Bertha von Suttner dies in Vienna from stomach cancer.
On June 21, 1914, Bertha von Suttner passed away in Vienna due to stomach cancer, just days before the outbreak of World War I. Her death marked the end of a life devoted to the cause of peace. Suttner's passing was a significant loss to the peace movement she so passionately led. This event also underscored the urgency and timelessness of her advocacy efforts, as the conflict she worked so hard to prevent began mere weeks after her demise, illustrating the vulnerability of peace in a volatile international landscape.
