There was a first settlement about 1200 A.D., which became a city in 1284. In the following century, Flensburg became the economic centre of the Duchy of Schleswig. In 1409 there were battles between people of the Duchy of Holstein and the Danish crown about the control of Schleswig. In 1412 and 1500 there were bad plagues in Flensburg. In 1485, there was a big fire in the city.

Between 1460 and 1864 Flensburg was the second most important harbour in Denmark after Copenhagen. Since the 16th century Flensburg was an important place for trade. Flensburg became part of Prussia in 1864, after the Danish-Prussian War.

In 1920, there was an election in Schleswig. The vote was to decide whether people wanted to belong to Denmark or Germany. Flensburg and regions south of the city decided to stay German, while regions north of the city chose to become Danish.

In 1945, many Germans were driven out of their homes in the eastern German provinces. These people went to Flensburg. The city had more than 100,000 inhabitants for a couple of years. Nowadays Flensburg has about 85,000 inhabitants.
