Erin go Bragh, sometimes Erin go Braugh, is the anglicisation of an Irish phrase, Éirinn go Brách, and is used to express allegiance to Ireland. It is most often translated as "Ireland Forever."
From the emergence of the Irish Patriot Party and its chequered success after 1780, a number of groups such as the Irish Whigs used phrases and slogans like "Erin go bragh" to proclaim an Irish identity, even though the users may not have been Irish speakers. By the time of the 1798 rebellion, the famous London cartoonist James Gillray cruelly portrayed the Patriot leader Henry Grattan as a rebel leader shouting "No Union" (no union with Britain) and "Erin go Brach". Grattan was not a rebel in 1798 but suffered in the aftermath for his liberal views.
