Conjunctural History

Conjunctural history studies the medium-term cyclical movements, the conjoncture, that occupy the middle layer of Braudel's tripartite time scheme, between the near-immobile longue duree and the rapid surface of events. Pioneered by Ernest Labrousse in his studies of eighteenth-century French prices, the method reconstructs decade-scale fluctuations in prices, wages, harvests, and production, then asks how these economic rhythms reverberate through society and politics. Labrousse showed that interlocking cycles of grain prices and agricultural revenue could converge into acute crises that strained the social order, contributing to the conditions for revolution. The conjoncture is thus neither the slow structure nor the fleeting event but the oscillating economic mood of a period. By charting these waves with quantitative series and linking their peaks and troughs to social tension, popular unrest, and political rupture, conjunctural history offers a bridge between economic measurement and the explanation of historical change.
