Henry V of Brunswick vs King Jungjong of Joseon

Henry V inherited the Duchy of Brunswick-Wolfenb

Henry V participated in the Hildesheim Diocesan Feud, fighting against the Bishop of Hildesheim. The conflict ended with the Treaty of Quedlinburg, which reduced the bishop's territory and strengthened the position of the Brunswick dukes.

Henry V was a staunch Catholic and actively opposed the Protestant Reformation in his territories. He expelled Lutheran preachers, enforced Catholic worship, and allied with Emperor Charles V against the Schmalkaldic League.

Henry V was defeated and captured by the forces of the Schmalkaldic League, led by John Frederick I of Saxony and Philip of Hesse. He was imprisoned for several years, and his duchy was occupied by Protestant forces, which introduced the Reformation there.

After the Imperial victory at M

Henry V was forced to accept the Treaty of Passau, which granted religious toleration to Lutherans. This treaty ended his ability to suppress Protestantism in his territories and marked a setback for Catholic forces in the Empire.

Jungjong was installed as king of Joseon after the deposition of his half-brother Yeonsangun. His reign began with promises of reform, but he soon faced factional struggles between the officials who had placed him on the throne.

Jungjong promoted the Hyangyak system, a set of Confucian community compacts that encouraged local self-governance and moral education. This reform aimed to strengthen social order at the village level but had limited success due to factional opposition.

Jungjong ordered a purge of the Sarim faction, executing or exiling many reform-minded officials. This event, known as the Gimyo Literati Purge, reversed earlier reforms and deepened factional divisions in the court.

Jungjong attempted to revive the Royal Lecture (Gyeongyeon) system, where the king studied Confucian texts with scholars. The effort was undermined by factional infighting and never fully restored, limiting intellectual exchange at court.
