The Nara period (奈良時代?) of the 8th century marked the first emergence of a strong Japanese state. Following an Imperial rescript by Empress Genmei the move of the capital to Heijō-kyō, present-day Nara, took place in 710. The city was modelled on the capital of the Chinese Tang Dynasty, Chang"an (now Xi"an).
During the Nara Period, political development was quite limited, since members of the imperial family struggled for power with the Buddhist clergy as well as the regents, the Fujiwara clan. Japan did enjoy friendly relations with Silla as well as formal relationships with Tang China. In 784, the capital was moved again to Nagaoka to escape the Buddhist priests and then in 794 to Heian-kyo, present-day Kyoto.
Historical writing in Japan culminated in the early 8th century with the massive chronicles, the Kojiki (The Record of Ancient Matters, 712) and the Nihon Shoki (Chronicles of Japan, 720). These chronicles give a legendary account of Japan"s beginnings, today known as the Japanese mythology. According to the myths contained in these 2 chronicles, Japan was founded in 660 BC by the ancestral Emperor Jimmu, a direct descendant of the Shinto deity Amaterasu, or the Sun Goddess. The myths recorded that Jimmu started a line of emperors that remains to this day. Historians assume the myths partly describe historical facts but the first emperor who actually existed was Emperor Ōjin, though the date of his reign is uncertain. After the Nara period, actual political power has not been in the hands of the emperor, but in the hands of the court nobility, the shoguns, the military and, more recently, the prime minister.
