This chapter explores the critical role played by the Irish diaspora during Ireland’s unprecedented financial crisis following the collapse of the Celtic Tiger economy. It examines the endogenous causes of the crisis—overdependence on the construction sector, reckless lending by Irish banks, and government mismanagement—and details the subsequent bailout by the European Union and IMF. In response to growing public discontent and a sense of national humiliation, the Irish government sought assistance from its global diaspora. Prominent Irish-American investors, such as Wilbur Ross and John C. Malone, provided key financial support that helped stabilise national banks and revitalise the economy. Additionally, the Irish authorities launched initiatives like the Global Irish Economic Forum and the Global Irish Network to foster deeper engagement with the diaspora. These programmes leveraged Ireland’s “global tribe” to enhance investment, tourism, and national branding. Despite criticisms regarding elitism and tokenism, events like The Gathering successfully mobilised the diaspora and boosted public revenues. Ultimately, the chapter argues that while diaspora contributions were not solely responsible for Ireland’s recovery, their timely intervention, both symbolic and financial, played a significant part in restoring economic confidence and global credibility.
