This chapter links the theoretical foundations and politics of social memory in relation to the building blocks of the current ‘memory turn’ in the social sciences to social memory in the Israeli context. It also places memory as social, constructed and mediated and it is divided into three main themes, theorising memory in spatial, temporal and social terms. It then pursues a temporal line of inquiry, beginning from Marianne Hirsch's notion of ‘postmemory’. It reiterates memory as a social process. Collective memory is often equated with official memory, popular memory and cultural memory. Claiming the authenticity of collective memories is very evident in Pierre Nora. The Nakba embodies an unbridgeable gap between two qualitatively different periods, pre- and post-Nakba, making generational time a third key element of memory time for Palestinians. It is suggested that it is more apt to think of Nakba commemoration by Israeli Jews as co-memory.
