Isaac Dorislaus

Isaac Dorislaus (1595 in Alkmaar, Holland – 2 May 1649 at The Hague, Holland) was a Dutch Calvinist historian and lawyer who was an important official in Oliver Cromwell's period of rule. He came to England as a historian. His lectures were seen as political rhetoric, with references to kings with unjustified power aimed at portraying the reigning monarch, Charles I of England, as a tyrant. Little was done about his propagandizing, however. Dorislaus became advocate general of the army in the first civil war, and for all his previous theorizing about ancient liberties, quickly showed authoritarian tendencies by his attempted introduction of martial law to help him root out Royalists. He is remembered for his part in the High Court of Justice for the trial of Charles I, although his role was not prominent, and he was assassinated by Royalists while on a diplomatic mission in his native country. Dorislaus, a Hollander in English service, was appointed by Parliament as ambassador in addition to Strickland. A few days after his arrival, he was murdered by Royalists seeking to avenge Charles I's death. Provided by Wikipedia
