Up to this day, Ireland has a history that can never be classified as quiet. The first settlers in the island dated back 8000BC. The Neolithic people build massive stones starting 2000BC. Around 1st century BC, Ireland was conquered by a race called Picts - Irish folklore described them as "Fir Bolg". The Celts came and created a great impact in Ireland. They migrated in Ireland around 350 BC. But they have been established around 150 BC with their Iron Age know-how. They dominated the entire Ireland until 1170 AD to 1600AD.
