4. Crafts and trades. Small medieval towns were urban communities, with most of the population engaged in crafts and trades. The range of occupations was not as great as the larger towns, and craft production was largely focused on the needs of the local rural population rather than the requirements of the elite. Although some crafts are largely invisible archaeologically, small towns provide clear evidence for how medieval townspeople made their living. For most medieval towns, documentary sources can only give the broadest insight into occupations: archaeology offers the possibility of obtaining fine-grained and comprehensive evidence.
