Why was the peasants revolt so dangerous?

The Peasants' Revolt of 1381 was particularly dangerous because it represented a widespread uprising against the ruling class, fueled by deep-seated grievances over economic hardship, oppressive taxation, and social inequality. The revolt saw thousands of peasants marching on London, challenging the authority of the monarchy and threatening the established social order. Its violent nature, including the killing of key figures like Archbishop Sudbury, demonstrated the potential for chaos and instability, prompting fear among the ruling elite. Ultimately, it highlighted the growing discontent among the lower classes, signaling that such unrest could arise again if their grievances were not addressed.
