Jōkyū
Japanese era from April 1219 to April 1222

Jōkyū (承久), also called Shōkyū, was a Japanese era name (年号, nengō; lit. "year name") after Kempō and before Jōō. This period spanned the years from April 1219 through April 1222. The reigning emperor was Juntoku-tennō (順徳天皇).
Change of era
1219 Jōkyū gannen (承久元年): The new era name was created because the previous era ended and a new one commenced in Kempo 3, on the 6th day of the 12th month of 1219.
Events of the Jōkyū era
February 12, 1219 (Jōkyū 1, 26th day of the 1st month): Shōgun Sanetomo was assassinated on the steps of Tsurugaoka Hachiman-gū in Kamakura. The 40 years during which Minamoto no Yoritomo, Minamoto no Yoriie and Minamoto no Sanetomo were successive heads of the Kamakura shogunate was sometimes called "the period of the three shōguns." A new shōgun was not to be named for several years during which the Kamakura bureaucracy nevertheless continued to function without interruption.
1220 (Jōkyū 2, 2nd month): The emperor visited the Iwashimizu Shrine and the Kamo Shrines.
May 13, 1221 (Jōkyū 3, 20th day of the 4th month): In the 11th year of Juntoku-tennō's reign (順徳天皇11年), the emperor abdicated; and the succession (senso) was received by eldest son who was only 4 years old. Shortly thereafter, Emperor Chūkyō is said to have acceded to the throne (sokui).

Why this record matters
A short description can identify a subject without explaining its stakes. For “Jōkyū”, the useful work is to connect “japanese era from April 1219 to April 1222” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 25, 2026. The linked authority identifier is Q1195428. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1219, 1222, 1220 and 1221.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
