Robert van Asseliers (1576-1661), was from 1651 head of the civilian government of the duchy of Brabant as chancellor of Brabant.
Coming from a family of officeholders in the duchy of Brabant, Robert van Asseliers studied at the University of Leuven, graduating doctor of laws. In 1608 he married Antoinette Vandenberghe. Together they had a son and two daughters.
In 1619 Asseliers succeeded his father as a councillor of the Council of Brabant, and he went on to become a member of the privy council, the council of state, the supreme council of Flanders in Madrid, finally to be appointed chancellor of Brabant. Because of his advanced age, a vice-chancellor, Jean Thulden (brother of Diodorus Tuldenus), was appointed to help him in office.
