Events

March 15 – Emperor Romanos II dies at age 39, probably of poison administered by his wife, Empress Theophano. He is succeeded by his infant son Basil II. Theophano becomes regent and de facto ruler, naming her other son Constantine VIII (only 3 years old) as co-emperor of the Byzantine Empire.^[1]
July 2 – Nikephoros II Phokas is proclaimed emperor by his troops in Caesarea. He sends a fleet to secure the Bosphorus Strait against his enemies. Chief minister Joseph Bringas gathers support and closes the gates of Constantinople. General Marianos Argyros is killed in a riot, forcing Bringas to flee.
August 16 – Nikephoros II makes a triumphal entry in Constantinople and is hailed as 'the conqueror'. He is crowned emperor in Hagia Sophia.
September 20 – Nikephoros II marries the former Byzantine consort Theophano, the widow of Emperor Romanos II, bolstering his legitimacy.^[2]

Gero I, margrave of Merseburg, campaigns against the Slavs. He forces Prince Mieszko I of the Polans in Poland to pay tribute to Emperor Otto I ( the Great). He expands his territory, the Marca Geronis (March of Gero), to the mouth of the Oder River.^[3]
Sviatoslav I, Grand Prince of Kyiv, begins a 2-year campaign in which he will defeat Khazar forces along the Don River – vanquish the Ossetes and the Circassians in the northern Caucasus. He also successfully attacks the Bulgars on the Volga River.
November – Otto arrives at Rome; Pope John XII and Adalbert II (co-ruler of Italy) flee to Campania, taking with them most of the Papal treasury. The Roman citizens warmly receive Otto as a 'liberator'.
December – King Berengar II (the father of Adalbert II) surrenders at the fortress of Montefeltro to German forces. He and his wife Willa are taken prisoner and dispatched to Bamberg.
Luxembourg has her beginnings at Luxembourg Castle (located on the Bock), founded by Sigfried, count of the Ardennes.

The Chinese government of the Song Dynasty attempted to ban the practice of cremation; despite this decree, the lower and middle classes continued to cremate their dead until the government resolved the problem in the 12th century, establishing public graveyards for paupers.
The Nanping State, one of the Ten Kingdoms in south-central China, is forced to surrender, when invaded by armies of the Song Dynasty.
