This research examines migration in Linares during the third quarter of the nineteenth century, focusing on migration chains. The city experienced a significant increase in population due to the mining boom, which led to an almost sixfold increase in the population over a period of 30 years. Using data from the 1873 population register, which includes more than 22,500 individuals, this study confirms the effectiveness of the migration chain framework in analyzing internal migration during the preindustrial and early industrialization periods. This approach has revealed the significant influence of this form of social capital in determining migratory flows to Linares, highlighting the importance of places of origin in the spatial distribution of the city and in the occupational specialization of the migrant population. The findings suggest that migratory chains played a key role in providing information about opportunities at the destination, as well as in reducing the costs associated with the search for employment and housing.
