A vertical tricolour of green (at the hoist), white and orange, the Irish flag was created in 1848 and was intended to symbolise the inclusion and hoped-for union between Roman Catholics (symbolised by green) and Protestants (symbolised by orange).

When presented to him, Irish nationalist Thomas Francis Meagher said “The white in the centre signifies a lasting truce between Orange and Green and I trust that beneath its folds the hands of Irish Protestants and Irish Catholics may be clasped in generous and heroic brotherhood”.
