of Global Arms Exports in 2022
The U.S. is the biggest weapons exporter in the world, but which other countries take up a significant share of global arms exports in 2022? And how has that share changed over time?
Ranked: Share of Global Arms Exports 2018–2022
In 2022, global military budgets hit $2.2 trillion, an eighth consecutive year of increase.
Part of those budgets were used for the procurement of arms, but which countries are major weapons suppliers, and how do they influence the global arms trade?
We chart out the top 10 countries with the biggest share of global arms exports using data from the Stockholm International Peace Research Institute (SIPRI).
Which Country Exports the Most Weapons?
The U.S. is the biggest weapons exporter, accounting for 40% of the total volume of international arms transfers between 2018–2022. Nearly one-fifth of these exports headed to Saudi Arabia, and other significant amounts went to Japan (8.6%) and Australia (8.4%).
Below we rank the biggest weapons exporters by share of total volume traded in 2018–2022, as well as their growth or decline from trends recorded in 2013–2017.
|Rank||Country||% share of global arms exports|
|% change between
2013-17 & 2018-22
|9||🇰🇷 South Korea||2%||+74%|
|N/A||🌐 Rest of World||9%||N/A|
Russia (16%) and France (11%) rank close together, followed by China (5%) and Germany (4%) to round out the top five major arms exporters.
However France’s export volumes grown considerably (+44%) from the previous five-year period, thanks to big sales to India, which included 62 combat aircraft and four submarines, one-third of all French weapons trade. This has resulted in France leapfrogging the U.S. as India’s second-largest weapons supplier after Russia.
On the other hand, Russia’s exports by volume has decreased (-31%) even before sanctions kicked in after the invasion of Ukraine. Its biggest trade partners, India and China, have prioritized developing their own weapons industries.
South Korea’s Surging Weapons Exports
Another country whose arms sales are skyrocketing is South Korea, which ranks 9th in the overall share of global arms exports, but has seen a 74% increase in its export volumes. Key recipients include the Philippines, India, and Thailand.
South Korean president Yoon Suk Yeol has pledged to grow his country into the world’s fourth largest arms exporter by 2027.
Interestingly, South Korea is one of three countries which is both a top-10 arms exporter and importer (along with China and the U.S.) as it has many takers for domestically produced military equipment, while simultaneously being reliant on American-produced long-range missiles and advanced combat aircraft.
