voting rights for all women. On February 23, 1909, in New York City's Murray Hill Lyceum at 34th and 3rd Avenue, Leonora O'Reilly spoke to over two-thousand audience members explaining the principles of equal rights and demanding women's equal right to vote. This was the first official celebration of the holiday which led a path towards historical accountability for women's rights all over the world. The holiday was not widely celebrated as many American and European socialists were less interested in the suffragist movement as the idea of promoting full women's rights was seen as subordinate to the economic advancement of male working class citizens. There is some controversy between American and European historians and women's rights activists as to when the International Women's Day was first established.

Irish nationalists reasoned that Irish American labor leaders should support the movement as they were fighting for justice and the equality of all workers. Moreover, it was argued that British imperialism damaged American workers, notably related to the elite Anglo-Protestant groups in the US siding with the British and discriminating against Irish American workers. O’Reilly responded positively to Irish nationalists later in her career and became a key figure in international networks that supported the Irish Rebellion. O’Reilly was involved in an array of organizations associated with the Irish Rebellion, including Cumann na mBan (Irish Women’s Council), the Friends of Irish Freedom, the Irish Progressive League, the Labor Bureau of the American Commission of Irish Independence, the American Women Pickets for the Enforcement of American War Aims, and the Irish Women’s Purchasing League. O’Reilly was notable for using her
