Adlersparre was born in Hovermo (now a part of
Berg Municipality,
Jämtland County). Having entered the army at the age of 15, he received from King
Gustav III, in 1791, a secret commission to excite the
Norwegians to rebellion. After the death of the king, he left the army and devoted himself to writing and politics. In 1797–1801, he published the periodical
Läsning i blandade ämnen. The
liberal spirit in which he conducted it brought upon him the suspicions of the government. In 1802, he was elected a member of the
Royal Swedish Academy of Sciences. In 1808 he once again joined the military and received the command of a part of the so-called
western army. Shortly thereafter he was promoted to therank of lieutenant-colonel. He was the leader of a conspiracy of officers and noblemen, among them
Carl Johan Adlercreutz, against
Gustav IV Adolf and triggered the
Coup of 1809 by marching with his army to Stockholm. He was governor of
Skaraborg County from 1810 until 1824 when he resigned. After the coup he supported the new strong monarchy, notwithstanding the liberality of his sentiments. In 1831 he was involved in a controversy for publishing allegedly secret state documents and his private correspondence with various Swedish princes, actions for which he remained unrepentant. He spent the last 25 years of his life residing in Gustafsvik Manor in
Kristinehamn Municipality,
Värmland, where he died in 1835. ==Family==
