We trace its gradual evolvement from a backwater town into a 21th century capital to piece the picture of our town together from separate puzzles in names and events. The history of our town with its colonial, soviet and post-soviet periods is impetuously losing its two original contexts. The new city was not built anew, from scratch, but was further constructed, extended and novelized. However the first two periods are effaced and pushed to the background, becoming an apophasis. The questions to puzzle out are： Why the town was renamed so many times into Akmolinsk, Tselinograd, Akmola, and Astana; why it had a few emblems on its record; and from which year starts settlement of the territory this modern city currently takes up. Then comes another moot point： How many times was our town＇s status put to question？ Of special interest is street renaming and monuments＇ relocation and the town＇s demographic constituent is no less a serious subject of research. Our town formed through permanent movement of the rural population to it, which concurred with the governmental campaigns in the epoch in question. Urban environment certainly told on inter-relations, and brought about problems. One of them is the problem of tolerance, inevitably arising in any big city. The problem of misunderstanding between the residents of former Tselinograd and present Astana is generation gap. For permanent population＇s rotation practically no urban life traditions have taken on a definite shape among majority of the residents, paradoxical as it is. The population＇s intent to cast off all the colonial and soviet past ended in the loss of representative opportunities of the ＂old＂ town.展开更多
