Resum	Path dependence analysis explains why history matters by showing how early, sometimes accidental events set in motion self-reinforcing processes that lock in particular institutional or policy trajectories. Drawing on the economics of increasing returns and elaborated for political science by Paul Pierson and for comparative-historical sociology by James Mahoney, the approach holds that once a society starts down a track, the relative costs of reversal rise over time, so that the same initial conditions could have produced very different stable outcomes. Small contingent choices at a formative moment become amplified by positive feedback, learning effects, coordination, adaptive expectations, and sunk investments, until alternatives that were once feasible become prohibitively expensive. The method directs analysts to identify the contingent origin, specify the concrete mechanisms of reproduction, and demonstrate the increasing returns that make a path durable. It thereby converts the loose intuition that the past constrains the present into a disciplined account of temporally ordered, self-reinforcing causation.	Longue duree analysis is the signature method of Fernand Braudel and the Annales school, organizing historical inquiry around the deep, slow-moving structures that shape human possibility across centuries rather than the rapid succession of political events. Braudel famously distinguished three temporalities: the near-immobile time of geography and environment (the longue duree), the medium-rhythm time of economic and social cycles (the conjoncture), and the fast, deceptive time of events (l'histoire evenementielle). The longue duree foregrounds mountains, seas, climate, trade routes, demographic regimes, and collective mentalities as the durable scaffolding within which short-term action unfolds. By privileging structures that change so slowly they appear almost static, the method reorients explanation away from kings and battles toward the material and mental constraints that condition entire civilizations. It demands sources and chronologies measured in centuries, treating the present as a thin film atop vast geological and cultural sediment.
