Year 643 (DCXLIII) was a common year starting on Wednesday (link will display the full calendar) of the Julian calendar. The denomination 643 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.

Byzantine Empire[edit]






  • Chinese prefectural government officials travel to the capital of Chang'an to give the annual report of the affairs in their districts. Emperor Taizong discovers that many have no proper quarters to rest in, and are renting rooms with merchants. Therefore, Taizong orders the government agencies in charge of municipal construction to build every visiting official his own private mansion in the capital.
  • A Chinese embassy is sent to the North Indian Empire. They are invited by emperor Harsha who holds a Buddhist convocation at the capital Kannauj which is attended by 20 kings and thousands of pilgrims.[1]
  • Taizong commissions artist Yan Liben to paint in the Lingyan Pavilion the life-size portraits of 24 government officials to commemorate their service and contributions to the founding of the Tang Dynasty.
