Concurrently, the disciplines of urban archaeology, urban geography and urban history were defined and developed, enabling an integrated study of historical sources, archaeological remains and the analysis of geographic, architectural and regional data.

However, the theoretical interpretation of ancient and historic cities is still conditioned by the chronological and sociological paradigms established as far back as the 19th and early 20th centuries. Thus, for instance, the classification of cities into Eastern, i.e. "Oriental/Muslim/Middle or Far-Eastern" cities as opposed to "Occidental", i.e. European and North American ones is based, to a large extent, on the 19th century's neo-classical interpretation of historical economy. The accepted periodization of urban history into "Biblical", "Greek", "Roman", "Medieval" or "Early Modern" periods also reflects the ideologies, theologies and identities that created them. In many cases they are culturally or ethnically conditioned and cannot be justified outside of the specific culture that created them. Urban history is sufficiently complex and continuous to sustain different cultural definitions and different types of biased periodizations. As a result, the characterization of specifically defined types of cities such as "Muslim", "Medieval" or "greek" cities became almost self-evident, and the terms themselves, let alone the periodization that created them, was rarely contested.

In light of these conceptual paradigms, our research group will examine the processes of cultural, political, social and religious changes in both past and contemporary urban contexts. Adopting a multidisciplinary apprach and a wide chronological range, the members of the group will address an array of changes in urban structures, such as the formation of new centers of political might, structural changes of the public spaces, the creation of architectural icons, and the expansion and collapse of urban tissues, all in relation to major political, cultural and religious changes.
