Book excerpt: In 1939, as war loomed, Peter Gumbel’s Jewish-born grandparents fled Nazi Germany for England. But within a matter of decades, their grandson, appalled by the Brexit referendum, had become a citizen of the country they fled eighty years ago. How had it come to this? Drawing on one family’s migration stories, Citizens of Everywhere explores the nature of belonging amid cycles of pluralism and nationalism. In an increasingly global world, nativist and diasporic impulses pull many people in contradictory directions that can be difficult to even understand. In Citizens of Everywhere, Gumbel grapples with this complexity through his own family history, revealing the personal costs of Britain’s recent isolationist retreat. Along the way, he laments the decline of British pluralism at the worst possible moment—as it rejects the European project and engages in an ill-fated struggle against an ever more interconnected world.
