Heritage is regarded as our inheritance from the bygone. It is what we live now and what we hand on to the future generations. However, the level of interest varies from country to country. While developed countries have come a long way in this field, developing countries are still struggling to catch up with them. Henceforth, the objective of this paper is to review the history of conservation movements in various cultural and geographic contexts (US, France, and Egypt), and analyze the evolution of the conservation of cultural heritage in a comparative way, besides, to find out the key issues influencing the conservation process. The researcher follows the historical and contextual analysis method to compare among the countries and generate the Inferences. The evolutionary study of these countries provides a broader and deeper understanding of the conservation mechanism which affects the development of the cultural heritage in the other countries.
