Isteri-Sedar (IS—Aware Women) was a women's organization established in Bandung, Indonesia in 1930 by Soewarni Pringgodigdo. It was a radical nationalist group founded on its anti-polygamy stance after the First Indonesian Women's Congress in 1928.[1]
The Socialist Party of Indonesia (PSI) maintained close links with Isteri-Sedar. But after the 1955 elections, the PSI felt that Isteri-Sedar had failed to mobilize women voters for the party and thus the party decided to form a women's wing of its own, Gerakan Wanita Sosialis.[2]
