  Events of the ''Jōkyū'' era

• February 12, 1219 : 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 : The emperor visited the Iwashimizu Shrine and the Kamo Shrines.
• May 13, 1221 : In the 11th year of Juntoku-tennō 's reign, the emperor abdicated; and the succession was received by eldest son who was only 4 years old. Shortly thereafter, Emperor Chūkyō is said to have acceded to the throne. The reign of Emperor Chūkyō spans a small number of months.
• July 29, 1221 : In the 1st year of what is now considered to have been Chūkyō-tennō 's reign, he abruptly abdicated without designating an heir; and contemporary scholars then construed that the succession was received by a grandson of former Emperor Go-Toba.
• 1221 : The Jōkyū War was an armed attempt by Emperor Go-Toba and his supporters, trying unsuccessfully to take power from the Kamakura bakufu.
• January 14, 1222 : Emperor Go-Horikawa acceded to the throne.
