Daly was chairman of the Westport meeting on 8 June 1879, addressed by Parnell and Davitt which finally gave national political impetus to the Land Reform movement.
Daly became vice-president of the new National Land League of Mayo on 16 August 1879, and was elected to the committee of the Irish National Land League founded in Dublin on 21 October 1879, when the Mayo Land League was absorbed into it.
