she joined the
American Peace Society, of which she became vice president between 1905 and 1911. She collected over one million signatures, signed by supporters from the US, UK, and Germany, for a proposal she had written prior to the second
peace conference in The Hague. On 4 July 1907 she handed this document to the chairman of the conference. Since Eckstein did not see the treaties of this second conference as a success, she organised her own version funded by her own money. She went on to collect six million signatures which she planned to present at the third Hague peace conference in 1914 but the outbreak of the
First World War prevented this. 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. She used to wear white dresses as a symbol of peace. Amongst others, Eckstein worked with
Bertha von Suttner,
Alfred Hermann Fried,
Ludwig Quidde, and
Jean Jaurès. Especially in France and Germany, she also had to deal with opposition and criticism, but was nevertheless nominated for the Nobel Peace Prize in 1913. == World War I ==
