The ferment in mens minds having subsided, and the face of affairs being changed in Holland, Peter Grotius was nominated Pensionary of Amsterdam in 1660; which important place he filled for seven years with great reputation. This office was the height of Hugo's wishes for his son. The Count D'Estrade, at that time Ambassador from France in Holland, was dissatisfied with the Pensionary of Amsterdam, who opposed the interest of the French King, in resentment of that Prince's having driven Mombas, Peter Grotius's brother-in-law, out of France. Feb. 1, 1633, he writes to the King, "I have not been at Amsterdam, because the Pensionary M. de Groot is brother-in-law to M. de Mombas, whom your Majesty ordered to quit the kingdom for some affair in which you were dissatisfied with his conduct: since that time M. de Groot has constantly opposed your Majesty's interest at Amsterdam. He is a man of spirit and firmness; and has much credit in that city. I shall neglect nothing to bring him back to his former sentiments." The King answered him, May 23, 1633, that he had had reason to be dissatisfied with Mombas's conduct; that if any consideration could make him forget it, it would certainly be a regard for M. de Groot, whose person, says the King, I esteem: In fact, Lewis XIV, as he writes to his Ambassador, Sept. 22, 1665, dropt his resentment against Mombas out of consideration for the Pensionary of Amsterdam. After the conclusion of the triple alliance, the necessity of regulating the subsidies with the northern powers induced the States of Holland to send Grotius to Denmark and Sweden. He went first to Copenhagen, and afterwards to Stockholm, where he assumed the quality of Ambassador in ordinary. The States used only to keep a Minister of the second rank at this Court; but it was thought proper, says Wicquefort, to do something more than common for such an extraordinary person; and he was ordered to make a splendid entry at the expence of the States. The fourth volume of M. de Wit's _Letters and Negotiations_ concludes with the correspondence of Peter Grotius with the Grand Pensionary during his embassy at Stockholm. The Dutch Minister discovers in it great knowledge of mankind. "The more I reflect, says he to M. de Wit, Dec. 8, 1668, on the regency of Sweden, the more clearly I discover that the most important affairs are not regulated agreeable to the public interest, but according to that of the principal Ministers; and the surest and easiest way to succeed, is to gain him who has the King's ear rather than the King himself; because what is done for the good of the nation obliges no one in particular, and procures glory, but no acknowledgments. When I passed through Denmark, I perceived that more might be done by means of M.G. with a hundred thousand crowns, than can be done with the King with five times that sum."
