It actively encourages the teaching, learning and use of the Gaelic language and the study and cultivation of Gaelic literature, history, music and art. Initially, the Association was concerned with the founding of a Gaelic Festival modelled on the Welsh Eisteddfod. This Festival was called The Mòd and it is a result of considerable endeavors that now, 100 years later due recognition has been granted to the Mod in the form of the Royal assent. The Festival is now known as The Royal National Mòd.
The aims of the Association are to support and develop all aspects of the Gaelic language, culture, history and heritage at local, national and international levels by:
- Promoting the use of the language in everyday community life.
- Promoting the study and development of Gaelic language, literature, music, drama and all other related art forms.
- Actively seeking official recognition and use of Gaelic as a living language and national asset by local, national and European Governments and other agencies, by co-operating with all other organisations engaged in the provision of Gaelic language and culture
- An Comunn Gàidhealach is non-political and non-sectarian, and membership is open to anyone sharing the above objectives
