Queen Christina of Sweden, a patroness of scholars, desirous of aiding Grotius and of retaining him in the service of her kingdom, made many offers and promises, but their execution being deferred, he became impatient of his lot, refused a position as counselor of state, and resolved to leave the country. His plan to abandon Stockholm secretly was prevented by a messenger of the queen who followed him to the port where he intended to embark and induced him to return for a farewell audience. With a handsome present of money and silver plate he took passage on a vessel placed at his disposition to convey him to Lübeck. Off the coast near Dantzic a violent tempest arose. On the 17th of August, 1645, the vessel was driven ashore and Grotius, overcome by his trying experiences, was taken ill at Rostock, where a few days later he passed away. The later years of his life had been chiefly devoted to plans for the establishment of peace in the religious world, whose dissensions gave him great distress of mind. The country of his birth, which had so long denied him citizenship, received him at last to the silent hospitality of the tomb. His body was taken to Delft, his native town, where his name is now held in grateful reverence. At the time when Grotius left Stockholm, the last of the plenipotentiaries had arrived at Münster and Osnabrück to attend the great European congress convoked to terminate the hostilities of the Thirty Years' War. It is a tradition, but incapable of satisfactory proof, that it was with the purpose of being present at the councils of this congress that the author of "_De Jure Belli ac Pacis_" left Sweden for Germany. However this may be, it is certain that the mediation of the king of Denmark at Osnabrück and of the papal legate at Münster, though unsuccessful, was in accordance with the idea of Grotius expressed in the words: "It would be useful, and indeed it is almost necessary, that certain congresses of Christian powers should be held, in which controversies that have arisen among some of them may be decided by others who are not interested." The immediate establishment of an international tribunal, evidently contemplated in this suggestion, was not in harmony with the temper of those times; but it cannot be doubted that the Peace of Westphalia, whose treaties were to form a code of public law for Europe, was to a great degree an embodiment of the principles which Grotius was the first to enunciate.
