Why were the mirabal sisters called mariposas?

The Mirabal sisters, known as "Las Mariposas" (the butterflies), were given this nickname as a symbol of their strength and resilience in the face of oppression under the Trujillo Dictatorship in the Dominican Republic. The name reflects their desire for freedom and change, as butterflies represent transformation and beauty. Tragically, the sisters were assassinated for their activism, making their nickname a lasting emblem of courage and resistance against tyranny.
