were implemented, and universal suffrage was accepted. Treaty of Versailles and German postwar re-armament Sweden was not a signatory of the Treaty of Versailles, which brought the war to an end, but the Swedish diplomat Marcus Wallenberg (senior), the half-brother of Knut Wallenberg, took part in negotiations at Versailles in relation to Swedish assets in Germany. However, in 1920, Sweden joined the League of Nations, which was formed as a result of the treaty, and so was bound by its restriction of German rearmament. Despite the Versailles restrictions, Swedish firms provided assistance to German counterparts that helped them avoid the restrictions of the treaty, ultimately aiding the rearmament efforts of Nazi Germany before the Second World War. The assistance included assembling Junkers military aircraft and manufacturing artillery weapons for Rheinmetall. References 1910s in Sweden Sweden
