In the 19th-century Travancore kingdom, there were many oppressive policies that dictated what the lower classes could and could not do. One such was the mulakkaram, or breast tax. Avarna women weren’t allowed to cover their breasts in public unless they paid this tax (the sources I’ve found vary on whether the amount of the tax varied based on size/attractiveness of the breasts in question). One woman staged a harrowing protest that led to the end of the practice… and her life.
Warning: the link might be NSFW for pictures of naked breasts, and somewhat gory illustrations.
