The "Julich-Klevischen Erbfolgestreit" (war of the Julich inheritance dispute) erupts in the region around Hattingen and Blankenstein. The protestant Hattingen is occupied by catholic troops until 1630. Count Henrich zu Stolberg-Wernigerode buys 76 morgens of land at Bruch manor in Welper and starts to build a steel-works there. It is called the Henrichshutte and will be one of the most important working places in the region for over 135 years.

During the industrial revolution, coal mining becomes the main economic activity in Hattingen. The city's infrastructure is modernised: the first railway in the world runs through Hattingen. Five city gates are built and the right to hold three fairs a year is granted.

The Henrichshutte is converted into a museum and opened to the public. The municipal area is enlarged by the communities of Blankenstein, Buchholz, Holthausen and Welper. The industrial museum at Heggerstrasse reminds of the heyday of the metal work.

The community is reorganised again: a newer, bigger city is created consisting of the city of Hattingen and most parts of Blankenstein as well as the communities of Bredenscheid-Stuter, Niederwenigern, Oberelfringhausen, Oberstuter and Winz.
