"The revolt failed because of intense opposition from the aristocracy, who slaughtered up to 100,000 of the 300,000 poorly armed peasants and farmers."
Quite a slaughter. Today we also have indirect slaughter - billionaires versus the rest of the world.
The medieval days, though, were quite tragic because those peons and farmers were factually slaves, depending on the area (there were a few with less restrictions for a while, but ultimately it was slavery). Some of those wars were briefly won by the peons, but in just about any case where they had some victory, lateron they had a huge defeat. Even those who survived were either later executed, or lost their wealth because those who fought for the aristocrats were often rewarded with possessions of others here. In some european countries there is still "nobility". They still have unfair wealth. They should give that to the people.
