 There are much fuller historical sources for Ireland, which suggest that there would have been filidh in Scotland, who acted as poets, musicians and historians, often attached to the court of a lord or king, and who passed on their knowledge and culture in Gaelic to the next generation.At least from the accession of David I (r. 1124–53), as part of a Davidian Revolution that introduced French culture and political systems, Gaelic ceased to be the main language of the royal court and was probably replaced by French.After this "de-gallicisation" of the Scottish court, a less highly regarded order of bards took over the functions of the filidh and they would continue to act in a similar role in the courts of lords in the Highlands and Islands into the eighteenth century.
