[2] He left active politics when the group as a whole merged with the Centre Party and became a writer and publisher, taking over the editing of the highly conservative Södertälje Tidning in 1923.
[3] Eriksson was fired in 1925 for his extremist views and set up his own paper, the Nationen, which became the main outlet for his increasingly hard-line beliefs.

Nonetheless he was close to the Carlberg Foundation and had contact with like-minded groups in Europe and North America, being active until his death in 1965.
