Finally, looking at activists multiple affiliations can constitute a useful way of comparing the structure of particular movements in different periods, and of tracing its modifications over time. In their pioneering study of the organizational affiliations of 202 key figures in the women's movements of the state of New York between 1840 and 1914,naomi Rosenthal and her collaborators reconstructed the structure of the inter organizational networks in three different historical phases, identifying the central organizations in each phase. A phase of powerful activism between 1840 and the end of the 1860 saw numerous overlaps between participation in women's organizations and in antislavery or temperance organization. The following phase, until the end of 1880, saw a reduction in conflict, and in contrast to the previous phase was characterized by the disappearance of many organization and by the difficulty of revitalizing organizations of national importance between 1880 and 1914, three was a revival of activism and a new intensification of multiple affiliations, corresponding to campaigns for universal suffrage.
