Long before fleets of container ships criss-crossed the world’s oceans, camel caravans and single-sail cogs transported regional goods across the world.

Connecting the World

Today’s interactive map, by Martin Jan Månsson, is a comprehensive snapshot of the world’s trade networks through the 11th and 12th centuries, which helped to connect kingdoms and merchants throughout Asia, Africa, and Europe. A confluence of interesting factors helped bring these markets together to encourage commercial activity:

Crusading’s Commercial Corollary

The First Crusade kicked off in 1096, sparking a trend that would have an undeniable economic and cultural impact on Europe and the Middle East. European fighters arriving in the Middle East came into contact with civilizations that were, in many ways, more advanced than their own. Merchants in the area had already been been trading with places further east, and demand for “exotic” goods shot up when crusaders returned to Europe with items both plundered and purchased. The maritime infrastructure used to deliver all those soldiers laid the groundwork for moving goods between ports along the Mediterranean. Some ports, such as Alexandria, had separate ports for Muslim and Christian ships, which helped create a more stable pipeline of trade.

The Growing Influence of Cities

The dissolution of the Byzantine Empire and the Italian Kingdom left a vacuum that allowed Italian coastal cities to claim prominent roles in regional trade. The port cities of Venice and Genoa were transporting crusading soldiers to the front lines, so becoming hubs of trade in the Mediterranean was a natural evolution. Their geographic locations were also ideal entry points for goods moving along inland European trade routes. In the 10th century, word of Ghana’s abundant gold supply spread to Middle East and actually triggered a rush by Muslim merchants to build connections in the region. A lucrative gold export industry encouraged the growth of cities to the south of the Sahara Desert, which formed critical links between Africa and the Mediterranean trade network.

Flying Cash

While Italian cities were cementing their role in Western trade, the Song Dynasty introduced an innovation that has important implications today: paper currency. Paper notes, known as flying cash, backed only by the government’s word, helped eliminate the need for heavy coinage and allowed trade to flourish in China. Later on, Marco Polo would famously deliver this idea back to Europe.

The Silk Road

“The Silk Road” is a catch-all term for the many overland and maritime routes linking East Asia with Europe and the Middle East. Cities and towns along busy Silk Road routes thrived, and during the 12th century, Merv (in present day Turkmenistan) was actually the largest city in the world until it was decimated in 1221 by the Mongol Empire. Trade routes like the Silk Road made the movement of physical goods possible, but perhaps more importantly, they facilitated cross-cultural exchange of ideas, religion, technology, and more. 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.
