How is the modern era different from the post classical era?

The modern era, beginning around the late 15th century, is characterized by significant advancements in science, technology, and political thought, leading to revolutions in industry and governance. In contrast, the post-classical era, spanning roughly from the 5th to the 15th centuries, was marked by the rise of empires, the spread of major world religions, and cultural exchanges along trade routes like the Silk Road. Additionally, the modern era saw the emergence of nation-states and increased globalization, whereas the post-classical era was more defined by localized societies and feudal systems. These shifts led to profound changes in social structures, economic practices, and human understanding of the world.
