Porajmos is a very important word in the Romani language, and it means 'the devouring'. It's a name for the killing of Romani people, also known as gypsies, during World War II. During the Nazi invasion of Europe, many Romani were taken from their homes and killed in concentration camps by the Nazis. The Porajmos was one of the worst acts of genocide in history and it is estimated that more than 500,000 Romani people were killed during this time.
