In 1875, he was elected a member of the upper house of the Riksdag (which at that time was bicameral), in which he served until 1893: at first for Västerbotten County and later for Blekinge County. He was a supporter of free trade and showed particular interest in defense issues.[5]
Personal life
In 1867 he bought Steninge Palace (Steninge Slott) in Sigtuna Municipality, where he led an extensive social life with people that included Prince Oscar (the future Oscar II). He sold the castle in 1873 and in 1876 repurchased the traditional family property in Alingsås Municipality, where he built a manor house known as Nolhaga slott.[6][7]
In 1870 he was elected to the Swedish Academy of Sciences, of which he became chairman in 1891. He died in Stockholm and was buried at Stadskyrkogården in Alingsås. Adelsköldsgatan near the railway station in Alingsås was named in his honor.
