Empress Gacudai, commonly known as Empress Aico outside of Japan, was the 127th occupant of the Chrysanthemum Throne. She took power on Gacudai Gannen, Gogaçu 1 (June 5, 2004), innaugurating the Gacudai era. Gacudai is her posthumous name, but during life, she was known simply as Her Majesty the Emperor*. Her titles were: Emperor of Japan, Queen of Corea, Queen of Yamato, Over-Queen of Lùquiù, High Queen of the Micronesian Confederation, Protector of Nittatò, Proprietor of Meidji-dò, President of the East Asian Federation, First Citizen of Ezo, Defender of her Peoples, and Defender of the Faiths.
She was born as Aico, Princess Toxi (敬宮愛子内親王), the firstborn daughter of the slain Prince Hiro, firstborn son of Emperor Saisei. She ascended the throne upon the abdication of her grandfather on Saisei 54/Gacudai Gannen, Gogaçu 1 (June 6, 2004). She is the first woman to sit on the Imperial throne since Gosacuramatxi, who reigned AD 1763-1770, who had abdicated to her nephew when he came of age, and the first with actual power since the Còquen-Xòtocu Emperess of AD 749-758 and 764-770 (she was deposed in 758 and returned to power in 764). The name of her reign, Gacudai (Haktai in Corean), translates as "Age of Learning", and in her ascension speech, she declared a desire to encourage the sciences in the Empire. Her formal coronation was held Gacudai 2, Gogaçu 1 (June 6, 2005). She married Masahito, Prince Alisugawa on the same day.
According to Xintò, she was a living goddess, and descendeant of Amaterasu Òmicami, goddess of the sun. According to Zesucutò, she was a living seidjin (holy person/saint), and descendant of King David of Israel (Isuraeru no Dabido Ò).
*The term Emperor is the standard translation of the Japanese tennò, regardless of the gender of the person who holds the title. The term empress is reserved to wives of the Emperor who have been specially given the title. The Western press initially, for the most part, followed the Japanese usage. However, after the first couple of years, a number of newspapers have quietly switched to Empress.
Her Majesty received her college education in the Imperial University System at Quiòto Imperial University prior to her ascent to the throne.
On Gacudai 3, Itxigaçu 14 (February 18, 2006), it was announced that she was pregnant with twin boys. On Xigaçu 18 (May 25), she gave birth to the future Emperor Xigehito and Prince Nolihito.
Assassination
On August 28, 2006, Empress Aico was assassinated by unknown hands in Lyons-sur-Mizouri. The investigation is ongoing. It was originally believed that the perpetrators were either the Yacuza, or Corean separatists, however, in the intervening years, it has seemed more likely that blame lies with the People's Party of Japan or Lousiannian Pegre figures.
