Geunchogo of BaekjeGeunchogo of Baekje, Chogo II of Baekje (324–375, r. 346–375) was the 13th king of Baekje, one of the Three Kingdoms of Korea. He reigned over the apex of Baekje's powers. Geunchogo was the fourth son of the 11th king Biryu and became king upon the death of the 12th king Gye. His reign seems to have marked the permanent ascendancy of the descendants of the 5th king Chogo (reflected in Geunchogo's name) over those of the 8th king Goi, and ended the alternating kingship of the two lines.
Soga clanThe Soga clan was one of the most powerful aristocratic kin groups (uji) of the Asuka period of the early Japanese state—the Yamato polity—and played a major role in the spread of Buddhism. Through the 5th and 7th centuries, the Soga monopolized the kabane or hereditary rank of Great Omi and was the first of many families to dominate the Imperial House of Japan by influencing the order of succession and government policy. The last Soga predates any historical work in Japan, and very little is known about its earliest members.
Nakatomi clanwas a Japanese aristocratic kin group (uji). The clan claims descent from Amenokoyane. The Nakatomi was an influential clan in Classical Japan. Along with the Inbe clan, the Nakatomi were one of the two clans that oversaw certain important national rites, and one of many to claim descent from divine clan ancestors "only a degree less sublime than the imperial ancestors". It is said that soon after the beginning of Jimmu's reign, a Master of Ceremonies (saishu) was appointed; and this office was commonly held by a member of the Nakatomi clan after the 8th century.
Nara periodThe Nara period of the history of Japan covers the years from CE 710 to 794. Empress Genmei established the capital of Heijō-kyō (present-day Nara). Except for a five-year period (740–745), when the capital was briefly moved again, it remained the capital of Japanese civilization until Emperor Kanmu established a new capital, Nagaoka-kyō, in 784, before moving to Heian-kyō, modern Kyoto, a decade later in 794. Japanese society during this period was predominantly agricultural and centered on village life.
Emperor Tenmuwas the 40th Emperor of Japan, according to the traditional order of succession. He reigned from 673 until his death in 686. Tenmu was the youngest son of Emperor Jomei and Empress Kōgyoku, and the younger brother of the Emperor Tenji. His name at birth was Prince Ōama (大海人皇子:Ōama no ōji). He was succeeded by Empress Jitō, who was both his niece and his wife. During the reign of his elder brother, Emperor Tenji, Tenmu was forced to marry several of Tenji's daughters because Tenji thought those marriages would help to strengthen political ties between the two brothers.
BaekjeBaekje or Paekche (, pɛk̚.t͈ɕe) was a Korean kingdom located in southwestern Korea from 18 BC to 660 AD. It was one of the Three Kingdoms of Korea, together with Goguryeo and Silla. While the three kingdoms were in separate existence, Baekje had the highest population of approximately 3,800,000 people (760,000 households), which was similar to that of Goguryeo (3,500,000 people) and much larger than that of Silla (850,000 people). Baekje was founded by Onjo, the third son of Goguryeo's founder Jumong and Soseono, at Wiryeseong (present-day southern Seoul).
Taika ReformThe Taika Reforms were a set of doctrines established by Emperor Kōtoku (孝徳天皇 Kōtoku tennō) in the year 645. They were written shortly after the death of Prince Shōtoku and the defeat of the Soga clan (蘇我氏 Soga no uji), uniting Japan. The reforms also artistically marked the end of the Asuka period and the beginning of the Hakuhō period. Crown Prince Naka no Ōe (the future Emperor Tenji), Nakatomi no Kamatari, and Emperor Kōtoku jointly embarked on the details of the Reforms.
Samguk SagiSamguk Sagi (, History of the Three Kingdoms) is a historical record of the Three Kingdoms of Korea: Goguryeo, Baekje and Silla. The Samguk Sagi is written in Classical Chinese, the written language of the literati of ancient Korea, and its compilation was ordered by King Injong of Goryeo (r. 1122-1146) and undertaken by the government official and historian Kim Busik () and a team of junior scholars. Completed in 1145, it is well known in Korea as the oldest surviving chronicle of Korean history.
Nihon ShokiThe Nihon Shoki, sometimes translated as The Chronicles of Japan, is the second-oldest book of classical Japanese history. The book is also called the Nihongi. It is more elaborate and detailed than the Kojiki, the oldest, and has proven to be an important tool for historians and archaeologists as it includes the most complete extant historical record of ancient Japan. The Nihon Shoki was finished in 720 under the editorial supervision of Prince Toneri with the assistance of Ō no Yasumaro and presented to Empress Genshō.
