The Isle of Man had become separated from Great Britain and Ireland by 6500 BC. It appears that colonisation took place by sea sometime during the Mesolithic era. The island has been visited by various raiders and trading peoples over the years. After being settled by people from Ireland in the first millennium AD, the Isle of Man was converted to Christianity and then suffered raids by Vikings from Norway. After becoming subject to Norwegian suzerainty as part of the Kingdom of Mann and the Isles, the Isle of Man later became a possession of the Scottish and then the English crowns.
Pope Caius, also called Gaius, was the bishop of Rome from 17 December 283 to his death in 296. Little information on Caius is available except that given by the Liber Pontificalis, which relies on a legendary account of the martyrdom of Susanna of Rome for its information. According to legend, Caius baptized the men and women who had been converted by Tiburtius and Castulus. His legend states that Caius took refuge in the catacombs of Rome and died a martyr.
Germanus of Auxerre was a western Roman clergyman who was bishop of Autissiodorum in Late Antique Gaul. He abandoned a career as a high-ranking government official to devote his formidable energy towards the promotion of the church and the protection of his "flock" in dangerous times, personally confronting, for instance, the barbarian king "Goar". In Britain he is best remembered for his journey to combat Pelagianism in or around 429 AD, and the records of this visit provide valuable information on the state of post-Roman British society. He also played an important part in the establishment and promotion of the Cult of Saint Alban. The saint was said to have revealed the story of his martyrdom to Germanus in a dream or holy vision, and Germanus ordered this to be written down for public display. Germanus is venerated as a saint in both the Roman Catholic and Orthodox churches, which commemorate him on 31 July.
Saint Macarius of Alexandria was a monk in the Nitrian Desert. He was a slightly younger contemporary of Macarius of Egypt, and is thus also known as Macarius the Younger.
The culture of the Isle of Man is influenced by its Celtic and, to a lesser extent, its Norse origins, though its close proximity to the United Kingdom, popularity as a UK tourist destination, and recent mass immigration by British migrant workers has meant that British influence has been dominant since the Revestment period. Recent revival campaigns have attempted to preserve the surviving vestiges of Manx culture after a long period of Anglicisation, and significant interest in the Manx language, history and musical tradition has been the result.
Gerald of Mayo is a saint of the Roman Catholic Church and Eastern Orthodox Church. Born in Northumbria, the son of an Anglo-Saxon king, he was one of the English monks at Lindisfarne who accompanied Colmán of Lindisfarne to Iona and then to Ireland. This occurred after the Synod of Whitby 664AD which decided against the Irish method of calculating the date for Easter. Colman was an ardent supporter of the Irish traditions; after the synod decided to adopt the Roman computation.
Rigobert was a Benedictine monk and later abbot of the Abbaye Saint-Pierre d'Orbais who subsequently succeeded Saint Rieul as bishop of Reims in 698. He is venerated as a saint in the Catholic Church.

Erc mac Dega, also known (incorrectly) as Herygh, was an Irish saint. He was active in Cornwall. Tradition ascribes the foundation of the original monastery on the Hill of Slane to him.
Saint Patrick was a fifth-century Romano-British Christian missionary and bishop in Ireland. Known as the "Apostle of Ireland", he is the primary patron saint of Ireland, the other patron saints being Brigit of Kildare and Columba. Patrick was never formally canonised, having lived prior to the current laws of the Catholic Church in these matters. Nevertheless, he is venerated as a Saint in the Catholic Church and in the Eastern Orthodox Church, where he is regarded as equal-to-the-apostles and Enlightener of Ireland.
Saint Conan was a bishop of the Isle of Man and an Irish missionary.
There is archaeological evidence of insular monasticism as early as the mid 5th century, influenced by establishments in Gaul such as the monastery of Martin of Tours at Marmoutier, the abbey established by Honoratus at Lérins; and that of Germanus at Auxerre. Many Irish monks studied at Candida Casa near Whithorn in what is now Galloway in Scotland.
Philip Moore Callow Kermode, was a Manx antiquarian, historian and naturalist.
Roolwer, also known as Hrólfr, was an eleventh-century ecclesiast. He is the first named bishop of a jurisdiction which later became the Diocese of the Isles, and appears to have served at his post before, and perhaps during, the reign of Gofraid Crobán, King of Dublin and the Isles. Roolwer's name appears to correspond to the Old Norse Hrólfr, which could mean that he is identical to either of two contemporary like-named bishops of Orkney. Roolwer's predecessor in the Isles may have been Dúnán, whose death in 1074 during the Dublin overlordship of Toirdelbach Ua Briain, King of Munster, may have enabled the ecclesiastical separation of Dublin from the Isles. The site of Roolwer's cathedral is unknown, although Maughold and St Patrick's Isle are possibilities.
