The 10 Richest Kings in the World

King Maha Vajiralongkorn

Would you believe that 10 of the wealthiest people in the world are actually Kings? Even more surprisingly, 6 of those 10 were voted in rather than inheriting their royal titles. These kings have something else in common — their kingdoms are tiny. The smallest country per capita is Monaco, with a population of just over 30,000. On our list, you will find a number of European countries including Monaco and Liechtenstein which have small populations but rich economies due to tourism and exports of goods like watches or wine. Certain properties such as oil reserves can also be attributed to some countries' wealth; for example, Saudi Arabia's economy relies on its vast oil reserves. It is also interesting to note that some of these kings don't actually rule their own countries, but rather they inherited the title. Thailand's King Vajiralongkorn is considered the world's most hardworking monarch as he never takes a day off from his duties. So, let's take a look at the richest kings in the world!

10. Tamim bin Hamad Al Thani, Emir of Qatar Net Worth: $2.1 billion - $1.2 billion

No. 10 on the list of richest Kings is the Emir of Qatar, Tamim bin Hamad Al Thani. He succeeds his father who was a former Emir from 1995 to 2013. Tamim’s net worth is estimated to be between $2.1 billion and $1.2 billion, making him one of the richest men in the Middle East. His wealth is estimated to be generated from Qatar's vast oil and natural gas reserves, at least $120 billion in net foreign assets, and from the country's economic growth since the mid-2000s.

9. Juan Carlos I, King of Spain, King of Spain (abdicated in 2014) Net Worth: $2.3 billion - $2 billion

Technically, Juan abdicated in 2014 and passed the mantle to his son but, in the absence of an up to date value of the current king (Felipe VI), “King” Juan Carlos is the closest we have. The current monarch likely has similar wealth. Juan Carlos I was King of Spain since the death of Francisco Franco in 1975. With a net worth between $2.3 billion and $2 billion, Juan Carlos is one of the richest men in Europe.

8. Grand Duke Henri of Luxembourg, Grand Duke of Luxembourg Net Worth: $4 billion

Henri is Grand Duke of Luxembourg. The Grand Duchy of Luxembourg is a small European country that is best known as the home of the European Court of Justice. The duchy's other major economic activity involves steel, chemicals, and electronics manufacturing. The Grand Duke's fortune was made in part by his family's holdings in ArcelorMittal (one of the world's largest steel companies), as well as in SBM Offshore (an oil and gas service provider) and Banque Internationale a Luxembourg (a bank). His personal net worth stands at $4 billion, which makes him one of the richest men in Europe.

7. Mohammed bin Rashid Al Maktoum, Prime Minister of the United Arab Emirates, Emir Sheikh of Dubai Net Worth: $4 billion

No. 7 on the list of richest Arab men is Sheikh Mohammed bin Rashid al Maktoum. He is considered the driving force behind Dubai and has vast business interests in the Middle East, Europe, and North America. With a personal fortune of $4 billion, he has a stake in numerous companies, including Dubai World (worth $4 billion), DP World (worth $2 billion), Danube Flotilla (worth $2 billion), and others. He also owns various hotels around the world such as The Burj Al Arab, but he is perhaps best known for his role as an effective businessman in the financial sector since his reign with Dubai Financial Market started in 1971.

6. Mohammed VI, King of Morocco Net Worth: $5.7 billion - $2.1 billion

Mohammed VI is the current King of Morocco. He was born in 1957 and ascended to the throne in 1999.

Mohammed VI recently embarked on an ambitious plan, known as ‘Casablanca Valley’, to build a new city containing an international airport, a Formula 1 racetrack, sports venues, and hotels among others. His net worth is estimated at $5.7 billion by Forbes (2015) while Business Insider estimates it to be closer to $2.1 billion.

5. Hans Adam II, Prince of Liechtenstein Net Worth: $5 billion - $3.5 billion

There is a dispute over the net worth of Prince Hans-Adam II. Forbes lists his net worth as $5 billion (2011) while other sites claim his net worth to be closer to $3.5 billion.

His wife Princess Marie-Aglae has no official title.

4. Khalifa bin Zayed Al Nahyan, President of the United Arab Emirates, Emir of Abu Dhabi Net Worth: $15.0 billion

Khalifa bin Zayed Al Nahyan is the President of the United Arab Emirates. He was also the Emir of Abu Dhabi from 2004 to 2014. He is a member of the Abu Dhabi branch of the Nahyan family. The President's net worth comes from his father who served as ruler of Abu Dhabi for over 50 years before him. The President has assets in oil, gas, and investments including real estate and financial services. One of his largest holdings is an investment company, Aabar Investments PJS. Khalifa bin Zayed Al Nahyan has a son and three daughters. His son Tamim bin Hamad Al Nahyan is the current Crown Prince of Abu Dhabi and effective ruler of the Emirate.
