Abstract: Egypt is one of four ancient civilizations acknowledged by the international community as having a time-honored historical legacy and a profound cultural heritage. However, from the 19th century onward, Egypt's cultural development trajectory underwent a significant shift due to the influence of Western colonial powers. Subsequently, with the uninterrupted progression of the nationalist movement, the trajectory of Egyptian history and culture, in addition to the conservation and investigation of cultural heritage, underwent yet another transformation. Museums, as crucial instruments for the conservation and exhibition of cultural heritage, have played a pivotal role in the history of Egyptian cultural research, bearing witness to the transformation in the preponderance of Egyptian historical narratives. This paper examines how historical narratives and cultural developments in Egypt were shaped under the influence of colonialism, with a particular focus on the profound impact of Orientalist theories and practices on the construction of museums about the study of historical and cultural heritage. In the post-colonial period, Egyptian museums have served as conduits for disseminating the country's rich cultural heritage and as instruments for enhancing Egyptian national identity. These institutions have played a pivotal role in the formation of national identity and the "decolonization" of the country's cultural heritage, largely due to their irreplaceable cultural space and their capacity to adapt to changing needs. As Egyptian museums have evolved, they have played a significant role in shaping national identity and contributing to the processes of decolonization and de-Westernization. Furthermore, they symbolize the prospective trajectory of Egyptian national identity within the context of globalization and the emergence of a more interconnected world.
