The transition from early trade-centre to medieval town in Deventer in the light of socio-economic changes 900–1200

Recent research in the eastern Dutch town of Deventer provided indications of structural changes in building and infrastructure in the 11th, 12th and early 13th century: a period in which the town was at its highlight as an early merchants-centre. In this paper a first, preliminary attempt is made to connect them with models of changes in social and economic structures.
