Ok! And now for part 2 of really long trivia!!!
After studying and preparing for several years, Patrick traveled back to Ireland as a Christian missionary. Although there were already some Christians living in Ireland, St. Patrick was able to bring upon a massive religious shift to Christianity by converting people of power. Says Prof. Owens, "[St. Patrick] is credited with converting the nobles; who set an example which the people followed."
But Patrick's desire to spread of Christianity was not met without mighty opposition. Prof. Owens explains, "Patrick ran into trouble with the local pagan priesthood, the druids: and there are many stories about his arguments with them as well as his survival of plots against them." He laid the groundwork for the establishment of hundreds of monasteries and churches that eventually popped up across the Irish country to promote Christianity.
Saint Patrick is also credited with bringing written word to Ireland through the promotion of the study of legal texts and the Bible, says Prof. Owens. Previous to Patrick, storytelling and history were reliant on memory and orally passing down stories.
Patrick's mission in Ireland is said to have lasted for thirty years. It is believe he died in the 5th century on March 17, which is the day St. Patrick's Day is commemorated each year.
