Alternate history is a conceptual framework and analytical approach exploring hypothetical trajectories of historical development by positing specific counterfactual events and examining their potential consequences. This field investigates causality, contingency, and the sensitivity of historical outcomes to specific factors, typically involving the identification of a 'point of divergence' to project plausible alternative timelines based on historical knowledge and logical inference. Its significance lies in illuminating the contingent nature of the past, testing hypotheses about causal relationships, and providing insights into the forces shaping the present by considering what might have been.
