Contextualism as a holistic approach in the design of the artificial environment, by understanding the subjective and objective structure of the text and the context as an evolutionary event in physical, natural, historical and socio-cultural dimensions and by linking the perception and reception of the audience with the context, in the pursuit of creating the whole meaning of the environment. It is artificial. The present article seeks to explain the dimensions, features and dominant components in this field by examining the evolution of the theory of contextualism in architecture and urban planning through the expression of the views of experts and examples. In this regard, after examining the background of the subject and stating the relevant definitions, the scope of the discussion of context in architecture and urban planning in the opinions and thoughts of experts has been examined in order to formulate the theoretical foundations of the research, and the position of contextualism in some of the contemporary architectural movements has been scrutinized. The results of the studies indicate that contextualism first paid attention to purely physical dimensions, but in its evolutionary course, it has given its field of study to social, cultural and human development aspects and paid attention to cultural, social, ecological and human communication issues. It has replaced purely formal, stylistic and aesthetic issues. Emphasis on the expansion of human-environment relations. Emphasis on restoring the place, strengthening the position of human values ​​in architecture and urban design, the importance of the social meaning of the environment, the use of environmental capabilities to achieve sustainable development and so on. It is considered one of the strategies of contextual approach.
