[8][9] Nobel played a key role in reshaping the former iron and steel producer to a modern cannon manufacturer and chemical industry participant.[12] When the Treaty of Versailles severely limited Germany from developing new artillery and banned its exports, German military companies started to offshore their R&D abroad, and Krupp, prohibited to develop guns under 17 cm in caliber, started to co-operate with Bofors already in 1919 in order to secretly engage in arms design and manufacture: When, after the end of the war, it became a certainty that, for Krupp, gun production would come to a complete standstill, Krupp concluded an agreement with Aktiebolaget Bofors, a Swedish firm, which made available to Bofors information on Krupp's experiences relative to the production of steel in certain fields, and especially of steel for the manufacture of guns, also a license agreement on the basis of which Bofors was authorized to duplicate some types of Krupp's artillery designs, insofar as they were not classed as secret by the Reich.Under a 1921 agreement the company agreed not to export any Krupp-derived materiel to the victors of WWI: the UK, US, France, Italy and Japan.[16] The arms industry created numerous job opportunities in the 1900s, contributing to the population boom of the city.Throughout its history, the works has been linked to several influential Swedish families such as Robsahm, Liljeström, Flygge, and Ekehjelm.
