Glycerius vs Queen Seondeok of Silla

Glycerius was proclaimed Western Roman Emperor at Ravenna by the magister militum Gundobad, succeeding Olybrius. His elevation was not recognized by the Eastern Roman Emperor Leo I, who considered him a usurper.

The Eastern Roman Emperor Leo I sent Julius Nepos with a fleet to Italy to depose Glycerius. Nepos landed near Rome, and Glycerius was forced to abdicate without significant resistance. He was then appointed Bishop of Salona in Dalmatia.

Seondeok ascended the throne as the first reigning queen of Silla, following her father King Jinpyeong's death without a male heir. Her accession challenged traditional gender norms and established a precedent for female leadership in Korean history.

Queen Seondeok ordered the construction of Cheomseongdae, an astronomical observatory in Gyeongju. The stone structure was used for observing stars and predicting celestial events, reflecting Silla's advanced scientific knowledge and the queen's interest in astronomy.

Seondeok sent envoys to the Tang court, establishing a formal alliance. This diplomatic move secured Chinese support against Silla's rivals, Baekje and Goguryeo, and laid the groundwork for the later Silla-Tang alliance that unified Korea.

Seondeok sponsored the construction of several Buddhist temples, including Bunhwangsa and Yeongmyosa. She also supported the creation of Buddhist art and scriptures, contributing to the flourishing of Buddhist culture in Silla during her reign.

Seondeok faced a rebellion led by General Bidam, who opposed female rule. The queen's forces, led by General Kim Yushin, crushed the revolt. This victory solidified her authority and demonstrated the effectiveness of the Hwarang military system.
