María Barzola

María Barzola was a Bolivian miner and trade unionist. She is best known for her death during the Catavi Massacre, a 1942 confrontation between tin miners and the army. Barzola grabbed a Bolivian flag, and then was killed by the soldiers' bullets.

Personal and working life Maria Barzola was a palliri, or rock- breaker. This was a name derived from the Aymara language that was given to female mine-workers who sorted through the rocks pulled up from mines. Many of them came from indigenous backgrounds. Palliris lived a difficult life, described by Gregorio Iriarte as "slaves in modern times, without a man to defend them nor a law to protect them."

A plaza in Potosi is named after her.
