Dutch nobility is regulated by act of law in the Wet op de adeldom (Law Regarding Nobility, passed into law on May 10, 1994) and is overseen by the Hoge Raad van Adel (High Council of Nobility), an official state institution of the Kingdom of the Netherlands.
Before 1814, the history of nobility was separate for each of the Dutch provinces. In the Early Middle Ages, there were, in each province, a number of feudal lords who often were just as powerful, and sometimes more so, than the rulers themselves. In old times, no title other than knight existed.
In the middle of the fourteenth century, quarrels between the feudal lords reduced many families and castles to ruins, contributing to the Dukes of Burgundys' acquisition by conquest or inheritance of many of the provinces forming the Kingdom of the Netherlands.
In 1581, representatives of the Seven Provinces abjured Philip II of Spain, heir of the Dukes of Burgundy. This left a great part of the executive and legislative power to the Ridderschap (knightly estate) of each province, which consisted of the representatives of those families of the old feudal nobility.
In 1795, the Batavian Revolution did away with their power, and it was not before 1813, when William I became King of the Netherlands, that they were again given power in another form. Still, by the time of the constitution of 1848, they had no influence in government affairs.
In 1813, if no higher title was recognised, the men only were to bear the hereditary predicate of Jonkheer. Some old feudal families obtained or assumed the title of Baron or Baroness for all their descendants.
Older nobility, having been granted their titles by either the Holy Roman Emperors or French Kings long before 1813, held their pre-existent titles, some of which were confirmed in the new Kingdom of the Netherlands (such as the families Bentinck, Limburg Stirum and Van Rechteren). In some of these families it is more usual that only the oldest male descendant bears the family title while other descendants bear the predicate of Jonkheer (m) or Jonkvrouw (f).
