Harold Jul 09, 2026

The term "Crown Prince" is often associated with royal families and their heirs apparent. It's a title that carries significant historical and cultural weight, but how many crown princes are there in the world today? The answer is not as straightforward as one might think, as the number can vary depending on the definition and the source of information.

At its core, a crown prince is the heir apparent to a monarch. They are typically the eldest son of the reigning monarch, although this can vary depending on the laws of succession in each country. However, the number of crown princes can also include those who are not the direct heirs, but are next in line to the throne after the heir apparent.

Crown Princes in Europe

Europe is home to many monarchies, and thus, many crown princes. According to the Royal Central website, there are currently around 20 crown princes in Europe. This number includes those who are the direct heirs, as well as those who are further down the line of succession.

For instance, Prince William, Duke of Cambridge, is the crown prince of the United Kingdom. He is the eldest son of King Charles III and is next in line to the throne. Similarly, Prince Carl Philip is the crown prince of Sweden, being the eldest child of King Carl XVI Gustaf.

Crown Princes in Absolute Monarchies

Absolute monarchies, where the monarch holds all executive powers, have a single crown prince. For example, Saudi Arabia, which is an absolute monarchy, has a single crown prince. Currently, this position is held by Prince Mohammed bin Salman, who is the son of King Salman of Saudi Arabia.

In these monarchies, the line of succession is typically patrilineal, meaning that the throne passes from father to son. However, this can vary depending on the specific laws of succession in each country.

Crown Princes in Constitutional Monarchies

Constitutional monarchies, where the monarch's powers are limited by a constitution, can also have multiple crown princes. This is because the line of succession may not be strictly patrilineal, and may include female heirs. For example, in the Netherlands, Princess Catharina-Amalia is the crown princess, despite having younger brothers.

Moreover, in some constitutional monarchies, the line of succession may be determined by primogeniture, where the eldest child, regardless of gender, is the heir apparent. This is the case in Norway, where Crown Prince Haakon is the heir apparent to King Harald V.

Crown Princes in Asia and Africa

Asia and Africa are also home to several monarchies, each with their own crown princes. In Japan, for instance, Crown Prince Naruhito is the heir apparent to Emperor Naruhito. Meanwhile, in Morocco, Prince Moulay Hassan is the crown prince, being the eldest son of King Mohammed VI.

In the Middle East, countries like Kuwait, Bahrain, and Qatar also have crown princes. In Kuwait, Crown Prince Mishal Al-Ahmad Al-Jaber Al-Sabah is the heir apparent to Emir Nawaf Al-Ahmad Al-Jaber Al-Sabah.

Crown Princes in Islamic Monarchies

Islamic monarchies, where the monarch is also the head of state and the leader of the Muslim community, typically have a single crown prince. For example, in Malaysia, the Sultan of each state has a crown prince, who is usually the eldest son. However, this can vary depending on the specific laws of succession in each state.

In Brunei, meanwhile, Crown Prince Al-Muhtadee Billah is the heir apparent to Sultan Hassanal Bolkiah. He is the eldest son of the Sultan and is expected to succeed him as the Sultan of Brunei.

In conclusion, the number of crown princes in the world today is not a straightforward figure. It can vary depending on the definition of a crown prince, the laws of succession in each country, and the type of monarchy. However, it's clear that the title of crown prince is an important one, carrying significant historical and cultural weight. As the world continues to evolve, so too will the role of these crown princes, and the monarchies they represent.
