List of Xi Dynasty Emperors

The Emperors of the Xi Dynasty were the supreme heads of government during the first Imperial Dynasty of Longzhou; the Xi Dynasty (268 BCE – 35 CE), preceding the later Imperial Dynasties.

The Xi Dynasty was founded by Long Dawei, known posthumously as Emperor Wei (r. 268-197 BC) or Longwei. The longest reigning emperor of the dynasty was Emperor Wei (r. 268-197 BC) or Longwei, who reigned for 731 years. The last Xi emperor, Emperor Xia (r. 27 BC-35 AD), was died in battle, leaving the court in Chaos, while the Xi remnants retreated back to the Xi Kingdom homelands. The emperor was the supreme head of government. He appointed all of the highest-ranking officials in central, provincial, commandery, and county administrations. He also functioned as a lawgiver, the highest court judge, and commander-in-chief of the armed forces.

Emperor
With the first unification of tribes under the Di Dynasty, a new title was sought, hence the title "Emperor" (Mandarin: 帝 Dì). When the Baiwang Dynasty reunited the tribes, they instead began using "皇" (Mandarin: huáng) which also meant "Emperor. The Later Long Dynaty were the first to connect both titles into one "Emperor" (Mandarin: 皇帝 Huángdì). The title of Emperor of Longzhou continues to be used in Longzhou.

Posthumous, temple, and era names
Once an emperor died, they would be given a posthumous name, usually their given name, but occasionally to a really good or bad emperor, an honorable or dishonorable name would be given. Era names were simply named after the Emperor who ruled that era.
