The aim of this investigative work is to analyse the Board of Dependences of Foreigners, an institution understood in the reform framework of the Government of Felipe V de Borbón, following the Spanish Succession War, which was set up to monitor and control the activities of non-native merchants based in many Spanish cities. Throughout its existence, it also developed a strong capacity for dialogue and responsiveness with the components of those communities. Original primary sources have been used, such as the files processed by the junta, usually requests and complaints from traders and communities, and reports on the appointment of foreign consuls, held in the National Historical Archive of Madrid and the Archivo General de Simancas in its State sections. Correspondence has also been handled from foreign representatives relating to these commercial colonies and notarial deeds and records of the historical archives of Madrid, Cádiz and Murcia. A methodology has been chosen for identifying positions and speeches by both the Spanish Government and the cities’ own foreigners who sent their representations to the central authorities. In short, the requests and complaints from foreign traders and consuls demonstrate the strength of communities that had received great privileges in the second half of the 17th century and were received and dealt with by the Junta with considerable considerations, suggesting a conciliatory attitude on the part of the government, and influenced not only these claims but also the pressure from ambassadors and the limitations of the peace treaties. The Board of Dependences of Foreigners therefore adopted a policy that was very different from the Commercial policy of Carlos II, which protected Spanish trade, and tended to accept requests from traders to respect their tax exemptions and customs relating to their commercial practice, while at the same time considering a different view of the foreign community, of the nation as a Autocéfala corporation, disconnected from the state of its territory of origin and influential the cut and its bedrooms.
