Unit 3 – The Postclassical Era: Networks of Exchange and Expansion (c. 600 CE – 1450 CE)

2. How did religion, art, and ideas spread across regions?
3. How did cross-cultural interactions shape political, social, and economic systems?
4. What new technologies, beliefs, and institutions emerged from these exchanges?
