Remember the tenacity of 400,000 Welsh women a century ago. Then use your power to shape events today | Rowan Williams

As we celebrate the return to Wales of the peace petition sent to the US in the 1920s, we should also harness its spirit of togetherness

One significant anniversary in 2023 passed almost without mention. In May 1923, the Welsh women's peace petition was initiated - a plea from the women of Wales to the women of the US, urging the US to take its place in the newly formed League of Nations and encouraging its full participation in the permanent court of international justice, which had come into being in 1922. The text refers to American-Welsh cooperation in the 19th century, and welcomes the steps taken after the first world war to control the arms trade and tackle what we now call human trafficking and the movement of illegal drugs.

These are issues that give it a startlingly contemporary ring. But more startling is the fact that nearly 400,000 women in Wales signed. The petition, with all its handwritten signatures (amounting to several miles' worth of paper), was received formally in Washington DC, and travelled all over the US, as far as the west coast. Housed in a purpose-made chest of Welsh oak, it ended up in the Smithsonian Institution in Washington DC - where, after an initial flare of enthusiasm, it was forgotten for decades. In its country of origin, it was commemorated only by a small plaque in the Temple of Peace in Cardiff.
