depose him. This was in direct opposition to the ideas on the God-given absolute sovereignty of kings that were being proffered by Protestant theologians in the early sixteenth century, and by political thinkers like the French jurist Jean Bodin at the end of the century. Indeed, Jean Bodin's influential Six Books of the Republic was an important influence on Botero's writing of the Reason of State, even if, as with Machiavelli's Prince, much of that influence was negative. While Botero disagrees with Bodin's thought on sovereignty, preferring something more popularly based, he does agree with some of Bodin's economic ideas. Nonetheless, Botero's overall conception of political economy is again more 'liberal' than that of Bodin, who argued for active participation by kings in the economy of the country, including mercantilist policies that would be enacted wholeheartedly in early modern France by Louis XIV and Colbert. Bodin cautioned kings only against trading with their own subjects; all other economic activity was allowed. Botero, on the other hand, argued that there were only three cases where the prince could take part in trade: 1) if no private citizen could afford it, 2) if a single private citizen would grow too powerful by the profits of it, or 3) there were some shortfall in supply whereby the prince would have to aid in the distribution of goods. Ultimately, Botero argued that economic activity was unbecoming a prince, and that the people were to be the prime economic mover in the state. Later works, life, and influence Through the 1590s, Botero continued in the employ of Federico Borromeo, who would become Archbishop of Milan in 1595. Botero mixed in the high society of Rome and Milan in these years, and published another work for which he was to become quite well known, the Relazioni Universali. Released in four volumes between 1591 and 1598 (a fifth volume was finally published in the late nineteenth century), the 'relations' of the title referred to those of the 'universal' (Catholic) church in various parts of the world, a treatise on "The Strength of all the Powers of Europe and Asia", and even includes the Americas. The work marks the beginning of demographic studies. Finishing his employment with Federico Borromeo in 1599, Botero returned to the House of Savoy, to be tutor to three sons of Charles Emmanuel. He would tour Spain with his three charges from 1603 to
