The Welsh Republican Movement (Welsh: Mudiad Gweriniaethol Cymru) was a Welsh nationalist political party.It was founded in 1949 as a split from Plaid Cymru. The group, some of whom had previously been members of the Labour Party aimed to build a base in industrial south east Wales by focusing on socialism and republicanism rather than on rural affairs, pacifism and the Welsh language.In 1950, the group began publishing a newspaper, The Welsh Republican - Y Gweriniaethwr.
