Nechtan's ecclesiastical reforms are seen as having led to closer links between Pictland and Northumbria, with notable results in artistic forms. His expulsion of Ionan clerics, rather than being a submission to Rome and Northumbria, probably marks the coming of age of an independent Pictish church, which nonetheless remained close to Iona and to Ireland. In addition, it speaks to a very considerable degree of royal control over the church in Pictland, which appears to have been contentious in the ninth century.
