The concertina project begins with a depiction of arguably one of the most famous uprisings: the Peasants' Revolt of 1381. Led, primarily, by Wat Tyler, John Ball and Jack Straw, leaders of the peasantry whose greviances had been building up over a few decades since the catastrophe of the Black Death, which completely upturned society, making way for various shifts, such as power relations in favour of the lower class (peasants, vagrants etc..), if only briefly until authorities implimented the Ordinance of Labourers of 1349 in an attempt to cap wages at pre-plague levels, impose price controls, and demand that able-bodied people under 60 to work; and the Statute of Labourers of 1351, which was an attempt to restrict peasants' movement and regulating the labour force in response to its shortage. However, these measures were never all that successful, and only increased the politicisation of the lower classes, which continued throughout the following centuries. This being made evident with the cluster of other political and heretical uprisings occurring across Europe in the same decade as the Peasants' Revolt; with two in particular being more successful by holding regional government (Florence, 1378-82; Liege, 1384 - both workers' governments). It should be noted however, that although the English Peasants'Revolt was suppressed, Feudal serfdom ended soon afterwards.
All this social turmoil paints an important picture of the beginnings, or at least a more concrete idea, of class struggle and consciousness during the 14th century.
