Summary This article focuses on the Tacitist thought shared by Justus Lipsius and Hugo Grotius. Contrary to what his later works might suggest, in the years before the Dutch political crisis of 1618, Grotius appears willing to look at history and contemporary politics in terms of the Tacitist and reason-of-state-based categories defined in Lipsius's political works. A specific Lipsian inspiration seems present in Grotius's Amsterdam address of 1616, and his analysis of the early Dutch Revolt in the Annales et Historiae (...) is determined by categories of thought which at the time were identified with Lipsius's intellectual legacy.
