Year 967 (CMLXVII) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. Events By place Europe Spring – Emperor Otto I (the Great) calls for a council at Rome, to present the new government under Pope John XIII. He asserts his rights in the city, and insists on the occasional presence of an imperial judge, alongside the papal court. The era of Roman independence is over.

Arabian Empire Emir Nasir al-Dawla is deposed and imprisoned at Mosul after a 32-year reign by his son Abu Taghlib, the de facto governor, and supporters.
