Erin
Erin was the ancient
Gaelic name of
Ireland, given to the land by the
Milesians (according to
Irish mythology and
folklore) after the goddess
Eriu. Nineteenth century Irish nationalists used 'Erin' as an anglicised gaelic name for Ireland, as shown in the catchphrase when speaking of Ireland's experiences with Britain, "Let Erin Remember".
The modern Gaelic name of the country is Eire, or in the genitive case Éireann.
