Blavatsky used the swastika extensively, incorporating it into the seal of The Theosophy Society (NGC 20, JW 262 and CCM 39).
The first German publication at this time to sport the Theosophical Swastika on its cover was "Lotusbluthen" (Lotus Blossoms).
That was also in 1891 (NGC 25). The Theosophical publication for English children at that time was entitled 'Lotus Journal' (CCM 39).
In 1919, Julius Streicher was the local organizer of the Thule sponsored German Socialist Party (Deutschsozialistische Partei).
In 1921Streicher launched the Deutscher Volkswille, it became the voice of the party. In 1922 Streicher joined the National Socialist German Workers Party and shortly thereafter handed his own party over to its notorious leader, who wrote a glowing account of Streicher's generosity in Mein Kampf (M-3).
Streicher also used alphabetical symbolism when he formed his "Storm Troops" (the SA), and they wore swastika armbands (GP 25).
Edward Bellamy was cousin and cohort to Francis Bellamy, another socialist famous for creating the "Pledge of Allegiance" in 1892.
The early Pledge used a straight-arm salute that was the origin of the salute adopted later by the National Socialist German Workers' Party, as discovered by the historian Dr. Rex Curry, author of "Pledge of Allegiance Secrets." Shocking photos are on the web. http://rexcurry.net/book1a1contents-pledge.html
Francis was a Freemason and he promoted the robotic chanting and the salute within that group and other groups. The Royal Masonic Cyclopaedia (1877) includes the swastika and calls it the Hermetic Cross (Hermeticism was a form of Gnostic Christianity) and refers to its use in Europe (France).
The Bellamys and Blavatsky promoted their dogma through many other civic, religious and philosophical groups.
The Bellamy-Blavatsky dogma was similar to that of many other civic, religious, social and fraternal groups (e.g. Boy Scouts and Girl Scouts) in that it suffers ignorance of economics, markets, prices, trade and private property rights. That deficiency in most groups makes group-members easily misled into socialism. http://rexcurry.net/pledge-of-allegiance-scouting.html
Some people consider Theosophy and Blavatsky the origin of the New Age movement, and that is apropos in that the New Age movement suffers from the same vague socialist dogma.
The Bellamys and Blavatsky saw in their movements a practical means to further their "ideal of universal brotherhood." (see Arthur E. Morgan in his biography, Edward Bellamy, 1948, pp. 260-75; see also The Key to Theosophy by H. P. Blavatsky, pp. 44-5. -- K.V.M.] .
The political product was socialism and self-sacrifice to government by calling it the "greater good."
There was a white supremacist ideology in it, with talk of root races, claiming that the fifth of which, the Aryans, were vastly more "evolved" than the lower races.
Blavatsky openly referred to negros and Indians and "half-human mongrels", though her followers excuse this by claiming that she believed white people were also once black skinned, and because of their personal drive to advance spiritually they were reincarnated as white people. It was basically Hinduism, and difficult to defend (the Hindu connection provides another angle to the swastika as a symbolic symbol of the dogma).
Helena Blavatsky inspired Alfred Rosenberg (who was also inspired by Bellamy's book and may have been the one to introduce it to the Thule Society) though Rosenberg's top interest was antisemitism, inspired by the Protocols of the Elders of Zion, followed by Aryan supremacy (as introduced by Helena Blavatsky):
"The intellectual difference between the Aryan and other civilized nations and such savages as the South Sea Islanders, is inexplicable on any other grounds. No amount of culture, nor generations of training amid civilization, could raise such human specimens as the Bushmen, the Veddhas of Ceylon, and some African tribes, to the same intellectual level as the Aryans ..." (The Secret Doctrine).
Blavatsky also promoted the notion of Brotherhoods and Societies dedicated to the Occult. Where I see Bellamy's book coming in, is with the creation of a perfect society, once they got rid of the Jews and bred an Aryan race. And of course, you can't mistake the military socialism.
