Revisiting Feminist Historiography On Women's Activism In Turkey: Beyond The Grand Narrative Of Waves, Sevgi Adak, Selin Cagatay
Revisiting Feminist Historiography On Women's Activism In Turkey: Beyond The Grand Narrative Of Waves, Sevgi Adak, Selin Cagatay
Faculty & Staff Publications
Recent contributions in feminist historiography challenge the reading of women's movements through the waves metaphor and destabilise rigid periodisations. These contributions have triggered debates about the way feminism and women's activism are analysed in the West, but their implications for feminist historiography in non-Western contexts have yet to be discussed. New studies, including our own, on Kemalist and socialist women's activisms suggest that the agendas affiliated with the post-1980 ‘second wave’ of feminism in Turkey had been raised prior to the 1980s. These findings call for critical engagement with the long-established idea that there have been two waves of women's …
