The Acoma Massacre refers to the punitive expedition by Spanish conquistadors at Acoma Pueblo in January 1599 that resulted in the deaths of around 500 Acoma men killed in a three-day battle, along with 300 women and children. Of the remaining Acoma who survived the attack, many were sentenced to 20-year enslavement and 24 suffered amputations. The massacre was the result of a battle between Spanish colonizers and Native Americans from the Keres Acoma Nation in what is now New Mexico in retaliation for the killing of 12 Spanish soldiers by the Acoma in the previous year.
