Modern Ireland is a relatively wealthy and politically stable democracy, but it bears the deep marks of its route to this point. This introductory chapter draws together some key themes that run through this volume and profiles the core contributions of each of its chapters. The overall story is one of contradictory influences. The political institutions of the state, notwithstanding much innovation over time, retain a bias toward a remarkably strong executive. The long-standing weaknesses of social democratic electoral mobilization both reflect and reinforce a conservative and market-oriented tilt in policy priorities. The ideas that animate public discourse show a creative but sometimes problematic tension between republican and communitarian ideals on the one hand, and liberal ideas and values on the other. Ireland has assumed a confident role on the world stage and especially within the European Union (EU), but relations with its nearest neighbour, the United Kingdom, can often be problematic, not least because of the complexity of the politics of Northern Ireland. And while on many measures Ireland is among the wealthiest of the EU member states, this is not the lived reality for a great many of its citizens, and the nuances of why this is so need to be carefully assessed. Overall, this introductory chapter offers an overview of the whole Handbook while also making an original contribution in its own right.
