We arranged them based on the length of their reign.

*The traditional religion of the Dutch royal family is Dutch Reformed Church which is now part of the Protestant Church in the Netherlands (a merger of the Dutch Reformed Church, Reformed Churches in the Netherlands, and the Evangelical Lutheran Church).
Unlike King Charles III, King Willem-Alexander is not required to belong to a specific church, although Dutch royal family is historically Protestant.
