This research proceeds with a comparative history of the formation of agricultural credit institutions and the legal redefinition of land as a financial asset in the Empire of Brazil and the Empire of France in the second half of the 19th century. The time frame is delimited by the end of the transatlantic slave trade to Brazil (1850) and the reorganization of the country's legislation on the fiscal regime (1896. The working hypothesis is that the creation of mortgage credit banks during the slavery crisis in Brazil took as a model the organization of credit institutions in France and its colonies, mainly in Algeria. Brazilian parliamentary discussions on the expansion of the agricultural mercantile frontier into the interior of the country constantly resorted to the analysis of the creation of credit institutions in France and in its colonies. It can be said that Brazil internalized a colonial model of land appropriation, ecological manipulation and capture of the workforce during the crisis of the slavery system.
