Olav Hammer has just published an excellent article on "Traditionalism in Sweden" in the International Journal for the Study of New Religions 10.1 (2019): 5–24.
After a general introductory discussion of Traditionalism, Hammer looks especially at three Swedish figures: Ivan Aguéli, Kurt Almqvist (1912–2001), and Tage Lindbom (1909–2001). The most interesting of these sections are those dealing with Almqvist and Lindbom, given that Aguéli has been discussed before.
It it not known how Almqvist first encountered Traditionalism, but he traveled to Switzerland to meet Frithjof Schuon in 1941, becoming Muslim and joining the Maryamiyya. After the war he became Sweden's leading Traditionalist, publishing two Swedish translations of selected works by Schuon and Guénon, and several Traditionalist books of his own, starting with Den glömda dimensionen (The Forgotten Dimension, 1959) and ending with Ordet är dig nära: om uppenbarelsen i hjärtat och i religionerna (The Word is Near to You, On Revelation in the Heart and in the Religions, 1994).
Almqvist's most important reader was Lindbom, originally a prominent member of Sweden's dominant political party, the Social Democrats. Lindbom contributed to establishing the postwar Social Democratic model in Sweden, but then became disenchanted, publishing Efter Atlantis (After Atlantis), which questioned socialism in particular and political ideology in general, in 1951. Some years later he read Almqvist's Den glömda dimensionen, contacted its author, and ultimately also joined the Maryamiya, in 1962, the year in which he published Sancho Panzas väderkvarnar (The Windmills of Sancho Panza), a more thorough attack on modern politics. A number of similar works followed, including Mellan himmel och jord (Between Heaven and Earth, 1970) and Agnarna och vetet (The Chaff and the Wheat, 1974), which Hammer discusses in some detail. Hammer sees Lindbom as "a right-wing political writer par excellence," a Sufi (as a Maryami) whose politics were paradoxically closer to Sayyid Qutb than to Sufism, given that--like Qutb--he dismissed human ideologies and turned instead to Divine authority.
Lindbom is interesting not only as a Swedish Traditionalist but also as a rare example of an explicitly political Schuonian Traditionalist. There are many political Traditionalists, of course, but they generally follow Julius Evola, not Schuon. Followers of Schuon and Guénon may have political views, but they do not normally write about them, given the primacy of the transcendent over the political. Lindbom, however, was well established in political life before he encountered Traditionalism, and first became a Maryami relatively late in life, at the age of 53. This may be why he did not drop his earlier political interests and emphases.
