Early history
In about 300 B.C. Celtic tribes invaded Ireland. They founded 5 kingdoms on the island . The northernmost kingdom, today’s Northern Ireland, was called Ulster.
St Patrick- Patron of IrelandAlthough the Romans did not take control of Ireland their influence was very strong. The Irish probably used Roman coins and the language spoken in parts of Ireland may have been influenced by Latin.
In about 400 A.D. Saint Patrick brought Christianity to the Irish population. He set up churches and other missionaries. Between 800 and 1000 A.D. Vikings raided Ireland. When the Normans invaded Ireland in the 12th century the island was divided into many smaller kingdoms. As time went on English kings started to take control the island.
