The modern suffragist movement in Argentina arose partly in conjunction with the activities of the Socialist Party and anarchists of the early twentieth century. Women involved in larger movements for social justice began to agitate equal rights and opportunities on par with men; following the example of their European peers, Elvira Dellepiane Rawson, Cecilia Grierson and Alicia Moreau de Justo began to form a number of groups in defense of the civil rights of women between 1900 and 1910. The first major victories for extending the civil rights of women occurred in the Province of San Juan. Women had been allowed to vote in that province since 1862, but only in municipal elections. A similar right was extended in the province of Santa Fe where a constitution that ensured women's suffrage was enacted at the municipal level, although female participation in votes initially remained low. In 1927, San Juan sanctioned its Constitution and broadly recognized the equal rights of men and women. However, the 1930 coup overthrew these advances.
