Romano-British Christian missionary and bishop in Ireland during the fifth century, Saint Patrick. The Declaration, which Patrick is said to have authored, is where most of what is known about Saint Patrick originates from. He is thought to have been born in a prosperous Romano-British family in fourth-century Roman Britain. His grandpa served as a priest in the Christian church, and his father was a deacon. He was abducted as a slave to Gaelic Ireland at the age of sixteen, the Declaration claims, by Irish pirates.He reportedly worked as a shepherd there for six years, and it was during this period that he allegedly discovered God. 

According to the Declaration, Patrick was instructed by God to run to the coast, where a ship would be waiting to transport him back home. Patrick returned home and later went on to become a priest. 

Tradition has it that Patrick went back to Ireland to baptise the heathen Irish. According to the Declaration, he spent many years evangelising in Northern Ireland and won thousands of souls.

Despite the fact that snakes were not known to live in the area, Patrick's actions subsequently became an allegory in which he drove "snakes" out of Ireland.

According to tradition, he passed away on March 17 and was buried in Downpatrick. Patrick became Ireland's most revered saint throughout the ensuing centuries as a result of the various legends that developed around him.
