Collective memory refers to the shared pool of knowledge and information held by a group, community, or society. It encompasses the memories, experiences, and narratives that are passed down through generations, shaping a group's identity and culture. This concept helps explain how historical events, such as World War II or civil rights movements, are remembered and interpreted by different communities. The formation of collective memory is influenced by various factors, including media, education, and tradition. These elements help to reinforce certain memories while others may fade or be forgotten. Collective memory plays a crucial role in how societies understand their past and navigate their future.
