St. Patrick was neither Irish nor his name was Patrick

St. Patrick’s Day is a holiday commemorating the death of St. Patrick, the patron saint of Ireland. But in reality, St. Patrick was neither Irish nor his name was Patrick.

His original name was Maewyn and he was born in Scotland in 385. He was kidnapped by Celtic pirates who took him from Scotland to the northwest coast of Ireland, where he set out on a long evangelistic journey. St. Patrick became the first person to preach Christianity in Ireland.
St. Patrick reportedly used the green three-leafed shamrock to explain to the Irish pagans the existence of the Holy Trinity: Father, Son and Holy Spirit.
Some historians say that this celebration is represented by the colour green because it is part of the colour of the country’s flag, others attribute it to the use of the shamrock and most to the fact that Ireland is known as the Emerald Isle because of its scenery.
