摘要	Historical GIS brings the spatial-analytic power of geographic information systems to the study of the past, building databases in which historical places, boundaries, and phenomena are tied to coordinates and to the dates at which they held. Systematized in Ian Gregory and Paul Ell's foundational treatment, the approach addresses a problem ordinary GIS ignores: the geography of the past was not fixed. Administrative units split and merged, borders shifted, towns rose and vanished, so a historical GIS must represent geometry that changes through time. Researchers georeference old maps, digitize past boundaries, encode places in gazetteers, and link tabular historical data, censuses, tax rolls, trade figures, to these time-varying geographies. The result supports genuinely spatial questions: how phenomena were distributed, how patterns clustered or diffused, how distance and terrain shaped historical life. It operationalizes the Annales attention to geography as a force in history, letting scholars map and measure the spatial structures within which past societies acted.	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.
