Introduction of Christianity
The introduction of

consecrated Palladius a bishop and sent him to minister to the "Scots believing in Christ".
His mission mainly seems to have been to Irish Christians in the east midlands, Leinster, and perhaps east Munster. It is uncertain if he converted any Irish. What little is known of his mission appears to have been successful, though it was later downplayed by partisans of Patrick.
Saint Patrick's dates are uncertain. All that can be said is that he was alive sometime in the fifth century, and was a missionary bishop rather than ministering to Christians. His areas appear to have been Ulster and north Connacht, but very little can be said with certainty about him. Later tradition from the seventh-century onwards is known to be unreliable.

Arrival of the Vikings
During the ninth and tenth centuries, waves of Norse warriors ransacked the countryside. The monasteries were favourite targets for their treasures of golden religious ornaments.
As the eighth century neared its close, religion and learning still flourished, but unexpected dangers approached and a new enemy came, before whose assaults monk and monastery and saint and scholar disappeared. These invaders were the Danes from the coasts of Scandinavia. Pagans and pirates, they were formidable foes both on land and sea.
In Ireland as elsewhere they attacked the monasteries and churches, desecrated the altars, carried away the gold and silver vessels, and smoking ruins and murdered monks attested the fury of their assaults. Under native and Christian chiefs churches were destroyed, church lands appropriated by laymen, monastic schools deserted, and lay abbots ruled at Armagh and elsewhere. Bishops were consecrated without sees and conferred orders for money, there was chaos in church government and corruption everywhere.
In a series of synods beginning with
Ráth Breasail (1118) and including
Kells (1152), at which the
pope's legate presided, many salutary enactments were passed, and for the first time
diocesan episcopacy was established. Meanwhile,
St. Malachy, Archbishop of Armagh, had done very remarkable work in his own diocese and elsewhere. His early death in 1148 was a heavy blow to the cause of church reform. Nor could so many evils be cured in a single life, or by the labours of a single man; and in spite of his efforts and the efforts of others the decrees of synods were often flouted, and the new diocesan boundaries ignored.
