The remains of a fortress from Celtic times in the valley floor of the Vallée de Rocherel prove an early settlement. From the 12th to the 16th century, the place was a transit point for pilgrims on the Tro Breiz pilgrimage route. The parish was part of the Broons district from 1793 to 1801. It was also part of the canton of Megrit from 1793 to 1801 and has been part of the canton of Broons since 1821 . Trédias has been administratively part of the Arrondissement of Dinan since 1801. Trédias was first mentioned by name as Trediarn in a document from the Abbey of Boquen in 1148. In 1819, the previously independent municipality of Saint-Urielle was incorporated (1806: 302 inhabitants).

The increasing mechanization of agriculture and the high number of those who died in the First World War led to a drop in the number of inhabitants to the lows of recent times.
