 Sven Stolpe was active in Swedish literary and intellectual discussion for most of his life.In the early 1930s, he argued for internationalism and argued against aestheticism, but he was also part of the Oxford Group which claimed the necessity of "moral and spiritual re-armament" and later in life, in 1947, he became a Catholic.Among his literary production is a dissertation on Queen Christina of Sweden, who abdicated as a result of her own conversion to Catholicism, which was published in 1959.
