1900 (, "Twentieth Century") is a 1976 epic historical drama film directed by Bernardo Bertolucci and featuring an international ensemble cast including Robert De Niro, Gérard Depardieu, Dominique Sanda, Francesca Bertini, Laura Betti, Stefania Casini, Ellen Schwiers, Sterling Hayden, Alida Valli, Romolo Valli, Stefania Sandrelli, Donald Sutherland, and Burt Lancaster. Set in Bertolucci's ancestral region of Emilia, the film chronicles the lives and friendship of two men – the landowning Alfredo Berlinghieri (De Niro) and the peasant Olmo Dalcò (Depardieu) – as they witness and participate in the political conflicts between fascism and communism that took place in Italy in the first half of the 20th century. The film premiered out of competition at the 1976 Cannes Film Festival.
The film opens on 25 April 1945, the day Italy is liberated from the fascists. The peasants on an estate in Emilia-Romagna are shown attempting to join the partisans and place the owner of the estate, Alfredo Berlinghieri, under arrest. A middle-aged man named Attila and woman named Regina are seen attempting to flee the farm but are attacked by women labourers wielding pitchforks.
