Solidarity is a collective moral relation, and political solidarity, more specifically, is “a committed unity of peoples on a range of interpersonal to social-political levels” connecting their actions for a cause. Collective action to bring about social change in political solidarity includes a variety of potential harms for participants and for the collective whole. Although numerous accounts of solidarity describe the assumption of collective risks, I demonstrate that the solidary relation also includes a willingness to take up associated commitments meant both to mitigate social risks from the larger society within which it forms and ensure the ability for some members to contribute from their particularity. In addition, the relation of solidarity itself carries its own set of risks that participants accept with the belief that collective action offers a better prospect for social change than acting alone. Using examples to illustrate what is at stake, I discuss four facets of risk in solidarity: collective risk, personal risk, social risk, and relational risk. Assessing the potential for harm or exposure to danger in solidarity offers a way to think about expectations against domination and fostering trust within the moral relation.
