16th–20th century
Between 1500 and 1800, the mass of water flowing through the IJssel decreased, decreasing the importance of Deventer's harbour. The competition with trade centres in Holland, as well as the religious war between 1568 and 1648, brought a decline in the city's economy.
In the 18th century, the iron industry came to Deventer. East of the town, so-called "oer", riversand containing iron, was found as early as 900.

Some of these industries are still thriving today, such as beds and accessories (Auping) and publishing (Wolters-Kluwer, now with headquarters in Amsterdam)

The female Jewish poet and writer Etty Hillesum lived in Deventer during the war before being deported to Auschwitz.
