Alessandro Portelli (born July 8, 1942) is an Italian scholar of American literature and culture, oral historian, writer for the daily newspaper il manifesto, and musicologist. He is currently a professor of Anglo-American literature at the University of Rome La Sapienza. In the United States he is best known for his oral history work, which has compared workers’ accounts of industrial conflicts in Harlan County, Kentucky and Terni, Italy.

On March 24, 1944, Nazi occupation forces in Rome killed 335 unarmed civilians in retaliation for a partisan attack the day before. Alessandro Portelli has crafted an eloquent, multi-voiced oral history of the massacre, of its background and its aftermath. The moving stories of the victims, the women and children who survived and carried on, the partisans who fought the Nazis, and the common people who lived through the tragedies of the war together paint a many-hued portrait of one of the world's most richly historical cities. The Order Has Been Carried Out powerfully relates the struggles for freedom under Fascism and Nazism, the battles for memory in post-war democracy, and the meanings of death and grief in modern society.
