The monarchy of Luxembourg is led by the grand duke of Luxembourg. The grand duke is the head of state for the country. Luxembourg became a grand duchy on March 15, 1815. It was once connected to the United Kingdom of the Netherlands until 1890. Luxembourg is special because it is the world's only independent grand duchy. Since 1815, there have been ten monarchs. The current Grand Duke is Guillaume V.

What the Grand Duke Does

The constitution of Luxembourg explains the grand duke's role. He is the head of state and a symbol of the country's unity. He also makes sure Luxembourg stays independent. The Grand Duke helps run the government according to the country's laws.

In December 2008, a change was made to the constitution. Before this, the Grand Duke had to formally approve new laws. Now, he still announces the laws, but his personal approval is not strictly needed for a law to pass.

How the Grand Ducal Family is Supported

The Grand Duke does not receive a salary. However, the grand ducal family gets money each year to help with their official duties. In 2017, about €10.1 million was set aside in the country's budget for the grand duke's household expenses.

Who Inherits the Throne?

The rules for who becomes the next Grand Duke or Grand Duchess are called "succession." For a long time, these rules mostly allowed only male family members to inherit the throne. This was part of an old family agreement called the Nassau Family Pact.

In June 2011, the rules changed. Now, any legitimate child, whether male or female, can inherit the throne. This means daughters have the same right to become Grand Duchess as sons have to become Grand Duke.

The person who is next in line to the throne is called the "hereditary grand duke" once they turn eighteen.

The Grand Dukes of Luxembourg

Luxembourg has had ten monarchs since 1815. They belong to two main royal families.

House of Orange-Nassau

This family ruled Luxembourg from 1815 until 1890. They were also the kings of the Netherlands at the same time.

House of Nassau-Weilburg

When William III died in 1890, he had no sons. The rules for the Netherlands allowed his daughter, Wilhelmina, to become queen. But the rules for Luxembourg were different. They said that only male family members could inherit the throne unless there were no males left. So, the crown of Luxembourg went to Adolphe, from a different branch of the Nassau family.

Later, in 1907, Grand Duke William IV had only daughters. He made a law to confirm that his eldest daughter, Marie-Adélaïde, could become Grand Duchess. She was the first female ruler of Luxembourg. After she gave up the throne in 1919, her younger sister Charlotte became Grand Duchess. Her descendants have ruled Luxembourg ever since.
