Abstract: Crisis represents one of the most important factors that lead to radical changes in the city systems within a short period of time, and because of the war being one of the most important causes and results of a crisis; therefore war changes the city systems in different aspects.The war mechanism mainly depends on its destructive energy which affects directly the city systems, as well as its physical and symbolic components; nevertheless, the city constantly tries to balance itself by controlling its changing elements in the reconstruction process to form a new balanced state.A comprehensive theoretical framework capable of building integrated basic concepts about reconstruction of cities influenced by war and its effects on urban patternschange was absent in the literature.This have led to the creation of the basic research problem which is "the lack of a professional knowledge concerned with the concepts of city urban patterns and their changes during crises."Therefore, the aim of the research is to clarify the physical relation between war and the patterns of urban fabric. This will be done by studying the effects of the war massive destructive energy on the urban patterns through related literature such as chaos theory and its applications in mathematical field (fractal geometry) which will help in establishing a database concerned with the concepts of crisis, war, pattern, fractal and change. In order to accomplish this aim the research suggests a main hypothesis, which is "the war may demolish the fractal characteristics of the urban fabric by changing its patterns" and a secondary hypothesis "the reconstruction process plays a vital role in controlling the fractal characteristics of the urban fabric".The research structure comprises chapters discussing the research fundamental concepts by implementing a scientific analytical methodology and chaos theory since the war is an unpredictable state with high energy that follows non linear path and a wide range of probabilities.Chapter One comprises introduction and the literature review which is of great importance in determining research problem, aims, hypothesis, and methodology.Chapter Two discusses the nature of crisis and war by studying their types, conducts, mechanisms, and theories to extract the interrelationship between them; ultimately the chapter ends with discussing their damages to the system.Chapter Three discusses the nature of pattern and its changes by studying its components, types, mechanisms, and theories in order to recognize pattern's necessity for the continuity within the urban fabric.Chapter Four discusses the theoretical framework of war and pattern change by investigating how the crisis may deform the fractal properties of the urban fabric through transforming the existing physical patterns.Chapter Five is the practical application of the theoretical framework which tests a number of regional and international examples by applying the research hypothesi on a number of selected samples and finally proves the validity of the research hypothesis in Baghdad reconstruction proposal.Chapter Six finally ends the research with conclusions and recommendations to sustain the fractal characteristics of cities damaged by wars, through reconstructing structure from the beginning with the appropriate trends of reconstruction; otherwise the inevitable patterns that develop as a result will cut across the original fractal properties.
