Explore the lives of over forty men and women - great and otherwise - whose pioneering journeys beyond the Irish shore played a profound role in world history.

The Irish have always been a travelling people. Since 1800 an estimated 10 million people have left the Irish shores, and today more than 80 million people worldwide claim Irish descent. In the centuries after the fall of Rome, Irish missionaries carried the word of Christianity throughout Europe, while soldiers and mariners from across the land ventured overseas in all directions. The advent of the British Empire ignited a slow but extraordinary exodus from Ireland that has continued to the present. In his inimitable fashion, Turtle Bunbury explores the lives of those men and women, great and otherwise, whose journeys - whether driven by faith, a desire for riches and adventure, or purely for survival - have left their mark on the world.
