Accession and rule During 632 or 633
Edwin of Northumbria, with his centre of Christian power north of the River
Humber, was overthrown. Edwin was slain and Northumbria was ravaged by
Cadwallon ap Cadfan, supported by the Mercian king,
Penda. The Mercians then turned on the kingdom of the East Angles and their king,
Ecgric. At an unknown date (possibly in the early 640s), they routed the East Anglian army and Ecgric and his predecessor
Sigeberht were both slain. Penda's victory marked the end of the line of kings of the East Angles who were directly descended from Rædwald. Some time after Penda's victory, Anna became king of the East Angles, though the date of his accession is quite uncertain. The
Liber Eliensis says that Anna died in the nineteenth year of his reign, and since he died in the mid-650s this would indicate a date around 635. However, the
Liber Eliensis is regarded by some historians as unreliable on this point, Throughout his reign he was the victim of Mercian aggression under Penda, but he also seems to have challenged the rise of Penda's power. Due to their rivalry for control over the
Middle Anglian people, Mercia and East Anglia probably became hereditary enemies and Penda repeatedly attacked the East Angles from the mid-630s to 654. Anna arranged an important diplomatic marriage between his daughter Seaxburh and
Eorcenberht of Kent, cementing an alliance between the two kingdoms. It was by means of marriages such as this that the
kings of Kent became well-connected to other royal dynasties. Not all of Anna's daughters were married into other royal families. During the 640s Anna's daughter Æthelburg and his stepdaughter Sæthryth entered
Faremoutiers Abbey in
Gaul to live religious lives under abbess
Fara. The Wuffingas dynasty may have been connected with monastic foundations in the area around Faramoutiers through Anna's predecessor Sigeberht, who had spent several years as an exile in Gaul and had become a devout and learned Christian due to his experiences of monastic life. In 641
Oswald of Northumbria was slain in battle by Penda (probably at
Oswestry in Shropshire). Due to his death, Northumbria was split into two. The northern part,
Bernicia, accepted Oswald's brother
Oswiu as their new king, but the southern
Deirans refused to accept him and were ruled instead by a king of the original Deiran house,
Oswine. Soon afterwards
Cenwalh of Wessex, the brother of Oswald's widow and himself married to Penda's sister, renounced his wife. In 645, according to the
Anglo-Saxon Chronicle, Penda drove Cenwalh from his kingdom and into exile. During the following year, while a refugee at Anna's court, he was converted to Christianity, returning in 648 to rule Wessex as a Christian king. Anna's hold on the western limits of his kingdom, which bordered on the Fen lands that surrounded the Isle of Ely, was strengthened by the marriage in 651 (or slightly later) of his daughter Æthelthryth to Tondberht, a prince of the South
Gyrwe, a people living in the fens who may have been settled in the area around Ely. Æthelthryth, accompanied by her minister Owine, travelled from Ely to Northumbria when she married for the second time, to
Ecgfrith. The monastery was built in about 633 by Fursey after he arrived in East Anglia. In time, weary of attacks on the kingdom, Fursey left East Anglia for good, leaving the monastery to his brother
Foillan. When in 651 Penda attacked the monastery, Anna and his men arrived and held the Mercians back. This gave Foillan and his monks enough time to escape with their books and valuables, but Penda defeated Anna and drove him into exile, possibly to the kingdom of
Merewalh of the
Magonsætan, in western
Shropshire. He returned to East Anglia in about 654.
Death, burial place and successors Soon after 653, when Penda made his son
Peada the ruler of the Middle Angles (but still continued to rule his own country), the Mercian assault on East Anglia was repeated. The opposing armies of Penda and Anna met at Bulcamp, near
Blythburgh in Suffolk. The East Anglians were defeated and many were slain, including King Anna and his son
Jurmin. Blythburgh, a mile from Bulcamp and situated near the fordable headwaters of the
Blyth estuary, was afterwards believed to be the location of the tombs of Anna and Jurmin. Part of an 8th-century whalebone
diptych or writing-tablet, used for liturgical purposes, has been found near the site. Saint Botolph began to build his monastery at Icanho, now conclusively identified as
Iken, Suffolk, in the year that Anna was killed, possibly to commemorate the king. It is possible that Æthelhere was set up as a puppet ruler by Penda or was his ally, as he was one of the 30
duces that accompanied Penda when he attacked Oswiu of Northumbria at an unidentified location called the
Winwæd in 655 or 656. Penda himself was killed at the Winwæd, after having steadily increased his power over a period of 13 years. Æthelhere (who was also slain at the Battle of the Winwæd) and Æthelwold were succeeded by the descendants of Anna's youngest brother, Æthelric. Bede praised Anna's piety in his
Ecclesiastical History of the English People, and modern historians have since regarded Anna as a devout king, but his reputation as a devoted Christian is mainly because he produced a son and four daughters who were all made into
Anglo-Saxon saints. Five hundred years after his death, his tomb at Blythburgh was (according to the
Liber Eliensis) still "venerated by the pious devotion of faithful people". ==Family==
