Tramp!", an American Civil War song written in 1864 by George Frederick Root. "God Save Ireland" commemorated the Manchester Martyrs, executed in 1867 for felony murder for their part in an Irish Republican Brotherhood ambush, and it quickly replaced the previous unofficial anthem, "A Nation Once Again", written in 1845 by Thomas Davis of the Young Ireland movement. "God Save Ireland" was associated with the Irish Parliamentary Party and its eclipse by "The Soldier's Song" after 1916 mirrored the party's eclipse by Sinn Féin.[137]
