Members of the Belgian royal family, other than the monarch, hold the title of Prince or Princess of Belgium, with the style of
Royal Highness. Prior to the
First World War, they used the additional titles of Prince or Princess of Saxe-Coburg and Gotha and Duke or Duchess of Saxony, as members of the
House of Wettin. The title Prince or Princess of Belgium is a specific noble title within the
Belgian nobility reserved for members of the Belgian royal family. Originally the Royal Decree of 14 March 1891 reserved this title for all persons descending in the direct male line from king
Leopold I. The royal decree also automatically granted the title to the princesses who joined the Belgian royal family by their marriage to a Prince of Belgium. This royal decree was amended by the Royal Decree of 2 December 1991, which reserved the title for the direct male and female descendants of
Albert II and abolished the Salic Law with regards to its granting. The Royal Decree of 12 November 2015, published in the
Belgian official journal on 24 November 2015, abolished the aforementioned Royal Decree of 1991, and restricts new grants of this title to the children and grandchildren of the reigning monarch, and to the children and grandchildren of the crown prince(ss). The spouse of a Prince or Princess of Belgium is no longer automatically granted the title but he or she can still be granted the title by royal decree on an individual basis. Prior to this, all descendants of Albert II were entitled to the title of prince or princess.
