Focusing on the issue of inter-territorial coordination in corporate experiences that involved States throughout the 20th century, the Congress CORPORATE SPACES AND URBAN SCALES aims at a historical reassessment of corporate primary agencies. In general terms, the target will be the basic organisms that framed the economic activities and the “social cooperation” of the majority of the population. In the Portuguese case, for example, such basic structures comprised the following organizations: ‘houses of the people’ (Casas do Povo), ‘houses of the fishermen’ (Casas dos Pescadores), farmers guilds (Grémios da Lavoura), commercial guilds (Grémios do Comércio), industrial guilds (Grémios da Indústria) and unions (Sindicatos). The goal of this Congress is the cross analysis of this reality in the urban-rural context and in a comparative perspective. In this sense, it will be of interest to scrutinize not only the ideological realm and the founding and deployment processes of the various national corporate experiences, but also their amendments and achievements, in particular those undertaken after 1945, in which other elements should be taken into account, with special emphasis for planning policies.
