Iwai Rebellion participant Mononobe no Arakabi
Rebellion
At the beginning of the 6th century, the rising Silla kingdom began to threaten Japanese possessions in Korea. In 512, four districts of the Japanese colony of Mimana surrendered to the Koreans, and the remaining Japanese possessions came under siege. At the same time, the kingdom of Paekje, a Japanese vassal, was attacked from two sides by the kingdoms of Silla and Goguryeo, and sent 513 Confucian scholars to Yamato with a request for help - they brought with them the first books, and thus literacy came to Japan. Before Yamato could send aid to Mimana and Paekje, Iwai, the governor of the Tsukushi region (semi-autonomous Kumaso region in northern Kyushu), made a treacherous alliance with the Silla kingdom, thus blocking the Yamato kingdom's attempts to send aid to Korea. This was the first recorded rebellion against the ruling Yamato dynasty. Mononobe no Arakabi, the leader of a warrior clan, was sent to quell the rebellion. In 528, Iwai was overthrown and executed, and the previous autonomy of his area ended with the establishment of Daizafu Fortress, a government military stronghold on the island of Kyushu.
