1911 South Wales anti-Jewish riots
The 1911 South Wales anti-Jewish riots were a series of antisemitic riots that occurred in South Wales in the summer of 1911.

Background 
In the first years of the 1910s, before the beginning of World War I, Wales saw a significant period of unrest, known as the Great Unrest and centered around labour disputes, including the Miners Strike of 1910-11.

Riots 
On the evening of 19 August 1911, a group of miners in the town of Tredegar that had been drinking at a local pub decided to attack a local shop owned by Jewish family, accusing the shopkeeper of overcharging miners. The attack quickly grew into a riot, involving more than 200 rioters and ransacking 20 Jewish-owned businesses. 15 people were recorded injured, however, none with serious injuries. The riots would spread to neighbouring villages in South Wales in the following days, including Caerphilly, Ebbw Vale and Bargoed. After several days, the chief constable in Monmouthshire called on the Home Office for help dealing with the riots. On 29 August, Home Secretary Winston Churchill ordered the deployment of the Worcestershire Regiment from Cardiff to put an end to the riots, describing it as a "pogrom," and the riots came to an end.

In early September 1911, 46 people were charged by the authorities over their roles in the riots, with the lawyer in charge of the prosecutions noting that they "were people who were generally considered respectable, the majority being colliers in regular employment and the wives of colliers."

The South Wales Baptist Association, which was influential in the region, refused to condemn the riots.

Role of antisemitism 
Despite the fact that the riots particularly targeted Jewish-run businesses, the relative role of antisemitism and general unrest over poverty has been debated by some historians. Historian William Rubinstein has argued that the role of antisemitism has been overemphasised to be used as an anti-devolution argument, saying that "rioters had issues with Jewish businesses, but that's not the same as being anti-Semitic." However, historian Geoffrey Alderman argued that the role of general economic unrest had been overemphasised in accounts of the riots, stating that there was evidence of "clearly anti-Semitic behaviour amongst the rioters." The Monmouthshire chief constable's report on the riots at the time stated that there was "a determination expressed by the inhabitants to get rid of [the Jewish population]," while the chief magistrate of the trials stated that "the first disturbances were no doubt anti-Jewish." Some reports have indicated that the riots may have been pre-arranged, including one read out by Liberal Party MP Arthur Markham on 22 August 1911, which stated that "there can be no doubt that this had been pre-arranged, although the police had no knowledge that such an attack was likely to take place. There were only eight constables available, and they were quite inadequate to deal with the disturbance, and could do little more than look on at the wrecking and looting or eighteen shops owned by Jews or persons of Jewish extraction."
