The first written records of native life begin in the 6th century AD, when the founding of the kingdom of Dál Riata took place. This encompassed roughly what is now Argyll and Bute and Lochaber in Scotland and County Antrim in Ireland. The figure of Columba looms large in any history of Dál Riata, and his founding of a monastery on Iona ensured that the kingdom would be of great importance in the spread of Christianity in northern Britain. However, Iona was far from unique. Lismore in the territory of the Cenél Loairn, was sufficiently important for the death of its abbots to be recorded with some frequency and many smaller sites, such as on Eigg, Hinba, and Tiree, are known from the annals.
