The city of Rome went from a population of 800,000 in the beginning of the period to a population of 30,000 by the end of the period, the most precipitous drop coming with the breaking of the aqueducts during the Gothic War. A similar though less marked decline in urban population occurred later in Constantinople, which was gaining population until the outbreak of plague in 541. In Europe there was also a general decline in urban populations. As a whole, the period of late antiquity was accompanied by an overall population decline in almost all Europe, and a reversion to more of a subsistence economy. Long-distance markets disappeared, and there was a reversion to a greater degree of local production and consumption, rather than webs of commerce and specialized production.
