Their first ever march was held in Cardiff on 11 May 2019, with one marcher estimating over 2,000 participants.

Organisers estimated a march in Cardiff on 1 October drew the largest crowd with around 10,000 people. A march in Swansea on 20 May 2023 was led by AUOB and Yes Cymru, attracting almost 7,000 people.
