The opposite of whitewashing; pretending or otherwise revising the historical fact of a scenario in such a way as to demonize all involved parties and lionize any affected persons in a way that contradicts the reality of the situation.
Many people who want to have "Columbus Day" changed to "Native American Day" are guilty of blackwashing: they pretend Native Americans never lifted a finger against Europeans.
