About the lecture
In 1625, 400 years ago, the child prodigy (with 11 years a student in Leiden, with 15 years dr. juris) and later a famous author of works about political theory and law, Hugo Grotius (1583-1645), published the famous work De jure belli ac pacis (On the Law of War and Peace, Paris 1625). This work had, for the first time, clearly formulated the general rules on ocean waters; therefore Grotius was called “the father of international law”. His first attempt to this was Mare Liberum (The Free Sea, Leiden 1609), where he argued that the Portuguese and the Spanish were not the only nations “to rule” over world’s seas. From now on the Dutch, fighting against the Spanish imperium, had broken its monopoly position. This was the beginning of the Dutch Golden Age.
The Wrocław University Library is a perfect venue for this lecture, as here (in the Old Prints Department) a magnificent collection of books from the 16th and 17th century is to be found (more than 300.000 works; one of the biggest collections in Europe); among them also works of Grotius, even with a dedication of his own hand.
