The Swiss ethos for solidarity strongly refers to social cohesion inside the various territorial levels of the nation-state. Swiss federalism accommodates diversity and autonomy as the mechanism that accounts for the political and social equilibrium between the shared-rule at federal level and the self-rule at the cantonal level. The relationships vis-a-vis solidarity and federalism are subject to the cultural and territorial complexity of the State, which ascribe a core set of values and duties that strong hold cantons and citizens' peaceful coexistence and well-being. This chapter analyses how solidarity is conveyed implicitly and explicitly within the Swiss legal system, focusing on the direct impact of federalism and diversity on institutional solidarity schemes.
