The series contains many letters and official documents. Letters to the Republic were written by various Ottoman dignitaries, from the grand vizier to local authorities of the towns and places near the Dubrovnik border. Official documents are orders and charters of sultans, orders of the governors of the Ottoman provinces and various documents of kadis. The documents in the series Acta Turcarum provide an excellent insight into all aspects of relations between the Ottoman Empire and the Republic of Dubrovnik, from interstate to personal. The series contains a small number of documents in other languages: Armenian, Arabic and Judeo-Spanish.

The series also contains a small number of documents in Judeo-Spanish, written in Latin alphabet and Hebrew (vol. E17b, E18a, E18b, D, XXIII). It also contains inventories of main figures of Jewish families and of the houses in which they lived (1756, 1808), as well as an inventory of Jews who immigrated to Dubrovnik in the period from 1730 to 1756. In addition, there are two letters in Italian: a letter written by Abram Bussara, the consul of the Dubrovnik Republic in Algeria (1790), and a letter written by Sabato Valenzin to the Austrian authorities of Dubrovnik district (1873) (vol. D, XXIII).

The subseries consists of four types of sultans’ documents: charters (Tur. ahdname, ahitname), decrees (Tur. ferman), decrees of special importance (Tur. hatt-ı hümayun) and diplomas (Tur. berat), which were issued in the period from the middle of the 15th to the beginning of the 19th century. The documents of this subseries primarily deal with trade, shipping, customs, or the acquisition of cereals from the Ottoman Empire and other food for the needs of the Dubrovnik Republic. Documents also refer to other topics such as: land and sea bandits, espionage of the Dubrovnik Republic for the Ottomans, exchange of prisoners of war in neutral Dubrovnik, monopoly on the sale of Dubrovnik salt to Ottoman subjects, monopoly of neutral Dubrovnik ports for interstate trade, or transport of Ottoman goods and passengers by Dubrovnik ships. A fairly large number of sultans’ receipts for the tribute that the Republic paid to the Empire has also been preserved, as well as other sultans’ decrees according to which sea captains from the Republic were protected from attacks of North African corsairs in the second half of the 18th century.

An analytical inventory was made for this subseries, which indicates that only fifteen documents refer to Jews. In these documents Jews are referred to as: Ottoman customs officers (vol. 5, no. 214; vol. 8, no. 394; vol. 10, no. 459), as both debtors and creditors (vol. 10, no. 484; vol. 45, no. 1586; vol. 46, no. 1629) and as competitors to Dubrovnik merchants (vol. 59, no. 1952). In the first half of the 17th century and in the 20s of the 18th century, Dubrovnik government complained at the Porte about the Jews who damaged the house in Edirne owned by the Republic. When the house burned down, the Jews occupied the land on which it was located. In four of his decrees, the sultan demanded that the Jews should compensate the damage to Ragusans and return the land they had occupied (vol. 16, no. 799; vol. 20, no. 952; vol. 22, no. 1050; vol. 37, no. 1457). The Sultan Selim II asked the authorities of the Republic to organize a safe trip to Venice for the Jew Menachem and his servant (vol. 6, no. 299). Trade rights and prohibitions on trade for Jewish merchants can also be found in some documents of this subseries (vol. 18, no. 886; vol. 47, no. 1648).
