My question or rather discussion as it pertains to history is: Discuss the achievements of Japan's Heian and Kamakura periods. Look at political, military,economic and cultural spheres. Which period, in your opinion, was more significant to the future of Japan--and why (provide evidence).If possible provide footnotes and bibliography. I need at least two scholarly resources. Thank you.
