After what was basically a depression in Paris, this was the march of hungry people who walked from a Paris fish Markey to Versailles. This started out peacefully, intending only to let the king know what was going on, but they grew increasingly agitated as the march drew on. After they'd finished the 15 mile journey to Versailles, they were furious! So they invade the National Assembly with pikes, scythes, etc! They slaughtered the swiss guards, and try to get at Marie Antoinette! But eventually, they are stopped by LaFayette, who says he'll take the royal family back to Paris if they are spared. However, this changes the dynamics of the revolution because now the royal family was essentially Paris's hostage. SIGNIFICANT BECAUSE IT EVENTUALLY LED TO A CONSTITUTIONAL MONARCHY.
