Mieszko I, a duke of the Piast Dynasty, becomes prince (de facto ruler) of Poland on the death of his father Siemomysł. Mieszko continues to subdue the neighbouring tribes under his control. Two obstacles to this plan are the Western Slav tribal group, the Veleti (also known as the Wilzi or "Wolf people") who are raiding Mieszko's lands for plunder; and the Saxon border dukes, who are pushing eastwards in search of new lands to conquer.[2]
Harald Bluetooth, king of Denmark, consolidates his rule over Jutland and Zealand. He adopts Christianity, erecting a carved stone at Jelling to honour his parents. It features a runic inscription (best-known in Denmark) and an image of Christ surrounded by interlace. The other Scandinavian kingdoms slowly convert to Christianity (approximate date).
Autumn – Oberto I, margrave of the Obertenghi family, takes refuge in Germany. He travels with influential Italian leaders to the Saxon court of Otto I to intervene in Italy to protect him from Berengar II.
February 4 – The Song Dynasty is established at Kaifeng by the 33-year-old military leader Zhao Kuangyin. He begins to unify the empire by conquering other lands and becomes the first emperor, called as Taizu of Song. The Song Dynasty will rule northern China for over 300 years (until 1279).
Summer – Otto I leads an expeditionary force into northern Italy through the Brenner Pass at Trento, to assist the beleaguered young Pope John XII. He proceeds towards Pavia – King Berengar II sends his son and co-ruler Adalbert II from Rome at the head of a large army to seize control of the Upper Adige and contest Otto's entry.
The Lombard army under Adalbert II refuses to fight Otto I unless Berengar II abdicates in favor of Adalbert. Berengar refuses, and the armies retreat to their strongholds. Berengar and his family take whatever loyal soldiers remain and disperse themselves – Berengar retreats to the fortress at Montefeltro (in the Pentapolis).
Armenia
King Ashot III of Armenia (the Merciful) moves his capital from Kars eastward to Ani (modern Turkey). Located on a major east-west caravan route, Ani will become larger than any European city, with a population of about 100,000 that will rival Baghdad, Cairo, and Constantinople. Ani also becomes the site of the royal mausoleum of the Bagratuni kings.[4]
December – Arab–Byzantine wars – Sack of Aleppo: A Byzantine expeditionary force under General Nikephoros Phokas invades northern Syria, and sacks Aleppo, capital of the Hamdanid emir Sayf al-Dawla. In late December Aleppo is taken by storm, with the population killed or enslaved; the city is razed. The Byzantine army takes possession of 390,000 silver dinars, 2,000 camels and 1,400 mules.
Otto I proceeds to lay siege to Lake Garda, where the sons of Berengar II, Guy of Ivrea and Adalbert II (co-ruler of Italy), and their supporters are holed up. Finding severe resistance, Otto gives up the enterprise and returns to Pavia, the capital of Lombardy.
Fall – Otto I receives news that John XII has betrayed him and entered into intrigues with Berengar II, but also with the Byzantine Empire. The letters are intercepted by Pandulf I (Ironhead), Lombard prince of Benevento.

The Nanping State, one of the Ten Kingdoms in south-central China, is forced to surrender, when invaded by armies of the Song Dynasty.
December 6 – Pope Leo VIII is appointed to the office of Protonotary and begins his papacy as antipope of Rome – a reign with the concurrently deposed John XII.
October 24–25 – Siege of Rometta: Nikephoros II sends an expedition to Sicily. The Byzantine army (40,000 men) is sent to break the Muslim siege at Rometta, and to regain Sicily for the Byzantine Empire. For two days a battle takes place in the area between the beach and the besieged citadel of Rometta. The Saracens (under Al-Hasan ibn Ammar) manage to defeat the Byzantine relief force.

Otto I dispatches an imperial delegation (led by a Venetian named Domenico) to Constantinople with assurances of his friendship and a request for Princess Theophano (a daughter of the late Emperor Romanos II) for his 12-year-old son Otto II.

The imperial delegation arrives in Macedonia, but goes nowhere with Nikephoros II. Far from offering Byzantine Italy as dowry for Theophano, Nikephoros refuses to accept the claims of Otto I.

Religion
Otto I completes and dedicates a new cathedral at Magdeburg in Saxony. Like other imperial churches of the period, it includes a westwork – a structure attached to the entrance wall and outfitted with galleries. Otto makes Magdeburg a base for missionary efforts to convert the Slavs to the east. The patron saint of the city is Mauritius, who, as a military leader fighting for Christianity against pagan armies, shares affinities with Otto himself.
Emperor Nikephoros II receives a Bulgarian embassy led by Prince Boris (the son of Tsar Peter I of Bulgaria), with a plea for help against the invading Kievan Rus'. Nikephoros, occupied in the East, is unable to support him. Instead he sends envoys to summon the Pechenegs to aid Boris. They besiege Kiev, but Grand Prince Sviatoslav I (on campaign in Bulgaria) returns with a Kievan relief force, and defeats the Pechenegs. He drives them out into the Steppe, and sets up viceroys to rule his Rus' territory.[22]
Europe
Spring – Emperor Otto I (the Great) travels to Capua to meet there with ambassadors of Nikephoros II, who again reiterate their friendship, but refuse to consent to his dowry demands (see 967). Otto invades the Byzantine Theme of Langobardia with a Lombard expeditionary force. With the assistance of Benevento-Capua and naval support from Pisa, Otto attempts to take Bari by assault, but Byzantine resistance is stiff, and Otto withdraws back to Ravenna.
Battle of Silistra: A Kievan army (60,000 men) led by Sviatoslav I crosses the Lower Danube and defeats the Bulgarians at Silistra. He occupies most of the Dobruja by seizing 80 fortresses in northeastern Bulgaria. They are looted and destroyed but not permanently occupied. During the winter, Sviatoslav transfers the capital from Kiev to Pereyaslavets.
Pandulf I (Ironhead), a Lombard prince, takes over the territory of Benevento and Capua after the death of his brother Landulf III. He appoints his son Landulf IV as co-prince of Benevento, and disinherits Pandulf II (a son of Landulf III) as lord of Sant'Agata (located northeast of Naples).
Peter I, emperor (tsar) of the Bulgarian Empire, suffers a stroke and abdicates the throne in favour of his eldest son Boris II. He arrives (after being an honorary hostage at Constantinople) in Preslav and is proclaimed as the new ruler. Boris regains lost territory from the Kievan Rus' and recaptures Pereyaslavets, an important trade city at the mouth of the Danube.[25]
Summer – Grand Prince Sviatoslav I invades Bulgaria at the head of a Kievan army, which includes Pecheneg and Hungarian auxiliary forces. He defeats the Bulgarians in a major battle and retakes Pereyaslavets. Boris II capitulates and impales 300 Bulgarian boyars for disloyalty. Sviatoslav assigns garrisons to the conquered fortresses in Northern Bulgaria.[26]
Pandulf Ironhead, duke of Benevento and Capua, leads the siege of Bovino. He is captured by the Byzantines and taken in chains to Bari, and jailed in Constantinople. Neapolitan forces under Marinus II, duke of Naples, invade Benevento-Capua, capture the city of Avellino and then lay siege to Capua.[27]
Otto I 'the Great', Holy Roman Emperor, assembles a large expeditionary force at Pavia, joined by Spoletan troops. He counter-attacks, relieves the siege of Capua and devastates the area around Naples. Otto enters Benevento, where he is received as 'liberator' by Landulf IV and in the cities of Apulia (Southern Italy).
