This article examines the significance of memory in Harold Pinter's discourse as a political activist. Where memory is a defined area of study in the context of Pinter's writing for stage and screen, and to some extent his poetry, it has received little attention in Pinter's activity beyond the arts. The article looks at both Pinter's interrogation of certain kinds of political memory and the forms of remembering Pinter himself modeled in his role as citizen. In the process, it looks to select features of some of Pinter's plays and to what has been said about them in order to suggest where Pinter's interest in memory as an artist flows into his use for memory as a critic of postwar political history. The conclusion reflects on what Pinter's activism in this mode can offer us as citizens today.
