By place

  • Summer – Shen Kuo, Chinese polymath scientist and statesman, solves a border dispute with the Liao Dynasty by dredging up old diplomatic records. He refutes Emperor Dao Zong's bluffs point for point during a meeting at Mt. Yongan (near modern-day Pingquan), reestablishing the rightful borders of the Song Dynasty.
  • Vietnamese forces under General Lý Thường Kiệt defend Vietnam against a Chinese invasion.
  • The Liao Dynasty version of the Buddhist Tripiṭaka is completed (approximate date).

By topic

  • February – Pope Gregory VII holds a council in the Lateran Palace at Rome. He publishes a decree against laymen investiture (an act which will later cause the Investiture Controversy).
  • April – Gregory VII publishes the Dictatus papae (a compilation of 27 statements of powers), in which he asserts papal authority over earthly as well as spiritual rulers.
  • December 8 – Gregory VII writes a letter of reprimand to Henry IV. He accuses him of breaching his word and continued support of excommunicated councilors.
