"Amhrán na bhFiann" ("The Soldiers' Song") is the national anthem of the Republic of Ireland. Written in English by Peadar Kearney and set to music by Patrick Heeney in 1907, it was translated to Irish by Liam Ó Rinn in 1923; the Irish-language version is considered the official anthem. "God Save Ireland" was used from the 1870s until independence.
