The story of the 1831 uprising of workers in Merthyr Tydfil in Wales. The struggle that (for some) used the the Red Flag for the first time in the history of the working class movement.

THE BACKGROUND
In 1829 depression set in in the iron industry
which was to last for three years. As a result Merthyr Tydfil Ironmasters made many workers redundant and cut the wages of those in work. Against a background of rising prices this caused severe hardship for many of the working people of the area and, in order to survive, many people were forced into debt. Often they were unable to pay off their debts and their creditirs would then turn to the Court of Requests which had been set up in 1809 to allow the bailiffs to seize the property of debtors. As a result the Court was hated by many people who saw it as the reason for their losing their property.
Against this background the Radicals of Merthyr, as part of the National movement for political reform, organised themselves into a Political Union in 1830 to lead the local campaign for reform. In November 1830 they called for demonstrations in Merthyr to protest against the Truck System and the Corn Laws. The campaign was actually supported by some local Ironmasters. William Crawshay of Cyfarthfa Ironworks and Josiah John Guest of Dowlais Ironworks, for example, both supported the campaign. By the end of the year 1830 the campaign had broadened to embrace the Reform of Parliament, and the election of a Liberal Government in Great Britain led to a bill being brought before Parliament to reform the House of Commons. The Bill was welcomed by the Merthyr Radicals as a step in the right direction, although it did not give Merthyr a Parliamentary Constituency and only extended the right to vote to the Middle Classes rather than the workers. In April 1831, however, the Bill was defeated in a House of Commons vote, the Government resigned and a new General Election was called to fight on the issue of Parliamentary Reform.
