Who are the people noted for arriving in Ireland around 500 BCE?

The people noted for arriving in Ireland around 500 BCE are the Celtic people. This arrival marked a significant period in Ireland's history, as the Celts brought with them their culture, language, and social structures. The Celts are associated with the Iron Age and were known for their tribal societies and distinctive art, which influenced the development of Irish culture. Their arrival also played a crucial role in the formation of Gaelic identity that persists in various forms to this day.

In contrast, the Normans came to Ireland much later, in the 12th century, and had a significant impact on Irish society, but their timeline does not align with the 500 BCE mark. The Vikings began arriving in the late 8th century, establishing settlements and influencing trade but were not present in Ireland during the earlier timeline specified. The Anglo-Saxons were primarily involved in the history of England, with their presence in Ireland being minimal and not part of the early Irish cultural landscape that the Celts established.
