Prince Rostislav of Moravia, who had succeeded…

The dispossessed Rorik of Dorestad may be identical with the semilegendary Rurik, leader of a group of fellow Rus', or Varangian (Swedish Viking) adventurers from Scandinavia, who between 860 and 862 takes control of Novgorod, either by raids or in answer to invitations by the Slavic populace.

He establishes a trading center near Lake Ladoga (Oneya).

Even though some historians emphasize folklore roots for the Rurik legend and consequently dismiss Rurik as a legendary figure, there is a controversy about his ethnic origins in Eastern Europe.

According to the Primary Chronicle, the earliest East Slavic chronicle, Rurik was one of the Rus', a Varangian tribe likened by the chronicler to Danes, Swedes, English and Gotlanders.

In the twentieth century, archaeologists partly corroborated the chronicle's version of events.

It was discovered that the settlement of Ladoga, whose foundation has been ascribed to Rurik, was actually established in the mid-ninth century.

Earthenware, household utensils, and types of buildings from the period of Rurik's foundation correspond to patterns then prevalent in Jutland.

According to the Primary Chronicle for the years 859-862, the Varangians were first expelled, then invited to rule the warring Slavic and Finnic tribes of Novgorod: The four tribes who had been forced to pay tribute to the Varangians—Chuds (proto-Estonians), Merians (proto-Volga Finns), Krivichs, and other Slavs—drove the Varangians back beyond the sea, refused to pay them further tribute, and set out to govern themselves.

But there was no law among them, and tribe rose against tribe.

Discord thus ensued among them, and they began to war one against the other.

They said to themselves, "Let us seek a prince who may rule over us, and judge us according to custom.

Thus they went overseas to the Varangians, to the Rus.

These particular Varangians were known as Rus, just as some are called Swedes, and others Normans and Angles, and still others Gotlanders, for they were thus named.

The Chuds, the Slavs, the Krivichs, and the Veps then said to the Rus, "Our land is great and rich, but there is no order in it.

Come reign as princes, rule over us".

Three brothers, with their kinfolk, were selected.

They brought with them all the Rus and migrated.

Smolensk, situated on the upper reaches of the Dnepr River near the present border between Russia and Belarus, is first mentioned by Russian historical chronicles in 862, as is …

…Murom, along the left bank of Oka River, about three hundred kilometers east of Moscow; it is the easternmost settlement of the Eastern Slavs in the land of Finno-Ugric people called muroma.

Al-Muntasir's reign lasts less than half a year; it ends with his death of unknown causes in 862.

He is the first 'Abbasid whose tomb is known; it is made by his mother, an enslaved Greek woman.

Earlier caliphs had desired the location of their tombs to be kept secret for fear of desecration.

Carloman of Bavaria revolts against his father Louis the German, king of East Francia, and tries to extend the territory under his control, but is defeated in 862.

The birth date of Carloman, whose mother is Emma, daughter of the count Welf, is unknown, but was probably around 830.

His naming can be connected to his father's push to rule Alemannia around the time of his father's assembly of Worms in 829.

The first Carolingian dynast named Carloman had ruled Alemannia in 741–48, and subjugated it to the Franks.

Carloman had been old enough to participate in the civil war of 840–43, waged between his father and his uncles, Lothair and Charles the Bald.

His first record public appearance is as the leader of an army of reinforcements from Bavaria and Alemannia which he brought to his father at Worms in 842.

He subsequently led them in battle alongside his father and uncle (Charles the Bald) against his other uncle (Lothair).

It was the beginning of a warlike career.

Notker of Saint Gall, who bewailed the decline of the dynasty a generation later, called Carloman bellicosissimus (literally "most warlike").

Carloman had been present at his father's council in Regensburg, where the Slavic commander (dux) Pribina had been rewarded for his service in defending the Bavarian frontier in October 848.

In the charter confirming the grant, Carloman had signed his name first among the secular magnates (after the ecclesiastics).

Carloman had had a liaison with Liutswind, daughter of the Bavarian count Ratolt and sister-in-law of Count Sigihard of the Kraichgau.

This was Carloman's first politically independent action, and it confirms his close connection to Bavaria.

Liutswind had borne him a son, Arnulf, around 850.

This name was chosen because it was distinctly dynastic (the founder of the Carolingian family was Bishop Arnulf of Metz), yet had never been used by a reigning king and was thus appropriate for an illegitimate eldest son.

The choice of the name is the surest evidence that Liutswind and Carloman were not legally married.

Louis had first associated Carloman with his rule by appointing him prefect to the march of Pannonia, the Bavarian borderland fronting Great Moravia and Pannonian Croatia, in 856. 

He did not give Carloman the traditional prefect's seat at Tulln in Pannonia.

Instead, according to the Annales Fuldenses (863), he was given the title "prefect of the Carantanians" (praelatus Carantanis) and posted further south, in a more peripheral region, perhaps in a design to keep him from trying to seize power from his father.

Carloman and his younger brother Louis have been occasional witnesses to their father's charters since 857.

Arnulf and his cousin, Hugh, Louis's illegitimate son, were both in Koblenz around 860 at the court of their grandfather, who was probably overseeing their military education and also holding them to ensure the good behavior of their fathers.

The Balearic Islands, now nominally both Eastern Roman and Umayyad and de facto independent, occupy a strategic and profitable gray area between the competing religions and kingdoms of the western Mediterranean.

The prosperous islands are thoroughly sacked by the Swedish Viking King Björn Ironside and his brother Hastein during their Mediterranean raid of 859-862.

Björn Ironside and his brother Hastein, powerful Viking chieftains and naval commanders, have conducted many (mostly successful) raids in France in a continuation of the tradition initiated by their (possibly adoptive) father Ragnar Lodbrok.

In 860, Björn had led a large Viking raid into the Mediterranean.

After raiding down the Spanish coast and fighting their way through Gibraltar, Björn and Hastein pillage the south of France, where his fleet over-winters, before landing in Italy, where they capture the coastal city of Pisa.

They proceed inland to the town of Luna, which they believe to be Rome, but Björn finds himself unable to breach the town walls.

To gain entry, he sends messengers to the bishop to say that he had died, had a deathbed conversion, and wished to be buried on consecrated ground within their church.

He is brought into the chapel with a small honor guard, then amazes the dismayed Italian clerics by leaping from his coffin and hacking his way to the town gates, which he promptly opens, letting his army in.

Flush with this victory and others around the Mediterranean (including in Sicily and North Africa), …

…Björn returns to the Straits of Gibraltar only to find the Saracen navy waiting.

In the desperate battle that follows, Björn loses forty ships, largely to Greek fire launched from Saracen catapults.

The remainder of his fleet manages to return to Scandinavia, however, where he will live out his life as a rich man.

The 863 Synod of Metz and the Papal Intervention in Lothair II’s Divorce Crisis

By 863, the ongoing marital conflict of Lothair II, King of Lotharingia, reaches a critical point when a Frankish synod at Metz formally confirms his divorce from Teutberga, his lawful wife, in favor of his mistress, Waldrada. However, the decision is swiftly overturned by Pope Nicholas I, escalating the conflict between the Carolingian monarchy and the Papacy.

The Synod of Metz (863) and Lothair’s Attempt to Secure His Divorce

• The Frankish clergy, under pressure from Lothair II, officially ratifies his divorce from Teutberga, legitimizing his relationship with Waldrada.
• Lothair seeks this recognition to secure an heir, as Waldrada has already borne him children.
• However, Teutberga refuses to accept the ruling, fleeing to the court of Charles the Bald, her powerful Carolingian relative.

Pope Nicholas I Intervenes: The Divorce is Annulled

• Pope Nicholas I, already wary of Lothair’s attempts to manipulate Church law, voids the decision of the Synod of Metz, declaring it invalid.
• He demands that Teutberga be reinstated as Lothair’s rightful wife, rejecting Lothair’s claim that his marriage was invalid.

Political and Ecclesiastical Consequences

• Lothair’s authority is weakened, as his attempt to use the Frankish bishops to legitimize his divorce is blocked by the Papacy.
• Charles the Bald gains political leverage, as Teutberga’s presence at his court reinforces his position as a defender of Church authority.
• The Pope asserts his dominance over secular rulers, setting a precedent for papal influence in royal marriages and European dynastic politics.

Aftermath and Continuing Struggles

• Despite the Pope’s ruling, Lothair continues to resist, leading to further tensions between Lotharingia and the Papacy.
• This conflict foreshadows the growing role of the Church in political disputes, reinforcing the idea that monarchs cannot unilaterally dictate marital and dynastic policies.

The Synod of Metz (863) and Pope Nicholas I’s intervention mark a turning point in medieval European history, highlighting the growing power of the Papacy over royal affairs, a dynamic that will continue to shape the political landscape of Christendom for centuries.
