Horizontalidad
Horizontality or horizontalism is a social relationship that advocates the creation, development, and maintenance of social structures for the equitable distribution of management power. These structures and relationships function as a result of dynamic self-management, involving the continuity of participation and exchange between individuals to achieve the larger desired outcomes of the collective whole.
Origin
As a specific term, horizontalidad is attributed to the radical movements that sprouted in December 2001, in Argentina, after the economic crisis. According to Marina Sitrin, it is a new social creation. Different from many social movements of the past, it rejected political programs, opting instead to create directly democratic spaces and new social relationship.
The related term horizontals arose during the anti-globalisation European Social Forum in London in 2004 to describe people organising in a style where they "aspire to an open relationship between participants, whose deliberative encounters (rather than representative status) form the basis of any decisions," in contrast to "verticals" who "assume the existence and legitimacy of representative structures, in which bargaining power is accrued on the basis of an electoral mandate (or any other means of selection to which the members of an organisation assent)".
