To mark Foreign Affairs’ centennial, we’re looking back at pivotal events that took place over the course of the magazine’s 100-year history. In the archival collections that follow, we explore how, in the pages of Foreign Affairs, leading thinkers and historical figures discussed and debated global developments as they happened—and how their ideas shaped the world today.

We’re releasing new collections throughout the summer in a weekly newsletter, Foreign Affairs Summer Reads. Sign up here.
