In the scientific article, the author analyzed the issue of the formation of women’s suffrage in the United States of America. The meaning of the “conference to discuss the social, civil and religious condition and rights of women” held in Seneca Falls in 1848 is revealed. The role of suffragettes, their complex international connections and strategies for the development of women’s rights are outlined. The achievements of Mary Wollstonecraft, Maria Stuart, Francisca Anneke, Sarah Parker Remond, Stanton, Anthony, Ida Wells, Frances Harper, Churchy Terrell, Alice Paul and the social movement of abolitionists in the process of securing women’s rights, including women’s suffrage, are revealed. The importance of the founding of the International Woman Suffrage Alliance, the International Women’s League, the World Women’s Christian Temperance Union, the International Council of Women, the National Association of Colored Women, the Congressional Union for Woman Suffrage, and the Inter-American Commission on Women is characterized. The emergence of the internationalism of women’s suffrage, the spread of feminism is analyzed. The events and consequences of the struggle for women’s suffrage in the USA are summarized. In particular, it notes that the transnational legacy of the suffrage movement is evident in the ongoing aspirations of US women for full citizenship today. Then, as now, the struggle for women’s rights is linked to global movements for human rights – for immigrant, racial, labor and feminist justice. The internationalism of the women’s suffrage movement shows us that activists and movements outside the USA, as well as a wide range of diverse international causes, were crucial to the organization of what was considered such a quintessentially American right to vote. The emergence of women’s suffrage reminds us how much we have to learn from feminist struggles around the world. We see the prospects for further scientific research in the study of women’s suffrage in the states of the EU and other countries of the world and in their comparison. A scientific article can be useful for experts, historians and students.
