Medieval Serbian army

The Serbian army was feudal in nature, though its system of military landholding was inherited from the Byzantine pronoia rather than the Western European fief. The pronoia itself - hereditary by some accounts, non-hereditary by others - is only first recorded in Serbia under that name in 1299 (the Serbs spelt it pronija, or pronya, and called its holder a pronijar), but even from as early as Stefan Nemanja reign (1186–96) every able-bodied man possessing a bashtina (a grant of hereditary freehold land, the holder being called a bashtinik or voynici) had been obliged to attend the army whenever required, only monastic tenants being exempted in exchange for performing part-time garrison duties in local fortresses and fortified monasteries. The building and maintenance (gradozadanje) of such fortresses, and equally the maintenance of their permanent garrisons (gradobljudenlje) was an additional aspect of the feudal responsibilities of the population of each Župa (district), who were also responsible for guarding their own frontier. The holders of both bashtinas and pronijas constituted the nobility (though many of the former were only upper-class peasants), and these were the principal native element of every Serbian army, serving as heavy cavalry (the proniiars) and infantry (the voynici), In fact most armies included only the nobility (the vlastelini, or 'holders of power') and their retinues, maintained at their own expense, but in times of emergency the arriere-ban, called the Zamanitchka Voyska ('All Together'), would be summoned. As elsewhere, this comprised all the nobility and every able-bodied freeman.

In border regions all land-grants appear to have been called krayina and their holders vlastele krayishnik ('border lords'), whose duty it was to guard the frontier. Dušan's Code of 1349 (the Zakonik, extended and completed in 1354) actually states that any damage inflicted by an invading army had to be compensated for by the border-lord through whose lands the enemy had entered, another article stating that similar pillaging committed by brigands had to be repaid seven-fold. The Byzantine chronicler Gregoras, as ambassador for Andronikos III to Emperor Dusan, encountered some krayishnici (men of a border- lord) on crossing the frontier. He wrote: 'When we passed the Struma River ... and came into thick woods, we were suddenly surrounded by men clad in black woolen garments, who darted forth from behind trees and rocks like devils out of the earth. They wore no heavy armor, being armed only with spears, battle-axes, and bows and arrows.

From the 11th century on the commander-in-chief of the army was the king (kral), a veliki vojevoda or 'high military chief, equivalent to the Byzantine Grand Domestic, being appointed in his absence. However, since any call to arms had to be approved by the Sabor (the National Assembly) the king actually had limited military power, in effect being no more than a glorified Grand Župan, or elected tribal leader. Although Dušan stripped the Sabor of much of its power, the crown's dependence on a permanent nucleus of mercenaries that was not subject to the assembly's whims had by then already evolved, constituting the core of all Serbian armies throughout this period. Under Stephen Uroš II Milutin (1282-1321) these mercenaries included such diverse elements as Cumans; Anatolian Turks (some 1,500 were employed in 1311 from amongst those who had been allied to the Catalans in Thrace and Macedonia); Tartars from South Russia; and Christian Ossetians (Jasi in Serbian and Russian sources) from the Caucasus. However, it was Western European style heavy cavalry which soon came to predominate. As early as 1304 a certain Francisco de Salomone is mentioned in an inscription in Trevise as having distinguished himself in the service of 'Orosius, rex Rascie' (i. e. Uroš, king of Serbia). Mercenaries in Stephen Uroš III's army that defeated the Bulgarians at Battle of Velbazhd in 1330 were 1,500 Aragonese, Spaniards, and Germans, and it was the latter who seem to have predominated during Dušan reign. The papal legate to his court reported seeing 300 German mercenaries there under the knight Palman Bracht, who held the rank of capitaneus. In addition we know that the Serbian troops supplied to the Byzantine Emperor, John VI Kantakouzenos, in 1342-43 were Germans, and that the troops garrisoning Beroia in Macedonia in 1341-50 were German mercenaries too. Even at the Battle of Kosovo in 1389 it is significant that many of Lazar men were German and Hungarian mercenaries according to a Florentine account, while a mid-15th century Ottoman source reports that his army included Wallachians, Hungarians, Bohemians, Albanians, Bulgarians and Franks, doubtless chiefly mercenaries. Another says he employed many mercenaries from among the Serbians themselves as well as the Hungarians, Bosnians and Albanians. Serbian documents indicate that as well as Germans the other predominant European mercenary elements comprised Spaniards (possibly as many as 1,300-strong at one point) plus Hungarians, Frenchmen, Italians and Swiss. One prominent name to appear in their ranks was that of Philippe de Mézières, in later life Chancellor of Cyprus and one of the last protagonists of the Crusade. Inevitably, in the 15th century Ottoman auxiliaries were also used, for example by Vuk Lazarević against Stephen, 1409-13. In addition to the king or despot, the larger cities also employed some mercenaries of their own to back up their militia.

When the Ottoman hold on Serbia weakened after the Battle of Ankara, Stefan Lazarević took advantage of the situation to establish his independence from the Turks. Recognizing the king of Hungary as his overlord he built up a small regular army, on the basis of a newly imposed levy known as the vojstatik, which was stationed in the country's 11 major fortresses as well as several of its small walled towns. This army included many Hungarians and was well equipped with cannon and handguns; for example, there were 2 cannons in the fort guarding the large silver mine at Srebrnica in 1425, and in Belgrade, Lazarević capital, there was a large bombard (called Humka, meaning 'Knoll') captured from the Bosnians the same year. In 1455 there were as many as 3 large cannon, 5 other guns and 55 handguns in the fort guarding the great silver mine at Novo Brdo.

Serbian armies were composed of lance-armed light and heavy cavalry, plus infantry (armed with spears, axes, and above all bows and, later, crossbows) and a baggage-train (komora) manned by shepherds ("Vlachs"). Most of their armies tended to be small because of the difficulties involved in supplying them in the field, and on the whole they could probably raise only about 12,000 men in the late 14th-century, the army at the Battle of Kosovo probably numbering at most 20-25,000 men including allied contingents. The majority were heavy cavalry. Emperor Stefan Dušan was said to have raised around 80,000 men for the invasion of Bosnia in 1350 although the largest Serbian army on record in this period was that raised by Dušan in 1355 for his proposed attack on Constantinople, which numbered 85,000 men according to later Ragusan chronicles.

After the Battle of Maritsa in 1371, Ottoman suzerainty was accepted by the Serbian rulers in Macedonia: King Marko (Vukašin Mrnjavčević's son), Konstantin Dragaš, and Radoslav Hlapen.[13] By 1388, Djuradj Stracimirović Balšić, the lord of Zeta, also became an Ottoman vassal.[14] Stefan Lazarević and Vuk Branković accepted Ottoman suzerainty in 1390 and 1392, respectively.[9] Stefan Lazarević ceased to be an Ottoman vassal and ally in 1402, when he became a despot and created the Serbian Despotate.[11] According to Serbian historiography, Stefan from 1390 on, was obliged to pay an annual tribute of 1,000 lbs of gold and to provide the sultan with a contingent of 1,000 cavalry when called upon. Finlay and Creasy, however, maintained that it was the treaty of 1376 that first imposed this obligation, while Gibbons says 1386; certainly there were Serbs as well as Bulgarians and Byzantines in the Ottoman army that fought against the Karamanli Turks in Anatolia in 1387 (the Serbs being promised booty in return for their services). Finlay says in one of his books that Sultan Beyazid actually demanded the service of the same number of Serbians as the Byzantines had called for after Manuel's subjugation of Serbia in 1150, i.e. 2,000 to armies serving in Europe and 500 to armies serving in Asia; but in another book he says that the figure was only 'subsequently increased to 2,000 men' when Beyazid was gathering his forces to confront Tamerlane in 1402. Bertrandon de la Brocquière, in his 'Travels' of 1432-33, recorded of the despot of Serbia that 'every time the sultan sends him his orders, he is obliged to furnish him with 800 or 1,000 horse, under the command of his second son.' Elsewhere he adds how he had heard that 'in the most recent army [supplied to the sultan] from Greece, there were 3,000 Serbian horse, which the despot of the province had sent under the command of one of his sons. It was with great regret that these people came to serve him, but they dared not refuse.' Konstantin Mihailović reports that when the treaty with Serbia was renewed under Mehmed II the obligatory tribute was set at 1,500 lbs of gold and a contingent of 1,500 cavalry.

Amongst the battles in which Serbs fought for their Ottoman allies were Battle of Rovine, against the Wallachians and Bulgarians, in 1395; Battle of Nicopolis in 1396, where apparently their contingent comprised 5,000 heavy cavalry; and Battle of Ankara in 1402, where Doukas says there were 5,000 "encased in black armor" and Chalkokondyles that there were an unlikely 10,000 (though the Ottoman chronicler al-Anwari says that there were 10,000 Serbs and Wallachians altogether). George Branković even supplied an unwilling contingent of 1,500 cavalry under voivode Jakša according to Konstantin Mihailović, for the final siege of Constantinople in 1453, plus some silver-miners from Novo Brdo whom Sultan Mehmed employed as sappers. On August 11, 1473, the army that marched against Uzun Hasan which resulted in an Ottoman victory in The battle of Otlukbeli included many Christians - Greeks, Albanians and Serbians, in their number.

Prior to the 14th century the army consisted of classic European-style noble cavalry armed with bows and lances (replaced with crossbows in the 14th century) and infantry armed with spears, javelins and bows.

Serbia had adopted gunpowder artillery from the Republic of Ragusa, where a centre for the manufacture of wrought-iron cannon existed by 1363. The first gun foundry in the Balkans, casting bronze cannons, was also established at Ragusa (Dubrovnik), in 1410. Neighbouring Bosnia had cannon by 1380, and they were in use in Serbia by 1382–86 at the very latest, probably served and certainly made by Ragusan engineers. In fact, Ragusan chronicler Mavro Orbini (1563–1614) claims that knez Lazar Hrebeljanović used guns against župan Nikola Altomanović even as early as 1373. Guns were apparently employed in the field by the Serbians as early as 1389 at the Battle of Kosovo, being clearly mentioned in one later Ottoman chronicle (Mehmed Neşrî) and alluded to in a contemporary Serbian source which says that 'fiery explosions thundered, the earth roared greatly, and the air echoed and blew around like dark smoke'; we know too that King Tvrtko of Bosnia (1353–91) brought one gun, a gift of the Italians, with him to the battle. The Serbian contingent in the Ottoman army defeated at Ankara in 1402 also had artillery, but as at Kosovo it failed to affect the outcome, probably for the same reasons on both occasions - i.e. the guns were too small to be effective in order that they might be maneuverable on the battlefield. In siege work trebuchets and ballistae remained in service alongside gunpowder artillery for a long time.

In addition to her land forces, Serbia occasionally also had a very small fleet, provided by the communes of Dulcigno (modern Ulcinj), Budua (Budva) and Cattaro (Kotor), sometimes by Ragusa (in exchange for a year's tax-exemption), and briefly by Venice (which provided 4 new galleys, the galee domini imperatoris, in 1350, the subsequent fate of which is unknown). King Tvrtko of Bosnia too later constructed his own small fleet, with a Venetian as its admiral, and was similarly given a galley by Venice, this time fitted with a cannon.
