Mine Air Makes Free? Rural Liberty, Materiality, and Agency in Europe’s Long Thirteenth Century

Abstract

Abstract Mines and miners began to proliferate in Europe from the late twelfth century on, in lockstep with the region’s accelerating economic integration and urbanization. Mining communities were often rural and remote, reflecting landlords’ capacity to attract workers through freedoms that echoed the era’s incentives for urban migration. If, according to the adage, “city air makes free,” so apparently did the mine. Yet the specific affordances of mines’ materiality, and the mobility regimes they fostered, shaped distinct social dynamics. These emerge in their complexity when mining ordinances—a new type of legal subgenre—are explored for their handling of matter and movement. Mining legislation attests that the composition of ores, the underground extension of seams, the quality of available tools, and the behavior of gas, water, and air across different topographies were salient factors over which elites had little control. The raw physical constraints on directing the flow of people and matter into, through, and out of mines thus created a network of subterranean agency that translated under certain conditions into exterranean power.
