The shaping of global society is now often accompanied with theoretical and spatial developments of an 'Ideal Global City' model. A compiling of such models is tightly dependent on the understanding of the role of civil society and its organizations in modern life ranging from the grassroots to social movements of various kinds. Drawing on the study of past and current concepts of the society-city-grassroots relationships evolution, some empirical studies including three international research projects in which I took part, I came to the following conclusions. History of sociology and political sciences showed that the topic of the citygrassroots (within the frames of philosophy and social sciences relationships) has discussed from ancient times up to now. Civil society forces not only indispensable part of many 'ideal cities' theoretical versions but one of the most important drivers of the development of the conceptual frameworks and projects o future society. With every change of a mode of production i.e. in every 'transition period' of particular society development civil society organizations and movements came to the forefront. In each such period a conflict type of relationships between old institutions and the emerging of new forms of social life is sharpening. The very process of globalization permanently generates new forms of social institutions and public participation in their shaping. To my mind, modern process of globalization has two interrelated sides: according to Z. Bauman and J. Urry, it tend to become totally 'liquid' or mobile and at the same time generated new ideas concerning participation of civil society organizations in construction of safety and wellbeing for all.
