Year 180 BC was a year of the pre-Julian Roman calendar. At the time it was known as the Year of the Consulship of Luscus and Piso/Flaccus (or, less frequently, year 574 Ab urbe condita). The denomination 180 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.


By place[edit]


  • After three years of intriguing against his younger brother Demetrius, including accusing him of coveting the succession to the Macedonian throne and being allied to Rome, Perseus persuades his father King Philip V of Macedon to have Demetrius executed.

Roman Republic[edit]

  • Rome completes its subjugation of all of Italy with the defeat of the Ligurians in a battle near modern Genoa. Rome deports 40,000 Ligurians to other areas of the Republic.
  • Lucca becomes a Roman colony.




  • September 26Lü Clan Disturbance. Following the death of Empress Lü, who had been the de facto ruler of the Han Dynasty, the Lü Clan is overthrown and massacred by the imperial princes Liu Zhang and Liu Xiang, General-in-Chief Zhou Bo and Prime Minister Chen Ping.
  • Fearing reprisals should the young Emperor Houshao and his brothers reach adulthood, the conspirators deny that Emperor Hui was the father of Houshao and his brothers. They overthrow the emperor, and despite the imperial pedigree of Liu Xiang as the son of the eldest son of Gaozu of Han, they eventually agree to elevate Gaozu's oldest surviving son, Emperor Wen, to the throne. After being evicted from the palace, Houshao is executed later in the year.
  • Emperor Wen honours the relatives and ancestors of Zhao Tuo, the Chinese-born ruler of Nanyue (in present-day Vietnam and southern China). As a result, Nanyue returns to the Han dynasty as a vassal, although Zhao Tuo continues to call himself an emperor within his own kingdom.
