Title: Dagobert II
Content:  Dagobert was the son of Sigebert III (ruled 632–51/6) and an unknown woman. It is unlikely that he was a son of Sigebert's only known wife, Chimnechild, who survived him. He was thus the half-brother of Bilichild, Chimnechild's daughter by Sigebert. He was named for his grandfather, Dagobert I (623–39). According to the Book of the History of the Franks, which dates to 727, after Sigebert's death, Grimoald, the mayor of the palace and the most powerful official under the king, arranged for Dagobert to be tonsured and placed in the custody of Dido, bishop of Poitiers. Tonsuring rendered Dagobert unfit for the throne, since Merovingian kings always wore their hair long. Dido then sent Dagobert to Ireland. The dating 
Title: 634
Content: King Dagobert I is forced by the Austrasian nobles to put his 3-year-old son Sigebert III on the throne, ceding royal power in Austrasia. He frees himself from dependence on Pepin of Landen, and extends his rule over the Bretons (approximate date).

Title: Dagobert III
Content:  Dagobert III (c.699–715) was Merovingian king of the Franks (711–715). He was a son of Childebert III. He succeeded his father as the head of the three Frankish kingdoms&mdash;Neustria and Austrasia, unified since Pippin's victory at Tertry in 687, and the Kingdom of Burgundy&mdash;in 711. Real power, however, still remained with the Mayor of the Palace, Pippin of Herstal, who died in 714. Pippin's death occasioned open conflict between his heirs and the Neustrian nobles who elected the mayors of the palace. As for Dagobert himself, the Liber Historiae Francorum reports he died of illness, but otherwise says nothing about his character or actions. While attention was focused on combatting the Frisians in the north, areas of southern Gaul began to secede during Dagobert's brief time: Savaric, the fighting bishop of Auxerre, in 714 and 715 subjugated Orléans, Nevers, Avallon, and Tonnerre on his own account, and Eudo in Toulouse and Antenor in Provence were essentially independent magnates.
Title: Dagobert II
Content:  Dagobert II (Dagober(c)tus; Dægberht; died 679) was the Merovingian king of the Franks ruling in Austrasia from 675 or 676 until his death. He is one of the more obscure Merovingians. He has been considered a martyr since at least the ninth century. None of the narrative histories of the Merovingian period give an account of Dagobert's reign, which must be reconstructed from several different sources. Upon the death of his father in 656, he was deprived of the succession and exiled to Ireland to live as a monk. His return to Austrasia was arranged by Wilfrid, bishop of York. He ascended the throne following the assassination of his cousin in 675. During his brief reign he made war on the neighbouring Frankish kingdom of Neustria, signed a peace treaty with the Lombard Kingdom in Italy and reintroduced gold coinage. The only near-contemporary assessment of Dagobert's character portrays him as a tyrant. He antagonized the bishops and imposed new taxes. He was assassinated by a conspiracy of the highest nobility. He was succeeded by his cousin, Theuderic III, king of Neustria, against whom he had previously warred.
Title: Dagobert I
Content:  Dagobert was the eldest son of Chlothar II and Haldetrude (575–604) and the grandson of Fredegund. Chlothar had reigned alone over all the Franks since 613. In 622, Chlothar made Dagobert king of Austrasia, almost certainly to bind the Austrasian nobility to the ruling Franks. As a child, Dagobert lived under the care of the Carolingian dynasty forebears and Austrasian magnates, Arnulf of Metz and Pepin of Landen. Chlothar attempted to manage the unstable alliances he had with other noble families throughout much of Dagobert's reign. When Chlothar granted Austrasia to Dagobert, he initially excluded Alsace, the Vosges, and the Ardennes, but shortly thereafter the Austrasian nobility forced him to concede these regions to 
Title: Dagobert I
Content:   Upon the death of his father in 629, Dagobert inherited the Neustrian and Burgundian kingdoms. His half-brother Charibert, son of Sichilde, claimed Neustria but Dagobert opposed him. Brodulf, brother of Sichilde, petitioned Dagobert on behalf of his young nephew, but Dagobert assassinated him and became sole king of the Franks. He later gave the Aquitaine to Charibert as a "consolation prize." In 629, Dagobert concluded a treaty with the Byzantine emperor Heraclius, which entailed enforcing the compulsory baptism of Jews throughout his kingdom. Besides signing this treaty, Dagobert also took steps to secure trade across his empire by protecting important markets 
Title: Sigebert III
Content:  Sigebert was born in 630 as the eldest son of Dagobert I, King of the Franks, and his concubine Ragnetrude. The king recalled and made peace with Saint Amand, who was previously banished for criticizing the king's vices, and asked him to baptize his new-born son. The ceremony was performed at Orléans and Charibert II, Dagobert's half-brother who was King of Aquitaine at the time, was the god-father. Dagobert assigned the education of Sigebert to Pepin of Landen, who was the mayor of the palace in Austrasia under his father Chlotar II, until 629. Pepin took the young Sigebert and moved with him to his 
Title: 676
Content: Dagobert II, son of the late king Sigibert III, becomes (partly with the help of Bishop Wilfrid) the new ruler of Austrasia, after his predecessor Clovis III is murdered. 
Title: Dagobert I
Content:  Also in 632, the nobles of Austrasia revolted under the mayor of the palace, Pepin of Landen. In 634, Dagobert appeased the rebellious nobles by putting his three-year-old son, Sigebert III, on the throne, thereby ceding royal power in the easternmost of his realms, just as his father had done for him eleven years earlier. In historian Ian Wood's view, Dagobert's creation of a sub-kingdom for his son Sigibert had "important long-term implications for the general structure of Merovingian Francia." As king, Dagobert made Paris his capital. During his reign, he built the Altes Schloss in Meersburg (in modern Germany), which today is
