ON EVERY TIDE is a wide-ranging and challenging reassessment of the Irish diaspora. Drawing on the latest ground-breaking research, and his own career-long engagement with the complexities of Irish identity, Sean Connolly reveals the forces that compelled millions of Irish men and women to abandon their homeland, and explores their new lives in America, Canada, Australia, New Zealand and elsewhere.

What emerges is an Irish story, but also a chapter in world history. Irish emigrants fled a society blighted by poverty and lack of opportunity. But they also became part of a massive population movement, driven by the requirements of an ever more interconnected world economy, that transported the adventurous and the desperate to new parts of the globe. What distinguishes the Irish from tens of millions of other European immigrants is the position they established in their new homes. Initially treated as a despised and exploited underclass, they created a commanding position, in politics, in the labour movement, and, by the twentieth century, as cultural icons.

From his starting point in the grim realities of Famine and social crisis, Sean Connolly takes the reader forward into the twentieth century, when Ireland itself has become a receiver rather than an exporter of emigrants, and when a reimagined Irishness has become a commodity to be marketed to a global audience. On Every Tide plays directly into wider, contemporary debates about migration, as well as offering a unique and distinctive view of two hundred years of Irish history.
