The open-field system of preindustrial European agriculture involved villagers farming strips of land in common fields and grazing livestock on common land. This system had disadvantages like inefficient use of land and spreading of diseases. The enclosure movement from the 1700s saw wealthy landowners enclose and consolidate the open fields and common land. This allowed for more efficient farming practices like crop rotation and selective breeding. While enclosure increased agricultural productivity, it deprived many villagers of access to common lands and led to unemployment and migration to cities for work in the Industrial Revolution.
