won a seat for Galway Borough, which he represented as a member of the Irish Parliamentary Party until 1918. During this period he was active in the Gaelic League and was one of the few Irish MPs to have close links to the Irish literary revival. Along with Joseph Maunsel Hone and George Roberts he founded the Dublin publishing house of Maunsel and Company. He was opposed to the demand for Irish as a compulsory subject for matriculation. He supported the campaign which won the establishment of a Catholic university when he served on the Irish University Royal Commission in 1908. During the debate on the third Home Rule Bill, Gwynn at the request of his party leader John Redmond wrote The case for Home Rule (1911) and was in charge of much of the party's official publicity and its replies to criticism from Sinn Féin. Great War On the outbreak of World War I in August 1914 Gwynn strongly supported Redmond's encouragement of Irish nationalists and the Irish National Volunteers to support the Allied and British war effort by enlisting in Irish regiments of the Irish Divisions, especially as a means to ensure the implementation of the suspended Home Rule Act at the end of an expectedly short war. Gwynn, now over fifty, enlisted in January 1915 with the 7th Leinster Regiment in the 16th (Irish) Division. In July he was commissioned as a captain in the 6th (Service) Battalion, Connaught Rangers and served with them on the Western Front at Messines, the Somme and elsewhere. He was one of five Irish Nationalist MPs who enlisted and served in the army, the others being J. L. Esmonde, Willie Redmond, William Redmond and D. D. Sheehan, as well as former MP Tom Kettle. Together with Kettle and William Redmond he undertook a recruitment drive for the Irish divisions, co-operating with Kettle on a collection of ballads called Battle songs for the Irish Brigade (1915). Gwynn was made a chevalier of the Légion d'honneur in July 1915. In 1916 he was appointed to the Dardanelles Commission. Recalled to Ireland in late 1917 to participate in the Irish Convention chaired by Sir Horace Plunkett, he sided with the Redmondite faction of the Irish Party in supporting a compromise with the southern unionists in an attempt to reach consensus on a Home Rule settlement which would avoid partition.
