Amidst whispers of Brexit and potential changes within NATO, you might be wondering how these organizations fit into the big picture of Europe’s member states. Europe has members in at least four major treaty groups, each of which governs a different aspect of the region’s infrastructure. Let’s break down each group:

European Union (EU)

The European Union is primarily a political organization. It promotes economic, social, and political cooperation among its member states, encompassing more than 510 million citizens. The last nation to join was Croatia in 2013, while the United Kingdom will be the first to officially withdraw on March 29, 2019. The EU is governed according to a supranational parliamentary system, with representatives elected by member states. The union maintains common policies on trade, agriculture, and regional development. It also enacts legislation on justice and home affairs, ensuring the free movement of people, goods, services, and capital within its borders. The EU was awarded the Nobel Peace Prize in 2017 for its contribution to the “advancement of peace and reconciliation, democracy, and human rights in Europe.”

North Atlantic Treaty Organization (NATO)

NATO is a military alliance between the United States, Canada, Turkey, and 26 other European countries. Established in 1949 as a response to post-WW2 Soviet aggression, NATO exists for the collective defense and security of the group. Members share few laws and regulations, but an attack on one constitutes an attack on all, and member states are obligated to act in defense of one another. Iceland remains the only member without armed forces. Their strategic geographic location earned them a spot as a founding member of NATO, but they have no standing army and joined on the condition they would never need to establish one.

Eurozone

The Eurozone is a monetary union of 19 EU nations which have adopted the Euro as their common currency. Established in 1999 to control inflation, the Eurozone is managed by a board of central banks, but members share no fiscal policies. The remaining EU members are obliged to adopt the Euro at some point in the future, except for the UK and Denmark, who are exempt and permitted to retain a unique currency. The Euro is also used in a number of non-EU states. Andorra, Monaco, San Marino, and Vatican City obtained formal agreements to issue and use their own Euro coins. Kosovo and Montenegro also adopted the Euro, but without formal permission, meaning they cannot legally issue currency.

Schengen

This grouping of 26 European states abolished passports and other types of border control at their mutual borders in 1995. For travel purposes, Schengen states function as a single country with a common visa policy. This visa doesn’t cover residency or work permits, but allows tourists and visitors to obtain a single visa for the entire area, making border restrictions virtually non-existent. While travellers face stringent controls when entering or leaving the Schengen zones, visa holders can pass between Schengen countries without a passport or ID. Monaco, San Marino, and Vatican City are not formally part of Schengen, but maintain open borders within the Schengen area. The map of Europe’s member states has changed constantly over thousands of years. As political shakeups continue and the United Kingdom prepares for their exit from the EU, it might be interesting to see how different this map looks a few years from now.

on 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: Let’s take a closer look at some of these systems.

Monarchies

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.

Republics

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.

One-Party State

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.

Provisional

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.
