Between approx. 1880 and 1920 was the town transformed from a military town to a town with much heavy industry within many sectors. The Öresundsvarvet shipyard, which opened in 1917, became the largest employer (with close to 4000 employees in the early 1970s). But the industry was not limited to shipbuilding, and a sugar refinery, several textile industries, fertilizers and other chemical plants, as well as a spectrum of various manufacturing industries, grew up. But after the First World War, the town stopped growing as fast as many other Swedish towns did. And the very last military regiment moved to Hässleholm in 1924. Between the mid-1920s and mid-1970s the town grew from approx. 20,000 inhabitants to 30,000. And after the Swedish municipality reforms reached its end point, in 1974, the municipality counted around 38,000 inhabitants.
