What was more likely to happen during the postclassical era than during the classical period?

During the postclassical era, there was a significant increase in long-distance trade and cultural exchange, particularly due to the establishment of trade networks like the Silk Road and maritime routes. This period also saw the rise of complex political entities, such as empires and city-states, which facilitated greater interaction among diverse cultures. Additionally, the spread of religions, such as Islam and Buddhism, was more pronounced during this time, influencing societies across vast regions.
