James Joseph (Seamus) Hughes (Irish: Séamus Seosamh Ó hAodha; 18 May 1881 – 23 January 1943) was an Irish trade unionist, revolutionary, composer, and public servant.
In 1913 Hughes, who by this time had become affiliated with the socialist James Connolly, was involved in journalism and wrote articles supporting the strikers during the Dublin Lockout.[1]
Following the Anglo-Irish treaty and the ensuing Irish Civil War, Hughes supported the Pro-Treaty faction. This affiliation subsequently saw Hughes move away from his previous ties to the Labour movement in Ireland and join the ranks of Cumann na nGaedheal. Hughes was quickly made the party's first-ever secretary.[1]
During the 1920s, in parallel to his move from Labour to Cumann na nGaedheal, Hughes became associated with Catholicism conservatism: In 1924 he began writing for the Catholic Herald, while in 1926 he joined the highly conservative An Ríoghacht organisation. In 1930 he joined the Catholic fraternal organisation the Knights of Columbanus while in 1936/1937, he was a member of the Irish Christian Front, an anti-communist organisation which supported the Nationalists in the Spanish Civil War.[1]
