Erin go bragh

In time, the phrase became anglicised. By 1847, it was already in use as Erin Go Bragh. That year, a group of Irish volunteers, including U.S. Army deserters, joined the Mexican side in the Mexican–American War. These soldiers, known as Los San Patricios or Saint Patrick's Battalion, flew as their standard a green flag with a harp and the motto Erin Go Bragh.[3][4] Similar flag designs have been used at different times to express Irish nationalism.[5]

In 1862, when a large number of families on the estate of Lord Digby, near Tullamore, County Offaly, were given notice to quit, a local priest, Father Paddy Dunne, arranged passage for 400 people to Australia. A ship was chartered from the Black Ball Line and named the Erin-go-Bragh.[6] The voyage of the Erin-go-Bragh, a "crazy, leaky tub", took 196 days, the longest recorded passage to Australia.[7] A passenger nicknamed the ship the "Erin-go-Slow", but eventually it landed in Moreton Bay near Brisbane.[8]

A pub in Sydney, Australia, in the 19th century that catered to Irish immigrants was called The Erin-Go-Bragh.[9]

At the height of decades of negotiation regarding home rule in Ireland, in the late 19th century the Irish Unionist Party used the slogan on a banner at one of their conventions, expressing their pride in Irish identity.[10]

In the late 19th century, the Edinburgh football club Hibernian F.C. adopted Erin Go Bragh as their motto[11] and it adorned their shirts accordingly. Founded in 1875 by Edinburgh Irishmen and the local Catholic Church, St Patrick's, the club's shirts included a gold harp set on a green background. The flag can still be seen at a lot of Hibernian matches to this day.

In 1887 a gaelic games club was set up in Clonsilla, Dublin under the name Erin go Bragh GAA. There is also an "Erin go Bragh GAA" club in Warwickshire, England.

In 1906, three Irishmen went to Athens, Greece to compete in the 1906 Intercalated Olympics as an Irish team independent of Britain. They had distinct uniforms and intended to compete for the first time as representatives of their own country. Once in Athens, the Irishmen became aware that the British committee had decided that they would instead compete under the British flag. Peter O'Connor won the silver medal for the long jump. As he was about to receive his medal he rushed towards the flag pole, climbed the pole, and flew the Erin Go Bragh flag, as the Tricolour had not yet received widespread acceptance. The other Irish athletes and a number of Irish-American athletes fended off security for a few minutes while the flag was flown. It was the first time an Irish flag had been flown at a sporting event.[12]

• A traditional Scottish song from the 19th century entitled "Erin-go-Bragh" tells the story of a Highland Scot who is mistaken for an Irishman. The first two verses[13] are:

  My name's Duncan Campbell from the shire of Argyll
  I've travelled this country for many's the mile
  I've travelled through Ireland, Scotland and a'
  And the name I go under's bold Erin-go-bragh
  
  One night in Auld Reekie as I walked down the street
  A saucy big polis I chanced for to meet
  He glowered in my face and he gi'ed me some jaw
  Sayin' "When cam' ye over, bold Erin-go-bragh?"

  In 1969, the band The Wolfe Tones released a song called "Erin Go Bragh" on their LP Rifles of the IRA. The song tells of an armed uprising in Ireland, with all 6 verses ending with "Erin Go Bragh".
• A version of the traditional Scottish song opens Dick Gaughan's 1981 album Handful of Earth.[15]
• The expression is used by Hercule Poirot in the 1990 television adaptation of Agatha Christie's The Kidnapped Prime Minister, in which Poirot suspects an Irish connection.
• Andy Irvine also recorded Gaughan's version of this song, with Patrick Street, on their 2007 album On the Fly.
• The expression was paraphrased by a punning New York Times headline Erin go broke, written by economist Paul Krugman, referring to the post-2008 Irish financial crisis.[16]
• In the 2009 film The Boondock Saints II: All Saints Day Norman Reedus's character Murphy MacManus phrases it as: " It's Irish for, 'you're fucked.'"[17]
