Sans-culottes were a radical group during the French Revolution who were known for their distinctive style of dress without knee breeches (culottes). The term "sans-culotte" was used to describe those who belonged to this group, but it can also be used to describe someone who is poor, working-class, or anti-aristocratic. There are several synonyms for "sans-culotte," including proletarian, plebeian, working-class, commoner, and Jacobin. These terms describe individuals who are not part of the upper class or bourgeoisie and who often have revolutionary or leftist political views. Despite its historical origins, the term "sans-culotte" continues to have political and social significance today as a symbol of resistance against established power structures.
