The historicity of the legends of mighty warriors like Cú Chulainn and immortal rulers like Queen Maeve is examined, along with the question “Are the Irish even Celtic?”, which archeologists question.

The ensuing era of prosperity transformed Ireland into Europe's richest nation, while Rome influenced Ireland before the founding of a new kingdom in Scotland by Irish warlords who would ultimately take over the entire country.
