Notable speakers over the years have included Mary Robinson, Gordon Brown, Donald Dewar and Jack McConnell.
A number of Sabhal Mòr Lectures have marked significant turning points in Scottish Gaelic language issues or caught the spirit of the day in striking ways which met with resonance in the Scottish Gaelic-speaking community.
Mary Robinson's lecture spoke of the possibility of creating an island space for the Hebrides and Ireland in which to celebrate what the two countries share.
In his 1999 lecture, Gordon Brown famously declared: What a bland and uniform place this Britain of ours would be if Britishness meant we all spoke the same way, sang, danced and celebrated the same way.
