Interactive timeline showing how turning points and crises created branching paths in twentieth-century conflicts
History is written by decisions not taken
Every turning point splits the timeline: the path chosen versus the path avoided. Drag the slider to rewind history and see how each crisis created two futures — one real, one imagined.

Turning points are not obvious when they happen. Operation Barbarossa appeared unstoppable in its first weeks, yet Stalingrad reversed the entire eastern front. The Tet Offensive was a military defeat for North Vietnam but destroyed American public support for the war. Historians identify turning points retrospectively, looking for the moment when the range of possible futures narrowed. Primary sources from the time often show confusion, not clarity — participants rarely know they are living through history's pivot. The turning point becomes visible only when we can see both branches: the world that emerged and the world that did not.
Know This
Turning points only exist in hindsight — contemporaries saw uncertainty, not inevitability, and historians construct the pivot by comparing what happened against what nearly did.
