A crowd of up to 1,000 people marched in Connemara to draw attention to the State's lack of action in relation to Irish speakers' rights.
The protest march was from the office of an Coimisinéir Teanga in An Spidéal to the Department of the Gaeltacht in Na Forbacha.
It was part of a campaign supporting the decision of outgoing Irish Language Commissioner, Sean Ó Cuirreain, to resign after ten years in the role.
A letter to Minister of State Dinny McGinley, which outlined the demands of the protesters, was read out at the protest.
The protesters are demanding that the Gaeltacht Act of 2013 be repealed.
They called for Gaeltacht communities to be guaranteed State service through Irish, without condition or question, within two years.
They also demanded that a special education board be established to cater for the educational needs of Irish speakers in the Gaeltacht.
