A Fascinating Map of Medieval Trade Routes



Globalization is so well established in today’s world that we don’t think twice about where our bananas or socks come from.

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.

Visualized: The Biggest Ponzi Schemes in Modern History

Learn the stories behind some of the world’s biggest Ponzi schemes in this illustrative infographic timeline.



The Biggest Ponzi Schemes in Modern History

Some things simply sound too good to be true, but when money is involved, our judgement can become clouded.

This is often the case with Ponzi schemes, a type of financial fraud that lures investors by promising abnormally high returns. Money brought in by new members is used to pay the scheme’s founders, as well as its earlier investors.

The scheme is named after Charles Ponzi, an Italian who became infamous in the 1920s for claiming he could double his clients’ money within 90 days. Since then, numerous Ponzi schemes have been orchestrated around the globe.

To help you learn more about these sophisticated crimes, this infographic examines some of the biggest Ponzi schemes in modern history.

Ponzi Schemes in the 20th Century

The 1990s saw a number of large Ponzi schemes worth upwards of $500 million.

CountryDate EndedName of Scheme and FounderValue (USD)
Belgium1991Moneytron, Jean-Pierre Van Rossem$860M
Romania1994Caritas, Ioan Stoica$1B - $5B
Russia1994MMM, Sergei Mavrodi$10B
U.S.1997Great Ministries International, Geral Payne$500M

In many cases, these schemes thrived by taking advantage of the unsuspecting public who often lacked any knowledge of investing. Caritas, for example, was a Ponzi scheme based in Romania that marketed itself as a “self-help game” for the poor.

The scheme was initially very successful, tricking millions of people into making deposits by offering the chance to earn an 800% return after three months. This was not sustainable, and Caritas was eventually unable to distribute further winnings.

Caritas operated for only two years, but its “success” was undeniable. In 1993, it was estimated that a third of the country’s money was circulating through the scheme.

Ponzi Schemes in the 21st Century

The American public has fallen victim to numerous multi-billion dollar Ponzi schemes since the beginning of the 21st century.

CountryDate EndedName of Scheme and FounderValue (USD)
U.S.2003Mutual Benefits Company, Joel Steinger$1B
U.S.2003Petters Group Worldwide, Tom Petters$4B
U.S.2008Madoff Investment Scandal, Bernie Madoff$65B
U.S.2012Stanford Financial Group, Allen Stanford$7B

Many of these schemes have made major headlines, but much less is said about the thousands of everyday Americans that were left in financial ruin.

For victims of the Madoff Investment Scandal, receiving any form of compensation has been a drawn-out process. In 2018, 10 years after the scheme was uncovered, a court-appointed trustee managed to recover $13 billion by liquidating Madoff’s firm and personal assets.

As NPR reported, investors may recover up to 60 to 70 percent of their initial investment only. For victims who had to delay retirement or drastically alter their lifestyles, this compensation likely provides little solace.

Do the Crime, Pay the Time

Running a Ponzi scheme is likely to land you in jail for a long time, at least in the U.S.

In 2009, for example, 71-year-old Bernie Madoff pled guilty to 11 federal felonies and was sentenced to 150 years in prison. That’s 135 years longer than the average U.S. murder conviction.

Outside of the U.S., it’s a much different story. Weaker regulation and enforcement, particularly in developing countries, means a number of schemes are ongoing today.

Sergei Mavrodi, known for running the Russian Ponzi scheme MMM, started a new organization named MMM Global after being released from prison in 2011. Although he died in March 2018, his self-described “social financial network” has established a base in several Southeast Asian and African countries.

If you or someone you know is worried about falling victim to a Ponzi scheme, this checklist from the U.S. Securities and Exchange Commission (SEC) may be a useful resource.

The Top 100 Companies of the World: The U.S. vs Everyone Else

Where are the top 100 companies of the world located? We highlight the U.S. share of the top companies by market capitalization .



Top 100 Companies World vs US Shareable

The Top 100 Companies of the World: U.S. vs Everyone

When it comes to breaking down the top 100 companies of the world, the United States still commands the largest slice of the pie.

Throughout the 20th century and before globalization reached its current peaks, American companies made the country an economic powerhouse and the source of a majority of global market value.

But even as countries like China have made headway with multi-billion dollar companies of their own, and the market’s most important sectors have shifted, the U.S. has managed to stay on top.

How do the top 100 companies of the world stack up? This visualization pulls from PwC’s annual ranking of the world’s largest companies, using market capitalization data from May 2021.

Where are the World’s Largest Companies Located?

The world’s top 100 companies account for a massive $31.7 trillion in market cap, but that wealth is not distributed evenly.

Between companies, there’s a wide range of market caps. For example, the difference between the world’s largest company (Apple) and the 100th largest (Anheuser-Busch) is $1.9 trillion.

And between countries, that divide becomes even more stark. Of the 16 countries with companies making the top 100 ranking, the U.S. accounts for 65% of the total market cap value.

🇮🇪 Ireland2$0.34T
🇦🇺 Australia1$0.16T
🇩🇰 Denmark1$0.16T
🇨🇦 Canada1$0.13T
🇧🇪 Belgium1$0.13T

Compared to the U.S., other once-prominent markets like Japan, France, and the UK have seen their share of the world’s top 100 companies falter over the years. In fact, all of Europe accounts for just $3.46 trillion or 11% of the total market cap value of the list.

A major reason for the U.S. dominance in market values is a shift in important industries and contributors. Of the world’s top 100 companies, 52% were based in either technology or consumer discretionary, and the current largest players like Apple, Alphabet, Tesla, and Walmart are all American-based.

The Top 100 Companies of the World: Competition From China

The biggest and most impressive competitor to the U.S. is China.

With 14 companies of its own in the world’s top 100, China accounted for $4.19 trillion or 13% of the top 100’s total market cap value. That includes two of the top 10 firms by market cap, Tencent and Alibaba.

Impressively, China’s rise in market value isn’t limited to well-known tech and consumer companies. The country’s second biggest contributing industry to the top 100 firms was finance, once also the most valuable sector in the U.S. (currently 4th behind tech, consumer discretionary, and health care).

Other notable countries on the list include Saudi Arabia and its state-owned oil and gas giant Saudi Aramco, which is the third largest company in the world. Despite only having one company in the top 100, Saudi Arabia had the third-largest share of the top 100’s total market cap value.

As Europe continues to lose ground year-over-year and the rest of Asia struggles to keep up, the top 100 companies might become increasingly concentrated in just the U.S. and China. The question is, will the imbalance of global market value start to even out, or become even bigger?
