en Architectural History Architectural History Research Paper Research Paper Change is an essential element to Humans and foundation of their lives. Each change though requires its unique<br> conditions. But Change may result in total destruction instead of exaltation if it takes place without considering conditions<br> regarding it&rsquo;s time, place and also without scientific evaluations. There are many factors and reasons for change and<br> transformation and once it happens, consequences would follow. Due to social, managerial and historical events, Iran&rsquo;s<br> society has undergone changes during its modern era. Consecutively, Iran&rsquo;s architecture has too experienced a drastic<br> transformation during the past hundred years and especially in the past six decades which some call this an interruption.<br> Interruption means, the connection between past and present has been cut off. Today as result of this interruption, Iran&rsquo;s<br> society is experiencing an increase in individualism and decrease in social relations. This would seriously question objectives<br> of a utopia.This study is looking to clarify the interruption process and events influencing it in Iran&rsquo;s architecture and<br> urbanization base on three fundamental questions: 1. What are the causes of interruption in historical textures and which<br> factor plays the main role? 2. What is the orientation of master plans, the thinking of the inhabitants and the authorities of the<br> historical context regarding the issue of interruption and continuity? 3. What is the relationship between social relations<br> governing the formation of architecture in historical contexts and the issue of interruption and continuity?This study will be<br> using qualitative paradigm and historical research method to review the selected time intervals. As we progress through the<br> study, we will have a look at the consequences of the disconnection from past in Iran&rsquo;s architecture and urbanization. There is<br> also a time graph which includes influential historical events projecting delicate turning and decision points. Moreover,<br> explaining the consequence of the interruption in Iran is the achievement of this study which would assist others with the same<br> interest with a clearer path throughout the time.
