The Renaissance (15th to 17th century) represented a cultural revival in Europe, emphasizing a humanistic worldview and the importance of individual glory over religious faith. Key figures like Machiavelli shaped modern political thought, advocating for a secular approach to governance and the use of historical examples to understand state behavior. The establishment of nation-states led to clearly defined boundaries, centralized governments, and a growing awareness of national identity, reflected in the works of thinkers such as Sir John Fortescue and Sir Thomas Smith.
