1607, no doubt associating with the closest of Philip III's advisors, from whom his ideas would be passed on to Philip IV's most trusted policy-maker, the Count-Duke of Olivares. Here is where Botero's work began to have an influence. Olivares seems to have used Botero's Reason of State to outline the strategy for preserving the Spanish Empire in his famous Memorial on the Union of Arms. There is also evidence that Duke Maximilian of Bavaria, one of the staunchest political supporters of Catholic reform and a leading figure of the Thirty Years' War, had discussed the Reason of State with his advisors. Thus, Botero's thought was able to shape at least some of the policy among the European states of the very troubled seventeenth century. Botero's work would also influence the next generation of political and economic thinkers. Thomas Mun's liberal mercantilist treatise England's Treasure by Foreign Trade, written in 1624, but not published until 1664, owes something to the Reason of State, and there is evidence that the great Belgian thinker Justus Lipsius read the Reason of State. Botero died in Turin in 1617. See also Botero (surname). Italian surname Citations References Aquinas, St. Thomas, On Law, Morality, and Ethics. Edited, with an introduction by William J.
