Introduction to the history of the principal kingdoms and states of Europe

Samuel Pufendorf was a pivotal figure in the early German Enlightenment and, along with Grotius, the great renewer of natural law theory.

His version of voluntarist natural law theory had a major influence both on the European continent and in the English speaking world, particularly Scotland and America. "An Introduction to the History of the Principal Kingdoms & States of Europe" was first translated in 1695 but has been rare in English since the late eighteenth century.

Pufendorf's histories exhibit the core notions of his natural law theory by recounting the development and current, reciprocal relations of individual states as collective social agents engaged in securing their own and, thus, their members' interests, including self-preservation.

Hence, his histories essentially functioned as vehicles for philosophical demonstration or justification.

Moreover, by emphasising empirical details and legitimating (in principle) the de facto politics of interest, these histories appealed strongly to the emerging nation-states of early modern Europe, which sought ratification of their external and internal actions, policies, and pedagogues.

He based his account on the respective country's own historians and took care to describe its position from its own current and historical perspectives.

It was a novel and appealing approach to political history, judging from the long and diverse publishing record of the work.
