The period 1517-1625 was crucial for the development of political thought. During this time of expanding empires, religious upheaval, and social change, new ideas about the organisation and purpose of human communities began to be debated. In particular, there was a concern to understand the political or civil community as bounded, limited in geographical terms and with its own particular structures, characteristics and history. There was also a growing focus, in

the wake of the Reformation, on civil or political authority as distinct from the church or religious authority. The concept of sovereignty began to be used, alongside a new language of reason of state-in response, political theories based upon religion gained traction, especially arguments for the divine right of kings.
