In the summer of 1381, the people of England had had enough: disease, war, and low harvests had caused great discontent throughout the land. The Statute of Labourers (1351)—which kept wages fixed at a low price—was still in force, while the lowest class in society, the serfs, were the virtual slaves of the lord, forced to work the land for little-to-nothing beyond what was needed for their subsistence. To add insult to injury, the government had imposed 3 successive poll taxes in 1377, 1379, and 1380.
