Među križom i polumjesecom

This thematic study brings together a series of documents that testify to the secret correspondence between the Spanish Crown and the Republic of Dubrovnik in the 16th century, thus shedding new light on this "obscure" diplomacy. Namely, these are secret, often coded, reports (via trade connections of Ragusans or Ragusan citizens who lived there, and foreigners who crowded Dubrovnik at the time) about the state, intentions and movements of the Turkish land and naval power in the territory from Persia to Croatia, i.e. the sea belt from the west coast of India to the islands in the western Mediterranean. The aforementioned reports were regularly sent to this powerful monarchy on the Iberian Peninsula in the period from 1533 to 1592. The documents containing this secret correspondence are stored in the Spanish state archive (Archivo General de Simancas), and for the purposes of this edition they have been transcribed and published originally in Spanish, alongside summaries in Croatian.
