Late Renaissance conflicts drew mercenaries of knowledge to act as informal mediators in a wide range of diplomatic interests and territories located around the Holy See. Since the sixteenth century, Rome had become a refuge for foreign subjects, many of whom Romanized themselves while securing their patrimonies across and beyond the city. Nogueira offered his services from Rome to patrons and correspondents in Paris and Lisbon as well as in the Eternal City. This chapter discusses the multivalent position he occupied as a bibliopolitician in Rome after his return from Bologna in 1640 and the beginnings of his involvement with the politics of the Portuguese Restoration.

Chapter 8 details the on-going importance of the politics of alliance before and after the 1648 Peace of Westphalia. In the Empire, the organization of alliances shifted in the second half of the seventeenth century, as the principles of corporate alliance migrated into princely military leagues like the 1658 Rhenish Alliance and large-scale associations among Imperial Circles. Despite their different structures, both the military alliances and Circle Associations adopted the rhetoric of earlier leagues and mirrored their goals. Related processes played out in the United Provinces, where the decades after Westphalia witnessed a running debate over what form the Dutch state should take. At the heart of this conflict sat competing ideas about the Union of Utrecht. The Union served as a focal point for all kinds of proposals about the Dutch Republic’s operation. One of the few things that each side agreed on was the Union’s centrality. Accordingly, the development of the Dutch state during this period was inseparable from struggles over the Union’s meaning. By examining Westphalia’s legacy in both the Empire and United Provinces, this chapter traces the lasting influence of the politics of alliance on northern Europe’s political systems into the late seventeenth century and beyond.
