The Welsh League of Nations Union (WLNU), 1918-1946

Predecessor to today’s Welsh Centre for International Affairs (WCIA), the Welsh League of Nations Union (WLNU) was founded in the aftermath of World War 1 to support people Wales-wide in campaigning for Peace and International Cooperation. From Cardiff to Caernarfon, Denbigh to Tenby, the WLNU was part of the fabric of most Welsh communities through the interwar era, with 1,014 community groups and 61,262 members actively involved in the League’s campaigning activities. 390,296 signed the 1923 Women’s Peace Petition to America; 1,025,040 voted in the WLNU-organised 1935 Peace Ballot; WLNU’s Youth Message of Peace & Goodwill continues through Urdd Gobaith Cymru to this day (marking its centenary in 2022); and the Temple of Peace, opened in Nov 1938 as a headquarters ‘befitting one of Wales’ most prominent movements’, continues WLNU’s mission today through the global learning, global action and global partnerships work of WCIA.

The North entrance of Wales’ Temple of Peace and Health proudly retains its WLNU mailbox, an understated reminder of the organisation that was once part of the fabric of every Welsh community: championing the hopes and dreams of a generation for a world without war.

Under the organising leadership of Rev Gwilym Davies, and with the financial support of David Davies of Llandinam and his sisters Gwendoline and Margaret (who particularly supported public education work), the WLNU through the 1920s and 1930s pursued high profile international Peace campaigns that mobilised the Welsh population in support of internationalism, and aimed to strengthen institutions of global cooperation such as the League of Nations, International Labour Organisation, and others.

There was a particularly strong focus on leveraging Wales’ connections with America through the ‘American Welsh’ diaspora – the Women’s Peace Appeal to America of 1923, the Faith Leaders Memorial of 1925, the Kellogg Pact campaign of 1928, and US President Roosevelt and Chief Justice Evan Hughes addressed the opening of Wales Temple of Peace in 1938.

Researching the League: Digitised Records

Their activities can be explored in breadth through the WLNU Annual Reports 1922-45, digitised on People’s Collection Wales and Flickr as part of WCIA’s ‘Wales for Peace’ project. The original booklets, an invaluable resource, can be viewed in both the Temple of Peace Archives, and the National Library of Wales (where an array of records can be explored in the collections of the WLNU, Gwilym Davies and Lord Davies of Llandinam).

WLNU Branch Activities 

A typical ‘Plan of Campaign’ developed by Gwilym Davies with local branches (1922-23 programme for  Newport branch).

Grassroots community participation was at the fore of the Welsh League’s approach, with a comprehensive programme of activities led by local branches and activists. An overview can be gained from the 1922 ‘Plan of Campaign’ for local WLNU Branches drafted by Gwilym Davies. Activities included:

WLNU Membership 1920s-1930s

The table below summarises membership figures from interwar WLNU Reports (with thanks to Rob Laker and Stuart Booker, Swansea University). Years of particularly high membership are spotlighted in bold, with a peak of 61,262 in 1930 (just prior to the Great Depression). Despite a drop in paid memberships the following year, the highest number of branches in Wales – 1,014 – was recorded in 1931-2. The peak in junior branches, at over 302 across Wales, was to come in 1938. Further explanation of the figures is below.











Adult Membership 18,110 26,345 31,299 34,999 36,689 39,223 41,822
Junior Membership 2,686 4,247 6,080 9,801 10,653 11,727 14,784
Total Membership 20,796 30,592 37,379 44,800 47,342 50,950 56,606
Community Branches 280 415 571 652 700 770
764 770
Junior Branches 20 39 77 133 149 176 202 233 244
Total Branches 300 454 648 785 849 946 996 997











Adult Membership 15,146 13,630 13,537 15,675 18,255 12,745 13,018 7,828 4,635
Junior Membership 9,264     9.026 9,290 6,780 9,216 3,881 2,342
Total Membership 24,410 13,630 13,537 24,701
19,525 22,234 11,709 6,977
Community Branches 621   479 533   538 498    
Junior Branches 279   298 200  
Total Branches 900   777 733   840 725    

Whilst impressive by any measure, these figures demonstrate changes that reflect the changing world in which the League of Nations Union was operating:

  • In 1930-31, the ‘apparent dip’ in membership was a change in presentation: due to falling income, the Welsh League Council decided to measure paid memberships. It will be noted that the highest number of active local branches is the same year – suggesting voluntary and campaigner activity remained high.
  • As the Great Depression of 1930-31 took effect, this had 2 impacts: a sharp decrease in paid memberships, reflecting the unemployment and austerity situation; and some loss of faith in the League of Nations itself following the Manchuria Crisis.
  • Further reorganisation in 1934, and some presentational variations, result in some gaps in figures.
  • Highest paid members was in 1937, as Wales’ Temple of Peace was under construction – and as people’s concerns around peace escalated in the leadup to WW2.
  • With the outbreak of WW2, the Welsh League partially suspended work. Some figures are offered – though these may not represent similar measures of activity.
  • Junior Membership / WLNU Branches largely operated out of individual schools Wales-wide. It has been queried whether there was overlap with the Urdd Youth movements local Aelwyd’s or youth branches / chapters, but it seems fairly clear from WLNU Archives that Junior branches were schools based ‘societies’.

Fundraising and ‘Daffodil Days’ 

The operating funds of the Welsh League were generated through widespread Fundraising by Branches, through organising annual Daffodil Days for Peace (explored by Swansea University History student Rob Laker).  

In 1927, branches Wales-wide contributed £1,507 12s 11d – approx. £93,000 today – towards the general running costs of the Welsh League, as well as funding their own local campaigns and activities.

Community, Internationalism and the Campaign for Peace in Interwar Wales – Llafur Talk, Oct 2020

In the aftermath of the First World War, Welsh communities took concerted action in the name of internationalism, peace and equality with increasing frequency and commitment. In this Llafur online event, join us and our guests Craig Owen, Rob Laker, and Emma West, to explore these themes in an interwar context – from the Welsh Women’s Peace Petition of 1923, to the Peace Ballot of 1935 and the opening of the Temple of Peace in 1938.
