Århus, a seaport in eastern Jutland, Denmark, in 948 becomes a bishopric.

Otto I establishes the Bishopric of Brandenburg in 948.

A missionary diocese and a suffragan to the Archbishopric of Mainz, it includes the territory between the Elbe on the west, the Oder on the east, and the Schwarze Elster on the south, and taking in the Uckermark to the north.

Its seat is Brandenburg upon Havel.

The Hamdanids, after scoring initial victories against the invaders, are occupied with blocking incursions by imperial forces in the north, and are thus compelled to cede central and southern Syria to the Ikhshidites in 948.

A peace treaty is negotiated between Sayf ad-Dawlah and the Ikhshidids.

Hereafter Sayf's, most important concern will be with the Eastern Roman Empire.

Mu'izz al-Dawla has spent the past two years securing his control over Iraq.

The Hamdanid emir of Mosul and former amir al-umara, Nasir al-Dawla, had attempted to seize Baghdad in 946.

When they failed to do so, they gave up on the campaign, but have remained hostile against the Buyids.

The Baridis, who still control Basra and Wasit, had been defeated and their lands taken by the Buyids in 947.

Their defeat marks the end of major fighting.

Mu'izz al-Dawla's only failure is against an amirate situated in the marshlands between Basra and Wasit; this is of little concern, due to the amirate's small size.

Archaeological evidence suggests that Nri hegemony in Igboland may go back as far as the ninth century, and royal burials have been unearthed dating to at least the tenth century.

Eri, the god-like founder of Nri, is believed to have settled the region around 948.

Igbo-Ukwu is notable for three archaeological sites, where excavations have found bronze artifacts from a highly sophisticated bronze metalworking culture dating perhaps to the ninth or tenth century, centuries before other known bronzes of the region.

Alice Apley writes about the work: "The inhabitants of Igbo-Ukwu had a metalworking art that flourished as early as the ninth century.

Three sites have been excavated, revealing hundreds of ritual vessels and regalia castings of bronze or leaded bronze that are among the most inventive and technically accomplished bronzes ever made.

The people of Igbo-Ukwu, ancestors of present-day Igbo, were the earliest smithers of copper and its alloys in West Africa, working the metal through hammering, bending, twisting, and incising.

They are likely among the earliest groups of West Africans to employ the lost-wax casting techniques in the production of bronze sculptures.

Oddly, evidence suggests that their metalworking repertory was limited and Igbo smiths were not familiar with techniques such as raising, soldering, riveting, and wire making, though these techniques were used elsewhere on the continent."

Sayf al-Dawla captures Ramla from the Ikshidids, but is unable to make further progress.

The defeat at Slane appears to have lost Amlaíb his kingship, as the annals record that Blácaire not Amlaíb is the leader of the Dublin forces in the following year.

Blácaire is killed in 948 by Congalach, and is succeeded by Amlaíb's brother Gofraid.

St. Albans School, founded in 948 by Wulsin (Abbot Ulsinus) within St. Albans Abbey is not only the oldest school in Hertfordshire but also one of the oldest in the world.

St. Albans, being the first school open to the wider public, is the first school in the world to accept students not intending to join a religious order.

This has led to the school being called "Britain's oldest public school".

The Joshua Roll, an illuminated manuscript of highly unusual format, probably of the tenth century-Macedonian Renaissance, is believed to have been created by artists of the Imperial workshops in Constantinople; it is now in the Vatican Library.

The Roll is in the form of a continuous horizontal scroll or rotulus, common in Chinese art, but all but unique in surviving examples of medieval Christian art.

It is made of several joined pieces of sheep vellum, is thirty-one centimeters high and about ten meters long, and may be incomplete, as it starts with Chapter II and ends with Chapter X.

The Roll covers the early part of the Old Testament Book of Joshua using a reduced version of the Septuagint text; it includes Joshua's main military successes, ending with conquered kings paying him homage.

At roughly this time, the Empire is enjoying military success in its campaigns in the Holy Land.

It is originally painted in grisaille, by several artists, with partial coloring added later in a separate stage.

The lettering is in majuscule and minuscule forms.

Sayf al-Dawla raids into the imperial theme of Lykandos in 949, but is defeated.

The imperial army counterattacks and seizes Germanikeia, defeating an army from Tarsus, then …
