The bread riots started long before the French Revolution, at least as early as 1724. However, as the century wore on, these riots grew more common. On July 14, 1789, a riot that started as a bread riot ended with the fall of the Bastille.
The bread riots were over bakery pricing of bread. When bread was scarce, which was frequent during this period of French history, the peasantry rioted in the bakery, damaging equipment and spoiling ingredients. The French monarchy had long since intervened, periodically regulating bread prices to ensure the peasants could afford it. Even while the French Revolution was in full swing, bread riots continued, challenging the revolutionary leaders' abilities to govern. Price controls grew stricter as the revolution grew increasingly radical.
