Hagen was first mentioned c.1200, presumably the name of a farm at the junction of the Volme and the Ennepe. After the conquest of Burg Volmarstein in 1324, Hagen passed to the County of Mark. In 1614 it was awarded to the Margraviate of Brandenburg according to the Treaty of Xanten. In 1701 it became part of the Kingdom of Prussia.
After the defeat of Prussia in the Fourth Coalition, Hagen was incorporated into the Grand Duchy of Berg from 1807–13. In 1815 it became part of the new Prussian Province of Westphalia.
The growth of the city began in the 19th century with the mining of coal and the production of steel in the Ruhr Area. Hagen was the scene of fighting during the Ruhr Uprising, 13 March - 2 April 1920 and has a monument to the Ruhr Red Army.
In 1928, Hagen developed into a city of more than 100,000 inhabitants.
During World War II, Hagen was bombed repeatedly, by both the Royal Air Force and the Eighth Air Force. On the night of 1 October 1943, 243 Lancasters and 8 Mosquitoes from the Royal Air Force's Bomber Command attacked the city. According to the Bomber Command Campaign Diary, "This raid was a complete success achieved on a completely cloud-covered target of small size, with only a moderate bomber effort and at trifling cost." Hagen sustained severe damage from that raid, and hundreds of civilians were killed.
After World War II, the town became part of the new state of North Rhine-Westphalia.
Owing to the extensive use of water power along the rivers Ruhr, Lenne, Volme and Ennepe, metal processing played an important role in the region of Hagen in and even before the 15th century. In the 17th and 18th century, textile and steel industries as well as paper production followed.
Hagen is the home of the Suedwestfaelische Industrie- und Handelskammer, as well as Sparkasse Hagen, the local municipal savings bank. The bank's former headquarters, the Sparkasse Hagen tower, was a regional landmark until its demolition in 2004.
The city is heavily indebted and in the process of cutting city services in order to balance its budget.
One of the five branches of South Westphalia University of Applied Sciences is located in the city (also: Fachhochschule Südwestfalen (FH SWF)) which offers various engineering programmes.The inception of this institution in the city dates back to 1824.
Hagen is home to the LWL-Freilichtmuseum Hagen, or Hagen Westphalian Open-Air Museum, a collection of historic industrial facilities where trades such as printing, brewing, smithing, milling, and many others are represented not simply as static displays, but as living, working operations that visitors may in some cases even be invited to participate in. It is located near the Hagen community of Eilpe. The Historisches Centrum Hagen includes the city museum and Werdringen castle. In the Blätterhöhle cave in Hagen the oldest fossils of modern people in Westphalia and the Ruhr were found. Some date back to the early Mesolithic, 10,700 years B.C. It seems that the descendants of Mesolithic people in this area maintained a foraging lifestyle for more than 2000 years after the arrival of farming societies.
