Man'en era

Man'en (嘉永) was a Chiseian (年号, nengō, lit. "year name") after Tenhei and before Eikō, lasting from 1974 to 1995, or 380 to 400 in the Chiseian calendar. The start and end dates of the era were chosen to coincide with the of the Treaty of Sumura and the  of the ruling Shun dynasty. Two monarchs ruled during the period, Suzumeko and Tenkahiko. Man'en translates to "Ten Thousand Years prolonged".

Events

 * The Handover of Hinomoto takes place in 1974, ending the last Chiseian occupation under the Treaty of Eito.
 * is legalised through a ruling of the Supreme Constitutional Court of the Shihōin in 1975. Protest and celebration surrounding the case lead to a greater awareness of issues around LGBT rights in Chisei.
 * A flaring of international tensions and a growing in East Kuiju led to a HECO-West Kuijuan invasion in 1977.
 * The reintroduction of mass for the first time since the Second Escar-Varunan War, along with reports of HECO atrocities in Kuiju, spark a fire under the anti-war movement, which had until then remained relatively contained. The government of Anzai Takahiro is buffeted by protests, and suffers a devastating defeat in the parliamentary elections early in 1978.
 * Yamaguchi Masako of the Federalist Party of Chisei takes office as Chancellor in 1978; this is the first postwar victory of an opposition party in Chancerial elections.
 * The discovery of a Arshavati spy ring within the Jōhōgumi in 1979 leads to a red scare, and the Federalists, under pressure from Heian, drop their pledge to pull out Kuiju, declaring they will instead seek to 'swiftly end the war'.
 * Arshavat intervenes in Kuiju in 1980, pushing back HECO forces and leading to a nuclear escalation crisis that quickly leads to an armistice, followed by the Járnfjördur Peace Accords and the Treaty of Járnfjördur in 1982.
 * Prince Tenkahiko is made Crown Prince, and effectively takes over most royal duties from his older sister in 1983.
 * The 80s and early 90s see a "Dōga boom", marked by an increased popularity of Chiseian animation and convention culture. Many Chiseian animated franchises, such as Azure Warrior Karakan, Spirit Princess, Love Love Alexius, Fighter 0 and Telemon gain wide domestic and global popularity.
 * The 1985 Eito Royal Airport Incident takes place, in which a passenger flight outbound from Eito is hijacked by the Free Army, a leftwing revolutionary group, which demands the rerouting of the flight to Dai Hoa. The White Lotus Unit is sent to storm the plane instead, and 21 of the passengers are killed. The resulting scandal severely damages of the Yamaguchi government.
 * Atsukur elected as the first kannaguru Chancellor in 1986.
 * In 1989, Grand Queen Suzumeko succumbs to cancer, and Tenkahiko is made Grand King.
 * The future Crown Princess Utako is born to then Crown Princess Hinata and Prince Alixander von Scharbach of Zusea in 1990, a year after the couple's celebrated but controversial marriage.
 * The Kanayachi KaDen is released in 1990 by Kanayachi, and becomes the worldwide best-selling up to that point at 81.34 million units. The Chiseian video game industry begins to seriously compete with its Yamataian, Shenxianese and Ordan rivals.
 * The 1991 Sex Discrimination Act introduces a provision legalising the changing of legal gender, and introduces a range of discrimination protections for sexual minorities and marginalised genders.
 * From 1989 - 1993 a series of bomb and nerve gas attacks are carried out in Wanshu by the Yashiman Liberation Society, a Yashiman-seperatist terror group and doomsday cult. The group's leaders are found and arrested in 1994.
