This work examines the role of state-led women’s organizations in creating a post-absolutist Thai national identity. It argues that Thai women served as political agents in national and international politics from the Asia-Pacific War to the early Cold War. Intermittently led by La-iad Phibunsongkhram from 1943 to 1957, the National Council of Women’s Culture (samnak watthanatham fai ying, NCW) devised a new ideal of femininity in contradistinction to that of the absolutist era. By encouraging non-royal women to become patriotic citizens through embodying the positions of mother, loyal wive, and helpmeet of their spouses, it enshrined non-royal women as indispensable political agents on par with men in national and international politics. However, while its ideal deposed the absolutist code of femininity that created a spatial and class hierarchy between royal and non-royal women, its enforcement in the bureaucracy exclusively empowered a specific group of bourgeois women—new elites associated with non-royal civil servants and old elites related to the royal court—rather than all women regardless of their class status. By examining critiques around the NCW and female members of the Phibunsongkhrams, this work reveals how gendered criticism is conflated with political commentary directed at women in politics. Ultimately, while the creation of bourgeois ideal of femininity started as a non-monarchical project, the royalists appropriated it as part of royalist history by the late 1960s.
