Overview

Jingo-keiun (神護景雲) is the Japanese era name (nengō) that spanned the years from August 767 through October 770 in the late Nara period. Era names in Japan were used to mark periods of rule and were changed for a variety of reasons such as imperial accession, auspicious omens, disasters, or political decisions. The Jingo-keiun era followed Tenpyō-jingo and was succeeded by Hōki.

Key facts:

  • Era name: Jingo-keiun — part of the traditional nengō system
  • Dates: August 767 to October 770
  • Preceded by: Tenpyō-jingo
  • Succeeded by: Hōki
  • Reigning sovereign: Shōtoku-tennō (the former Empress Kōken)

Political and historical context

Jingo-keiun falls within the broader Nara period (710–794), an era noted for the consolidation of a centralized state, the growth of Buddhism as a political as well as religious force, and the development of court institutions. The woman who reigned during Jingo-keiun is commonly called Empress Shōtoku; she had earlier reigned under the name Empress Kōken and later resumed the throne, retaining significant influence over court affairs. Her second reign is often discussed for the prominence of influential courtiers and Buddhist clergy.

Notable developments and events

Although the Jingo-keiun era itself was brief, it belongs to a politically charged interval. In the years immediately preceding this era, conflicts among powerful courtiers and the rise of religious figures to political prominence shaped imperial politics. The influence of certain Buddhist priests at court and tensions with leading aristocratic families left a lasting impression on how later administrations regulated clerical intervention in government. The death of the reigning sovereign in 770 brought an end to this era name and led to succession arrangements that initiated the Hōki era.

Significance and legacy

Jingo-keiun is significant primarily as a short, transitional period that helps historians trace the sequence of reigns and political changes in the mid-8th century. It illustrates how era names functioned as markers for shifts in authority and how religious and courtly factions could affect governance. The period is also cited in studies of the Nara court's evolving relationship with Buddhism and the later reactions that limited clerical power in state affairs.
