The Red Eyebrows Rebellion was a significant uprising in ancient China that occurred during the late Han Dynasty, around 18-23 CE. It was named after the rebels who painted their eyebrows red as a symbol of their defiance. The rebellion arose in response to widespread corruption, heavy taxation, and social unrest, leading to a revolt against the ruling powers. The movement was primarily led by discontented peasants and was characterized by its grassroots nature. The Red Eyebrows fought against the Eastern Han government, seeking to restore the power of the Han dynasty and address the grievances of the common people. Ultimately, the rebellion was suppressed, but it highlighted the social tensions of the time.
