People speaking Insular Celtic languages probably first came to Ireland at the start of the Iron Age, about 500 BC.[2] By around 500 AD, people in Ireland all had the same Goidelic language and culture.[2] Speakers of Old Irish began to move to Britain as Britain became weaker.[2] Other peoples of Britain named these people the Scot.[2]
Old Irish was the only language in the Goidelic languages until Old Irish split into the modern Goidelic languages of Irish, Scots Gaelic, and Manx.[2] These languages are Insular Celtic languages and part of the bigger group of Celtic languages.[2]
