In 1909, Eckstein attended the second National Peace Congress in Chicago, USA, where she read a "World Petition to the Third Hague Conference".[8] The same year, she moved back to her birthplace Coburg. From there she continued to travel to most European countries, and also Australia, New Zealand, Japan, and China, where she gained increasing support for her cause.
