Man'en

Man'en was a Japanese era name after Ansei and before Bunkyū. This period spanned the years from March 1860 through February 1861. The reigning emperor was Emperor Kōmei.

Change of era

March 18, 1860 : The new era name was created to mark the destruction caused by a fire at Edo Castle and the assassination of Ii Naosuke. The previous era ended and a new one commenced in Ansei 7.
The new era name is derived from an hortatory aphorism to be found in The Book of the Later Han: "With 100,000,000,000 descendants, your name will forever be recorded".
