The word bagad was adopted in 1950 to designate Breton ensembles

The word bagad designates a group or a troop in the Breton language. Jef Le Penven suggested its use in April 1950 in order to name these musical formations in a more authentic way. This name was officialized in July 1950 by Dorig Le Voyer in the pages of the newspaper Ar Soner.
