1. Ireland is very successful in the Eurovision song contest

It’s the only nation to have won Eurovision seven times, and the only nation to win 3 times in a row. Niamh Kavanagh – In Your Eyes might be the most famous Irish winner. 

2. The earliest evidence of human presence in Ireland is dated at 12,800 BC

A bear bone was found in a cave and had clear cut marks from stone tools. The bone was radiocarbon dated to 12,800 B.C. The bone was found already in 1903 but wasn’t examined with new technology until 2010. 

This means that Ireland was inhabited already in the Palaeolithic era. Previously, the earliest evidence was dated 8000 years old. 

3. More Irish people live abroad than in Ireland

In fact, some 70-80 million people worldwide claim Irish ancestry, but it’s hard to estimate exact numbers. The leading cause for such a number is the massive emigrations due to famine and the search for better opportunities abroad, especially America in the 1800s. 

Australia, Canada, Argentina, and South Africa are some of the countries with the highest amount of Irish descendants, and of course the United Kingdom.

Of course, the official number of Irish born citizens abroad is not 80 million people. There are around 1 million Irish born citizens abroad.

Saint Patrick, the Patron Saint of Ireland was not Irish as many might believe. He was in fact born somewhere in Great Britan, most likely in a town in modern day Wales. 

St Patrick was kidnapped by Pirates and was brought to Ireland though. He was sold into slavery and was there for 6 years before he heard a voice saying that he was supposed to return home.

So, he did, and when he got back to Gret Britain he became a cleric, and later returned to Ireland as a missionary. St Patrick’s Day is widely celebrated today each year on the 17th of March.
