Congratulations to Kate Laing on the publication of Sisters in Peace: The Women’s International League for Peace and Freedom in Australia, 1915–2015 (ANU Press). In examining the rise of Women’s International League for Peace and Freedom (WILPF), Sisters in Peace provides a gendered history of this country’s engagement with the politics of internationalism. This is a history of WILPF women who committed to peace activism even as Australia’s national identity and military allegiances shifted over time—a history that has until now been an overlooked part of the Australian peace movement. Congratulations Kate!
