Question: The Synod of Chester led to the battle of the same name that took place in what time period?

<P0-S0> The Battle of Chester (Old Welsh: "Guaith Caer Legion"; Welsh: "Brwydr Caer") was a major victory for the Anglo Saxons over the native Britons near the city of Chester, England in the early 7th century. <P0-S1>  Æthelfrith of Northumbria annihilated a combined force from the Welsh kingdoms of Powys, Rhôs (a cantref of the Kingdom of Gwynedd) and possibly Mercia. <P0-S2>  It resulted in the deaths of Welsh leaders Selyf Sarffgadau of Powys and Cadwal Crysban of Rhôs. <P0-S3>  Circumstantial evidence suggests that King Iago of Gwynedd may have also been killed. <SEP> <P1-S0> Elizabeth Jane Holden "Libby" Lane (born 8 December 1966) is a Church of England bishop. <P1-S1>  Since January 2015, she has been the Bishop of Stockport, a suffragan bishop in the Diocese of Chester. <P1-S2>  She is the first woman to be appointed as a bishop by the Church of England, after its General Synod voted in July 2014 to allow women to become bishops. <P1-S3>  Her consecration took place on 26 January 2015 at York Minster. <SEP> <P2-S0> Theodotus, patriarch of Antioch (?? <P2-S1> –429), in A.D. 420 succeeded Alexander, under whom the long-standing schism at Antioch had been healed, and followed his lead in replacing the honoured name of Chrysostom on the diptychs of the church. <P2-S2>  He is described by Theodoret, at one time one of his presbyters, as "the pearl of temperance," "adorned with a splendid life and a knowledge of the divine dogmas". <P2-S3>  Joannes Moschus relates anecdotes illustrative of his meekness when treated rudely by his clergy, and his kindness on a journey in insisting on one of his presbyters exchanging his horse for the patriarch's litter. <P2-S4>  By his gentleness he brought back the Apollinarians to the church without rigidly insisting on their formal renouncement of their errors. <P2-S5>  On the real character of Pelagius's teaching becoming known in the East and the consequent withdrawal of the testimony previously given by the synods of Jerusalem and Caesarea to his orthodoxy, Theodotus presided at the final synod held at Antioch (mentioned only by Mercator and Photius, in whose text Theophilus of Alexandria has by an evident error taken Theodotus' place) at which Pelagius was condemned and expelled from Jerusalem and the other holy sites, and he joined with Praylius of Jerusalem in the synodical letters to Rome, stating what had been done. <P2-S6>  The most probable date of this synod is that given by Hefele: A.D. 424. <P2-S7>  When in 424 Alexander, founder of the order of the Acoemetae, visited Antioch, Theodotus refused to receive him as being suspected of heretical views. <P2-S8>  His feeling was not shared by the Antiochenes, who, ever eager after novelty, deserted their own churches and crowded to listen to Alexander's fervid eloquence. <P2-S9>  Theodotus took part in the ordination of Sisinnius as patriarch of Constantinople, in February 426, and united in the synodical letter addressed by the bishops then assembled to the bishops of Pamphylia against the Massalian heresy. <P2-S10>  He died in 429. <SEP> <P3-S0> The Synod of Chester (Medieval Latin: "Sinodus Urbis Legion(um)") was an ecclesiastical council of bishops held in Chester in the late 6th or early 7th century. <P3-S1>  The period is known from only a few surviving sources, so dates and accounts vary, but it seems to have been a major event in the history of Wales and England, where the native British bishops rejected overtures of peace from Augustine's English mission. <P3-S2>  This led directly to the Battle of Chester, where Æthelfrith of Northumbria seems to have killed the kings of Powys and (possibly) Gwynedd during an attack on the ecclesiastical community at Bangor-on-Dee.
