Problem: Geographically, the empire was divided into several provinces, the borders of which changed numerous times during the Umayyad reign. Each province had a governor appointed by the khalifah. The governor was in charge of the religious officials, army leaders, police, and civil administrators in his province. Local expenses were paid for by taxes coming from that province, with the remainder each year being sent to the central government in Damascus. As the central power of the Umayyad rulers waned in the later years of the dynasty, some governors neglected to send the extra tax revenue to Damascus and created great personal fortunes.

Problem: The Heian period was preceded by the Nara period and began in 794 A.D after the movement of the capital of Japan to Heian-kyo (present day Kyoto), by the 50th emperor, Emperor Kanmu. Kanmu first tried to move the capital to Nagaoka-kyo, but a series of disasters befell the city, prompting the emperor to relocate the capital a second time, to Heian. The Heian Period is considered a high point in Japanese culture that later generations have always admired. The period is also noted for the rise of the samurai class, which would eventually take power and start the feudal period of Japan.
