Between the early 1600s and the 1950s, more than 20 million people left the British Isles to begin new lives… — Niall Ferguson

Between the early 1600s and the 1950s, more than 20 million people left the British Isles to begin new lives across the seas. Only a minority ever returned. No other country in the world came close to exporting so many of its inhabitants. In leaving Britain, the early emigrants risked not merely their life savings but their very lives. Their voyages were never without hazard; their destinations were often unhealthy and inhospitable. To us, their decision to gamble everything on a one-way ticket seems baffling. Yet without millions of such tickets – some purchased voluntarily, some not – there could have been no British Empire. For the indispensable foundation of the Empire was mass migration: the biggest in human history. This Britannic exodus changed the world. It turned whole continents white.
