具瑗 / Ju Yuan (late Han eunuch)

Overview

具瑗 / Ju Yuan is a Huan-era eunuch whose current wiki role is source-bounded to the 159 CE overthrow of 梁冀. Hanji 848 presents him as one of 汉桓帝’s inner conspirators: he first arrests Liang’s palace monitor, then helps carry the armed operation against Liang’s mansion, and is later rewarded as one of the 桓帝五侯.

Current Profile

Hanji 848 makes Ju Yuan important because his actions occur at the point where palace proximity turns into command execution. Liang Ji sends Zhang Yun into the palace to watch 单超 and the other suspected eunuchs, but Ju Yuan arrests him for entering from outside and plotting improperly. The arrest clears Liang’s palace eye before Huan publicly convenes the shangshu channel and moves against Liang.

The same episode then places Ju Yuan in the armed phase. Huan orders him to lead more than one thousand left-right riders, Huben, Yulin guards, and armed specialists together with Sili xiaowei Zhang Biao to surround Liang’s mansion. After Liang and 孙寿 die, Ju Yuan is named in the five-member county-marquis reward group with Shan Chao, 徐璜, 左悺, and 唐衡.

Key Characteristics

• Palace-proximity actor whose first durable role is arresting Liang Ji’s monitor inside the palace.
• Coup executor who links inner-palace access control to armed pressure outside Liang’s mansion.
• Named founding member of the Huan-era Five Marquises.
• Source-bounded eunuch figure whose current profile is about function in the 159 CE coup rather than a full biography.

Evidence

• Monitor arrest: Hanji 848 says Liang Ji sends Zhang Yun into the palace to watch the eunuchs and that Ju Yuan arrests him on entry.
• Armed operation: Hanji 848 says Huan orders Ju Yuan to lead palace guards and armed personnel with Zhang Biao to surround Liang’s mansion.
• Reward status: Hanji 848 names Ju Yuan among the five eunuchs enfeoffed as county marquises after Liang’s fall.
• Group identity: Hanji 848 says the five were known in their time as the Five Marquises.

Qualifications

This page is not a full biography of Ju Yuan. It records only the Hanji 848 coup-and-reward role. The transcript form 巨爱 is normalized to 具瑗 because the office sequence, eunuch role, and Five Marquises membership match the received late-Han route, but the source note still keeps that normalization visible.

What Changed

• Created the page from Hanji 848’s palace arrest, armed-coup execution, and Five Marquises reward evidence.
