While some scholars have argued that the research related to “Collective Memory” could be traced back to the 18th century or even earlier, it was not until the 1920s that Halbwachs systematically proposed characteristics of collective memory from a sociological perspective. From his works, the study of memory began to develop, and led to a boom in the 1970s, and the launching of the academic journal Memory Study in 2008. Collective memory has now become an interdisciplinary field gaining contributions from different professional perspectives such as literary criticism, psychology, sociology, historiography, cultural studies, and communication studies.
