Vassal and tributary states of the Ottoman Empire



The Ottoman Empire had a number of tributary and vassal states throughout its history. Its tributary states would regularly send tribute to the Ottoman Empire, which was understood by both states as also being a token of submission. In exchange for certain privileges, its vassal states were obligated to render support to the Ottoman Empire when called upon to do so. Some of its vassal states were also tributary states. These client states, many of which could be described by modern terms such as satellite states or puppet states, were usually on the periphery of the Ottoman Empire under suzerainty of the Sublime Porte, over which direct control was not established, for various reasons.

Functions
Ottomans first demanded only a small yearly tribute from vassal princes, as a token of their submission. They later demanded that a vassal prince's son should be held as hostage, that the prince should come to the Palace once a year and swear allegiance, and that he should send auxiliary troops on the sultan's campaigns. Vassal princes were required to treat the sultan's friends and enemies as their own. If the vassal failed in these duties, his lands would be declared as darülharb (lit. territory of war) open to the raids of the Ghazis.

Forms

 * Some states within the eyalet system included sancakbeys who were local to their sanjak or who inherited their position (e.g., Samtskhe, some Kurdish sanjaks), areas that were permitted to elect their own leaders (e.g., areas of Albania, Epirus, and Morea (Mani Peninsula) was nominally a part of Aegean Islands Province but Maniot beys were tributary vassals of the Porte, or de facto independent eyalets (e.g., the Barbaresque 'regencies' Algiers, Tunisia, Tripolitania in the Maghreb, and later the Khedivate of Egypt).
 * Outside the eyalet system were states such as Moldavia, Wallachia and Transylvania which paid tribute to the Ottomans and over which the Porte had the right to nominate or depose the ruler, garrison rights, and foreign policy control. They were considered by the Ottomans as part of Dar al-'Ahd, thus they were allowed to preserve their self-rule, and were not under Islamic law, like the empire proper; Ottoman subjects, or Muslims for that matter, were not allowed to settle the land permanently or to build mosques.
 * Some states such as Ragusa paid tribute for the entirety of their territory and recognized Ottoman suzerainty.
 * Others, such as the Sharif of Mecca, recognized Ottoman suzerainty but were subsidized by the Porte. The Ottomans were also expected to protect the Sharifate militarily – as suzerains over Mecca and Medina, the Ottoman sultans were meant to ensure the protection of the Hajj and Umrah pilgrimages and safe passage of pilgrims. The Amir al-hajj was a military officer appointed by the Sultanate to ensure this.
 * During the nineteenth century, as Ottoman territory receded, several breakaway states from the Ottoman Empire had the status of vassal states (e.g. they paid tribute to the Ottoman Empire), before gaining complete independence. They were however de facto independent, including having their own foreign policy and their own independent military. This was the case with the principalities of Serbia, Romania and Bulgaria.
 * Some states paid tribute for possessions that were legally bound to the Ottoman Empire but not possessed by the Ottomans such as the Habsburgs for parts of Royal Hungary or Venice for Zante.

There were also secondary vassals such as the Nogai Horde and the Circassians who were (at least nominally) vassals of the khans of Crimea, or some Berbers and Arabs who paid tribute to the North African beylerbeyis, who were in turn Ottoman vassals themselves.
