Lieuwe Van Aitzema, a Dutch historian, born at Dokkum, Nov. 19, 1600, died at the Hague, Feb. 23, 1669. His great work is Zaaken van Stoat en Oorlog in Ende omtrent de Vereenigde Nederlanden (14 vols. 4to, 1657-71; 7 vols., 1669-72). It is chiefly valuable on account of the numerous original documents, referring to the period 1621-'68, which it contains. Aitzema was actively engaged in political affairs, and in his latter years was agent of the Hanseatic towns at the Hague.
