In 1724, a textile factory was established in Schwechat. Schwechat profited massively from the Austrian industrialisation wave of the 19th century, many of the companies established then still existing today (like the famous Dreher Brewery, founded in 1796 by Franz Anton Dreher the Younger). Schwechat became a city in 1924 and was incorporated into Vienna in 1938. The city's oil refinery was a bombing target of the Allied Oil Campaign of World War II, with the southern aviation plant complex of the Heinkel firm (Germany-based at Rostock-Schmarl as "Heinkel-Nord", the Schwechat offices/facility was called "Heinkel-Süd") also targeted in late 1943 and lasting through the spring of 1944.
