Which royals are Catholic? A Look at Catholic Monarchies and Royal Families

For many Americans, the idea of royalty conjures images of crowns, palaces, and, perhaps most enduringly, the British Royal Family. However, when we ask "Which royals are Catholic?", the answer is more nuanced than simply pointing to one or two individuals. While historically, many European royal houses were staunchly Catholic, the landscape has shifted significantly over centuries, particularly with the rise of Protestantism. Today, the number of reigning monarchs who are Catholic is quite small, but there are still significant royal families with strong Catholic ties.

The United Kingdom: A Protestant Monarchy

The most prominent royal family in the English-speaking world, the British Royal Family, is explicitly Protestant. The British monarch is the Supreme Governor of the Church of England, a position that cemented the monarchy's Protestant identity after the Reformation. This means that the reigning monarch and their immediate heirs are required by law to be in communion with the Church of England.

Key points regarding the British Royal Family and Catholicism:

  • Historical Roots: The Church of England was established when King Henry VIII broke away from the Roman Catholic Church.
  • Act of Settlement (1701): This crucial piece of legislation still dictates that only Protestants can inherit the throne. This means that any royal who marries a Catholic does not lose their place in the line of succession, but a Catholic cannot be monarch.
  • Modern Policy: While there have been discussions and some reforms to succession laws (allowing succession even if a royal marries a Catholic), the monarch themselves must remain Protestant.

European Monarchies: A Mixed Bag

When we look beyond the UK, the picture becomes more diverse. Several European countries still have monarchs, and their religious affiliations vary.

Catholic Monarchies and Royal Families

While not all European monarchs are Catholic, there are still significant royal houses that adhere to the Catholic faith.

  • Spain: The current King Felipe VI of Spain and his family are Roman Catholic. Spain has a long and deep Catholic heritage, and the monarchy remains intrinsically linked to the faith. The Spanish constitution also recognizes the special role of Catholicism.
  • Belgium: The Belgian royal family, headed by King Philippe, is also Roman Catholic. Belgium is a predominantly Catholic country, and its monarchy reflects this.
  • Monaco: The Principality of Monaco is a sovereign state with a Catholic royal family. The Grimaldi family, including the current Prince Albert II, are practicing Catholics.

Other Royal Families with Catholic Connections

Even in countries that are not strictly Catholic monarchies, there can be significant Catholic members within royal families or those who have converted.

  • Luxembourg: The Grand Duke of Luxembourg and his family are Roman Catholic.
  • Liechtenstein: The Prince of Liechtenstein and his family are also Roman Catholic.

Historical Context: The Influence of the Reformation

It's important to understand the historical context that led to the current religious affiliations of royal families. The Protestant Reformation in the 16th century fractured the religious unity of Europe, and many monarchs chose to align with either the Catholic Church or the newly formed Protestant denominations.

The religious allegiances of royal families often became intertwined with political power and national identity. In some cases, embracing Protestantism was a way for rulers to assert independence from the Pope and the Catholic Church.

Why are some royal families still Catholic?

The continuation of Catholic traditions within royal families is often a reflection of the religious makeup of their respective nations and the historical development of their monarchies. In countries like Spain, Belgium, and Monaco, Catholicism has remained a dominant cultural and religious force, and the monarchy has evolved in tandem with these societal norms.

FAQ Section

How did the British Royal Family become Protestant?

The British Royal Family's shift to Protestantism was largely initiated by King Henry VIII in the 16th century. He sought to annul his marriage, which the Pope refused to grant. In response, Henry VIII declared himself the Supreme Head of the Church of England, breaking ties with the Roman Catholic Church. This marked the beginning of England's Protestant Reformation and cemented the Protestant identity of its monarchy.

Why are there still Catholic monarchies?

The existence of Catholic monarchies is due to a combination of historical continuity and the religious demographics of their countries. In nations like Spain, Belgium, and Monaco, Catholicism has remained the dominant religion or has held significant cultural influence. The monarchies in these countries have historically been, and continue to be, aligned with the Catholic Church, reflecting the traditions and values of their populations.

Can a royal marry a Catholic and remain in the line of succession in the UK?

Yes, under current laws, a member of the British Royal Family can marry a Catholic and remain in the line of succession. However, the monarch themselves must remain Protestant. This rule was a significant point of contention for centuries but was updated in 2013 with the Succession to the Crown Act, which removed the disqualification of a royal marrying a Catholic from the line of succession. The monarch, however, still must be in communion with the Church of England.

Are there any royal families that have converted to Catholicism?

While less common than a move away from Catholicism, there have been instances of royal figures or branches of royal families converting to Catholicism throughout history, often for political or personal reasons. However, in the context of current reigning monarchies, the trend has generally been towards maintaining existing religious affiliations or, in some historical cases, shifting towards Protestantism.


In conclusion, while the British monarchy stands as a prominent example of a Protestant royal institution, several other European royal families proudly adhere to the Catholic faith. The religious identity of royal houses is a fascinating reflection of history, culture, and the enduring influence of faith in shaping national narratives.
