GROEN VAN PRINSTERER, GUILLAUME (1801 1876), Dutch politician and historian, was born at Voorburg, near The Hague, on Aug. 21, 18o1. He studied at Leyden university, and acted (1829-33) as secretary to King William I. of Holland. He became the leader of the so-called anti-revolutionary party, both in the second chamber, of which he was for many years a member, and outside. In Groen the doctrines of Guizot and Stahl found an eloquent exponent. They permeate his controversial and political writings and historical studies, of which his Handbook of Dutch History (in Dutch) and Maurice et Barnevelt (in French, 1875, a criticism of Motley's Life of Van Olden-Barnevelt) are the princi pal. Groen was violently opposed to Thorbecke, whose principles he denounced as ungodly and revolutionary. He died at The Hague on May 19, 1876. He is best known as the editor of the Archives et correspondance de la maison d'Orange (12 vols., a great work of patient erudition.
