Iran was a short-term society in contrast to Europe's long-term society.' It was a society in which change - even important and fundamental change tended to be a short-term phenomenon. This was precisely due to the absence of an established and inviolable legal framework which would guarantee long-term continuity. Over any short period of time, there could be notable military, administrative and property-owning classes, but their composition would not remain the same beyond one or two generations, unlike traditional European aristocracies, even merchant classes. In Iran, property and social positions were short term, precisely because they were regarded as personal privileges rather than inherited and inviolable social rights. The situation of those who possessed rank and property - except in very rare examples - was not the result of long-term inheritance (say, beyond two generations before) and they did not expect their heirs to continue in the same positions as a matter of course. The heirs could do so only if they managed to establish themselves on their own merits - merits being the personal traits necessary for success within the given social context. There was thus a high degree of social mobility, unthinkable in medieval and much of modem European history. This did not exclude the position of the shah himself, since legitimacy and the right of succession were nearly always subject to serious challenge, even rebellion.2 The most visible example of the short-term nature of Iranian society is the habit of declaring a building - especially a residential building - as a 'pick-axe building' (sakhteman-e kolangi). Most of these buildings are no more than 30 (even 20) years old, and they are normally sound in foundation and structure. In a few cases they may be run down and in need of renovation, but the feature that results in their condemnation as such, and incidentally wipes off the value of the structure and only leaves the price of their site, is that their architecture and/or interior design is unfashionable according to the latest forms, concepts or whims. Thus, rather than build a
