In ancient Ireland, Brehons, as part of the leading members of society, would take part in an event which took place every three years on Samhain known as Feis Teamhrach (Festival of Tara) in the House of the Banquets (Teach Moidhchuarta) at the Hill of Tara. The assembly was also originally referred to as an Aonach in prehistoric times. It was a national event with the purpose of resolving any regional disputes regarding title to rank, property and privilege. They would be settled by the lawmakers, the Brehons, and all annals and records would be carefully noted and entered by the Ard Ollams in the official records. The event was founded in a very early period and lasted until 560 AD when the last assembly was held by King Dermot, son of Fergus.
