The account of Shō Nei, whose reign saw invasion and subjugation by Satsuma, opens with the statement that the kingdom had been in subordinate vassal status to the Shimazu clan since the Eikyō era. The account of the siring of Shunten by Minamoto no Tametomo was similarly exploited during the Meiji period and after to help legitimize the annexation of the kingdom and its reconfiguration first as the Ryūkyū Domain and subsequently as Okinawa Prefecture.
