This chapter provides a bird’s eye-view of how Chinese immigrants in Lima institutionalised avenues of solidarity and mutual aid from the mid to the late nineteenth century. It highlights the organisational capacity of Chinese migrants in Lima to advocate for themselves, provide essential services, and develop a sense of community. Migrant solidarity is thus presented as the institutionalised forms of mutual aid and camaraderie between Chinese migrants. This chapter positions itself as part of the ongoing efforts of the urban solidarity literature to study migrant solidarity from below. It aims to contribute to the efforts of the solidarity literature engaged with the ontological and normative bases of the concept of solidarity and the conceptualisation of migrant solidarity as a transformative social practice. This chapter is based on archival work conducted in Lima as well as on secondary research.
