Adopting a microhistorical approach and narrowing the scale of observation offers Cold War historians invaluable heuristic and narrative opportunities, uncovering little-known, seemingly “small” stories that nonetheless hold significant illustrative and historiographical power. This approach repositions human agency at the center of historical narratives and examines its interplay with broader political, geopolitical, and ideological structures. Drawing on Edoardo Grendi’s famous “exceptional/normal” antinomy, the book reconstructs the story of the evangelical Church of Christ’s mission in Italy – a story that is, at first glance, highly exceptional, but on closer examination proves to be remarkably normal within its broader historical context. The analysis seeks to connect global history with microhistory, bridging the dynamics of world integration, such as the Cold War, with the bottom-up perspectives of long neglected actors. This methodological challenge is compounded by the abundance of primary sources available to historians of post-1945 international relations. By exploring the Church of Christ’s Italian mission, the book highlights the potential of microhistory to enrich global historical frameworks, weaving together large-scale structural forces with the intricate, human-scale dynamics that often drive historical change.
