Bits of History - Irish Problem

It was in the Fifth century AD that St. Patrick introduced Christianity to Ireland, or so it is said. He was born in Britain of wealthy parents. His father was a Christian deacon. At the age of 16 he was abducted by some Irish raiders who were attacking his family’s estates. He was taken to Ireland and was a prisoner for six years. During that period he turned to religion and became a devout Christian. He then escaped to Britain where a voice told him in his dreams to go back to Ireland and spread the gospel. For the next 15 years he studied religion vigorously and was finally ordained as a priest. He then returned to Ireland and began to convert the Irish.

Thus it is not strictly true that St. Patrick introduced Christianity to Ireland, but he sure contributed massively to its spread all over Ireland, North and South, thereby giving the Irish a reason to fight each other for ever.
