The Welsh Women's Peace Appeal to America was initiated by a gathering of this 'Conference of Women' in Aberystwyth University on 23 May 1923, which took place within a wider programme of public events for the Whit-week annual conference of the Welsh League of Nations Union (WLNU).

Presided over by Mrs Peter (Annie) Hughes Griffiths as chair of the WLNU, opening addresses were offered from Sydney Herbert and Rev Gwilym Davies. A resolution proposing the Women's Peace Appeal campaign was proposed by leading women from Aberdare, Port Dinorwic and Swansea, and an organising committee of 20 women appointed to carry out the campaign.
