1 ene 1909 año - Divisions in Principles

Descripción:

Caused in part by Holst's writings, there were "dramatic conflicts of principle that were serious enough to result in a schism within the SDAP in 1909. The Marxist wing split from the party and called itself the SDP (Social Democratic Party). Initially Henriette remained a member of the SDAP, but found herself in a somewhat isolated position."
