Ansei

From Wikipedia, the free encyclopedia

Ansei (安政) was a Japanese era after Kaei and before Man'en and spanned from November 27 (?), 1854 to March 18 (?), 1860. The reigning emperor was Komei.

[edit] Change of era

Due to the disasters of a fire at the Imperial Palace, earthquakes, and the arrival of the Black Ships (Commodore Matthew Perry's ships), the era was changed to Ansei (roughly "Quiet/peaceful Government")

[edit] Source of Name

From a quote "庶民安政、然後君子安位矣" ("Peaceful rule of the masses, peaceful succession"??)
