Zwentibold (Zventibold, Zwentibald, Swentiboldo, Sventibaldo, Sanderbald; c. 870 – 13 August 900), a member of the Carolingian dynasty, was the illegitimate son of Emperor Arnulf. [1] In 895, his father granted him the Kingdom of Lotharingia, which he ruled until his death. [1]
Zwentibold was born during the long reign of his great-grandfather, King Louis the German in East Francia. He was the first-born, yet illegitimate, son of Arnulf of Carinthia and his concubine Vinburga. Zwentibold's father was an illegitimate son of Carloman of Bavaria, the eldest son of Louis the German. Zwentibold was named after his godfather Svatopluk, ruler of Great Moravia (Zwentibold being a Frankish transcription of Svatopluk). After Louis' death in 876, Carloman ruled over the East Frankish territory of Bavaria and ceded the adjacent marches of Pannonia and Carinthia (former Carantania) to his son Arnulf. In 887 Arnulf succeeded the incapable King Charles the Fat as king of East Francia.
When Zwentibold came of age, he intervened in the scramble for the throne in West Francia between Count Odo of Paris and Charles the Simple, but they began to cooperate against Zwentibold, when it became apparent that he intended to become king of West Francia. The eldest son of Arnulf was at first marked out for his succession in East Francia. According to the 870 Treaty of Meerssen and the 880 Treaty of Ribemont, the Lotharingian kingdom of former Middle Francia had fallen to the East Frankish realm. When in 893 King Arnulf's wife Ota gave birth to his legitimate son and successor Louis the Child, Zwentibold in compensation received the Lotharingian royal title, which last had been held by Lothair II.
In the summer of 893 Arnulf received pleas of intervention against Wido of Spoleto from Pope Formosus and Berengar of Friuli, king of Italy. Arnulf sent Zwentibold down the Brenner Pass with an army who joined forces with Berengar in Verona. The two marched to Wido's capital, Pavia, and besieged it unsuccessfully, finally abandoning the siege. According to Liutprand of Cremona, Zwentibold accepted money from Wido in order to leave, although it is not clear if it was in the form of a personal bribe or a tribute to his father. Zwentibold's retreat was nonetheless seen as a failure, but after learning details of the campaign, Arnulf summoned a stronger army and personally led it to Italy and took Pavia a few months later.
As a part of the plans to integrate Lotharingia into the East Frankish realm, the rule of King Zwentibold was enforced by his father, supported by the archbishops Herman I of Cologne and Ratbod of Trier, against the resistance of the local nobility. As he helped the common population too much, he began to be hated in a few years.[ citation needed ] He was fighting unruly nobles when his father Arnulf died in 899 and the legitimate son Louis the Child became king of East Francia at the age of six. [1]
Zwentibold attempted to take advantage of the succession of his minor half-brother to establish complete independence for his Lotharingian kingdom. However, after he had lost his father's backing, the entire nobility supported Louis and asked him to intervene. In 900, Count Reginar I of Hainault and Odoacer rose against Zwentibold and slew him in battle that year, on the river Meuse, near present-day Susteren. [2] His remains are buried at Susteren Abbey.
After Zwentibold's death, King Louis the Child ruled over Lotharingia. However, under his reign the East Frankish realm disintegrated and from 903 Zwentibold's kingdom was administered by the Lahngau Count Gebhard, a scion of the Conradine dynasty, who received the title of Duke of Lorraine.
In 897, he married Oda, a daughter of Duke Otto I of Saxony. [3] He had three daughters, who are mentioned in the Gesta episcoporum Leodensium :
They also had one son, named Otto de Lorraine. He died in 949.

Arnulf of Carinthia was the duke of Carinthia who overthrew his uncle Emperor Charles the Fat to become the Carolingian king of East Francia from 887, the disputed king of Italy from 894, and the disputed emperor from February 22, 896, until his death at Ratisbon, Bavaria.
The 890s decade ran from January 1, 890, to December 31, 899.
Year 899 (DCCCXCIX) was a common year starting on Monday of the Julian calendar.

Carloman was a Frankish king of the Carolingian dynasty. He was the eldest son of Louis the German, king of East Francia, and Hemma, daughter of a Bavarian count. His father appointed him governor of Carantania in 856, and commander of southeastern frontier marches in 864. Upon his father's death in 876 he became king of Bavaria. He was appointed by King Louis II of Italy as his successor, but the Kingdom of Italy was taken by his uncle Charles the Bald in 875. Carloman only conquered it in 877. In 879 he was incapacitated, perhaps by a stroke, and abdicated his domains in favour of his younger brothers: Bavaria to Louis the Younger and Italy to Charles the Fat.
Louis the Child, sometimes called Louis III or Louis IV, was the king of East Francia from 899 until his death and was also recognized as king of Lotharingia after 900. He was the last East Frankish ruler of the Carolingian dynasty. He succeeded his father, Arnulf, in East Francia and his elder illegitimate half-brother Zwentibold in Lotharingia.
Charles III, called the Simple or the Straightforward, was the king of West Francia from 898 until 922 and the king of Lotharingia from 911 until 919–923. He was a member of the Carolingian dynasty.
Lotharingia was a medieval successor kingdom of the Carolingian Empire. It comprised present-day Lorraine (France), Luxembourg, Saarland (Germany), Netherlands, most of Belgium, and Germany west of the Rhine. It was named after King Lothair II, who received this territory as his share of the Kingdom of Middle Francia which his father, Lothair I, had held.

Charles the Fat was the emperor of the Carolingian Empire from 881 to 887. A member of the Carolingian dynasty, Charles was the youngest son of Louis the German and Hemma, and a great-grandson of Charlemagne. He was the last Carolingian emperor of legitimate birth and the last to rule a united kingdom of the Franks.
Svatopluk I or Svätopluk I, also known as Svatopluk the Great, was a ruler of Great Moravia, which attained its maximum territorial expansion during his reign.
Berengar I was the king of Italy from 887. He was Holy Roman Emperor between 915 and his death in 924. He is usually known as Berengar of Friuli, since he ruled the March of Friuli from 874 until at least 890, but he had lost control of the region by 896.
The Kingdom of Upper Burgundy was a Frankish dominion established in 888 by the Welf king Rudolph I of Burgundy within the territory of former Middle Francia. It grew out of the Carolingian margraviate of Transjurane Burgundy southeast of the Jura Mountains together with the adjacent County of Burgundy (Franche-Comté) in the northwest. The adjective 'upper' refers to its location upstream in the Rhône river valley, as distinct from Lower Burgundy and also from the Duchy of Burgundy west of the Saône river. Upper Burgundy reunited with the Kingdom of Lower Burgundy in 933 to form the Kingdom of Burgundy, later known as Kingdom of Arles or Arelat.
In medieval historiography, West Francia or the Kingdom of the West Franks constitutes the initial stage of the Kingdom of France and extends from the year 843, from the Treaty of Verdun, to 987, the beginning of the Capetian dynasty. It was created from the division of the Carolingian Empire following the death of Louis the Pious, with its neighbor East Francia eventually evolving into the Kingdom of Germany.
Middle Francia was a short-lived Frankish kingdom which was created in 843 by the Treaty of Verdun after an intermittent civil war between the grandsons of Charlemagne resulted in division of the united empire. Middle Francia was allocated to emperor Lothair I, the eldest son and successor of emperor Louis the Pious. His realm contained the imperial cities of Aachen and Pavia, but lacked any geographic or cultural cohesion, which prevented it from surviving and forming a nucleus of a larger state, as was the case with West Francia and East Francia.
Hugh or Hugo was an illegitimate son of Lothair II, king of Lotharingia, by his mistress Waldrada. His father made him Duke of Alsace in 867.
Berengar I was a 9th-century nobleman of East Francia, a son of Gebhard, Count of Lahngau, and younger brother of Udo. He and his brother were created margraves of Neustria by Charles the Bald in 861.
Ratold was a king of Italy who reigned for a month or so in 896. He was an illegitimate son of King Arnulf of East Francia. He and his half-brother Zwentibold are described by the Annals of Fulda as being born "by concubines". Their mothers are not named, and it is possible that their status was only downgraded to that of concubinage after Arnulf's marriage to Uota in 888. They may have originally been in Friedelehen, "consent-based marriages", a kind of common-law marriage.
The March of Carinthia was a frontier district (march) of the Carolingian Empire created in 889. Before it was a march, it had been a principality or duchy ruled by native-born Slavic princes at first independently and then under Bavarian and subsequently Frankish suzerainty. The realm was divided into counties which, after the succession of the Carinthian duke to the East Frankish throne, were united in the hands of a single authority. When the march of Carinthia was raised into a Duchy in 976, a new Carinthian march was created. It became the later March of Styria.
Reginar Longneck or Reginar I, Latin: Rainerus or Ragenerus Longicollus, was a leading nobleman in the kingdom of Lotharingia, variously described in contemporary sources with the titles of count, margrave, missus dominicus and duke. He stands at the head of a Lotharingian dynasty known to modern scholarship as the Reginarids, because of their frequent use of the name "Reginar".
Louis the Younger, sometimes called Louis the Saxon or Louis III, was the second eldest of the three sons of Louis the German and Hemma. He succeeded his father as the King of Eastern Francia on 28 August 876 and his elder brother Carloman as King of Bavaria from 879 to 882. He died in 882 and was succeeded in all his territories, which encompassed most of East Francia, by his younger brother, Charles the Fat, already king of Italy and emperor.
