A Gaeltacht is a district of Ireland, either individually or collectively, where the Irish government recognises that the Irish language is the predominant vernacular, or language of the home. The Gaeltacht districts were first officially recognised during the 1920s in the early years of the Irish Free State, following the Gaelic revival, as part of a government policy aimed at restoring the Irish language.
