Dynasts
A ruler in a dynasty is sometimes referred to as a dynast, but this term is also used to describe any member of a reigning family who retains succession rights to a throne. For example, following his abdication, Edward VIII of the United Kingdom ceased to be a dynastic member of the House of Windsor.
A "dynastic marriage" is one that complies with monarchical house law restrictions, so that the descendants are eligible to inherit the throne and/or other royal privileges. For instance, the 2002 marriage of Willem-Alexander, Prince of Orange, to Máxima Zorreguieta was dynastic, and their eldest child is expected to eventually inherit the Dutch crown. But the marriage of his younger brother Prince Friso to Mabel Wisse Smit in 2003 lacked government support and parliamentary approval. Thus Friso forfeited his place in the order of succession and lost his title as a Prince of the Netherlands, and his children have no dynastic rights.
In historical and monarchist references to formerly reigning families, dynastic describes a family member who would have succession rights if the monarchy's rules were still in force. For example, after the 1914 assassinations of Archduke Franz Ferdinand of Austria and his morganatic wife Sophie von Hohenberg, their son Max was bypassed for the Austrian throne because he was not a Habsburg dynast. Even since abolition of the Austrian monarchy, Max and his descendants have not been considered the rightful pretenders by Austrian monarchists, nor have they claimed that position.
The term "dynast" is sometimes used to refer to agnatic descendants of a realm's monarchs, and sometimes to those who hold succession rights through cognatic royal descent. The term can therefore describe overlapping but distinct sets of people. For example, David Armstrong-Jones, Viscount Linley, a nephew of Queen Elizabeth II through her sister, Princess Margaret, is in the line of succession to the British crown: in that sense is a British dynast. Yet he is not a male-line member of the royal family, and is therefore not a dynast of the House of Windsor.
On the other hand, the German aristocrat Ernst August, Prince of Hanover (born 1954), a male-line descendant of George III of the United Kingdom, possesses no legal British name, titles or styles (although he is entitled to re-claim the once-royal dukedom of Cumberland), was born in the line of succession to the British crown and is bound by Britain's Royal Marriages Act 1772. Thus, in 1999 he requested and obtained formal permission from Elizabeth II to marry the Roman Catholic Princess Caroline of Monaco. But immediately upon marriage he forfeited his right to the British throne because the English Act of Settlement 1701 dictates that dynasts who marry Roman Catholics are considered "dead" for the purpose of succession.
