Monarchies in Europe [SEP] Succession laws
The succession order is determined by primogeniture in most European monarchies. Belgium, Denmark, Luxembourg, the Netherlands, Norway, Sweden and the United Kingdom now adhere to absolute primogeniture, whereby the eldest child inherits the throne, regardless of gender; Monaco and Spain have the older system of male-preference primogeniture, while Liechtenstein uses agnatic primogeniture. In 1990, Norway granted absolute primogeniture to the Norwegian throne, meaning that the eldest child, regardless of gender, takes precedence in the line of succession. This was not, however, done retroactively (as, for example, Sweden had done in 1980), meaning that Haakon, Crown Prince of Norway continues to take precedence over his older sister.
