Anatolia before the rule of the Ottomans

The origins of the Ottomans can be traced back to the late 11th century when a few small Muslim emirates of Turkic origins and nomadic nature—called Beyliks—started to be founded in different parts of Anatolia

 would contest the issue for some time, the victory at Manzikert signalled the beginning of Turkic ascendancy in Anatolia. The subsequent weakening of the Byzantine Empire and the political rivalry between the Seljuq Sultanate of Rûm and the Fatimids in Egypt and southern Syria were the main factors that helped the Beyliks take advantage of the situation and unite their principalities.

Among those principalities was a tribe called Söğüt

The weakened Byzantine Empire no longer possessed the resources to defeat Murad on its own, and concerted action on the part of the Byzantines, often divided by civil war, was impossible.

, bringing him into direct contact with Bulgaria and the southeastern Serbian lands ruled by Uglješa. Uglješa, the most powerful Serb regional ruler, unsuccessfully attempted to forge an anti-Ottoman alliance of Balkan states in 1371. Byzantium, vulnerable to the Turks because of its food supply situation, refused to cooperate.

 and the Serbs numbering some 70,000 men under the command of the Serbian king of Prilep Vukašin Mrnjavčević and his brother despot Uglješa. Despot Uglješa wanted to make a surprise attack in their capital city, Edirne, while Murad I was in Asia Minor. The Ottoman army was much smaller, but due to superior tactics (night raid on the allied camp), Şâhin Paşa was able to defeat the Christian army and kill King Vukašin and despot Uglješa. Macedonia and parts of Greece fell under Ottoman power after this battle. Both Uglješa and Vukašin perished in the carnage. So overwhelming was the Ottoman victory that the Turks referred to the battle as the Rout (or Destruction) of the Serbs.

What little unity Serbia possessed collapsed after the catastrophe at Ormenion. Uroš died before the year was out, ending the Nemanja dynasty, and large areas of central Serbia broke away as independent principalities, reducing it to half of its former size. No future ruler ever again officially held the office of car, and no single bojar enjoyed enough power or respect to gain recognition as a unifying leader. Vukasin's son Marko, who survived the slaughter, proclaimed himself Serbian "king" (kralj) but was unable to make good on his claim outside of his lands around Prilep

 in central Macedonia. Serbia slipped into accelerated fragmentation and internecine warfare among the proliferating regional princes.

In the aftermath of the Ormenion battle, Ottoman raids into Serbia and Bulgaria intensified. The enormity of the victory and the incessant raids into his lands convinced Turnovo Bulgarian Tsar Shishman of the necessity for coming to terms with the Ottomans. By 1376 at the latest, Shishman accepted vassal status under Murad and sent his sister as the sultan's "wife" to the harem at Edirne. The arrangement did not prevent Ottoman raiders from continuing to plunder inside of Shishman's borders. As for Byzantium, Emperor John V definitively accepted Ottoman vassalage soon after the battle, opening the door to Murad's direct interference in Byzantine domestic politics.

Philadelphia, 1378

The Bulgarians and Serbs enjoyed a brief respite during the 1370s and into the 1380s when matters in Anatolia and increased meddling in Byzantium's political affairs kept Murad preoccupied. In Serbia, the lull permitted the northern Serb ‘’bojar’’ Prince Lazar Hrebeljanovic (1371-89), with the support of powerful Macedonian and Montenegrin nobles and the backing of the Serbian Orthodox Patriarchate of Pec, to consolidate control over much of the core Serbian lands. Most of the Serb regional rulers in Macedonia, including Marko, accepted vassalage under Murad to preserve their positions, and many of them led Serb forces in the sultan's army operating in Anatolia against his Turkish rivals.

Saurian Field, 1385

Savra field battle was fought on 18 September 1385 between Ottoman and Serbian forces. The Ottomans were victorious and most of the local Serbian and Albanian lords became vassals.

Plocnik, 1386

Murad captured Nis in 1386, perhaps forcing Lazar of Serbia to accept Ottoman vassalage soon afterward. While he pushed deeper into the north—central Balkans, Murad also had forces moving west along the ‘’Via Ingatia’’ into Macedonia, forcing vassal status on regional rulers who until that time had escaped that fate. One contingent reached the Albanian Adriatic coast in 1385. Another took and occupied Thessaloniki in 1387. The danger to the continued independence of the Balkan Christian states grew alarmingly apparent.

When Anatolian affairs forced Murad to leave the Balkans in 1387, his Serbian and Bulgarian vassals attempted to sever their ties to him. Lazar formed a coalition with Tvrtko I of Bosnia and Stratsimir of Vidin. After he refused an Ottoman demand that he live up to his vassal obligations, troops were dispatched against him. Lazar and Tvrtko met the Turks and defeated them at Plocnik, west of Nis. The victory by his fellow Christian princes encouraged Shishman to shed Ottoman vassalage and reassert Bulgarian independence.

Bileća, 1388

Murad returned from Anatolia in 1388 and launched a lightning campaign against the Bulgarian rulers Shishman and Stratsimir, who swiftly were forced into vassal submission. He then demanded that Lazar proclaim his vassalage and pay tribute. Confident because of the victory at Plocnik, the Serbian prince refused and turned to Tvrtko of Bosnia and Vuk Brankovic, his son-in-law and independent ruler of northern Macedonia and Kosovo, for aid against the certain Ottoman retaliatory offensive.

Kosovo, 1389

Murad's expected assault materialized in 1389. The sultan personally led the largest Ottoman force mustered in the Balkans to that time, which included Christian contingents furnished by Bulgarian, Serbian, Albanian, and Macedonian vassals, Kralj Marko of Prilep among them. Likewise, Lazar himself commanded the coalition army composed of troops of his loyal Serb bajars, Brankovic's Kosovar and northern Macedonian forces, a Bosnian contingent, and some allied Hungarian and Albanian units. The protagonists met at Kosovo Polje (the "Field of the Blackbirds") on 15 June 1389.

The battle of Kosovo was an important victory for the Ottomans. While the Ottomans could count on an Anatolian reserve to replace their losses, the Serbs, who had mustered all of their able-bodied troops for the battle, were left irreparably weakened. In the three years following the battle, Ottoman raids forced one militarily ineffective Serb regional ruler after another to accept vassalage to Bayezid. Lazar's young and weak successor Stefan Lazarevic (1389–1427) concluded a vassal agreement with Bayezid in 1390 to counter Hungarian moves into northern Serbia, while Vuk Brankovic, the last independent Serb prince, held out until 1392.

Beyazid I and the western expansion

Beyazid I succeeded to the sultanship upon the assassination of his father Murad. In a rage over the attack, he ordered all Serbian captives killed; Beyazid became known as Yıldırım, the lightning bolt, for his temperament.

Bayezid, "the Thunderbolt", lost little time in expanding Ottoman Balkan conquests. He followed up on his victory by raiding throughout Serbia and southern Albania, forcing most of the local princes into vassalage. Both to secure the southern stretch of the Vardar-Morava highway and to establish a firm base for permanent expansion westward to the Adriatic coast, Bayezid settled large numbers of ‘’yürüks’’ along the Vardar River valley in Macedonia.

The appearance of Turk raiders at Hungary's southern borders awakened Hungarian King Sigismund of Luxemburg (1387–1437) to the danger that the Ottomans posed to his kingdom, and he sought out Balkan allies for a new anti-Ottoman coalition.

By early 1393 Turnovo Bulgaria's Ivan Shishman, hoping to throw off his onerous vassalage, was in secret negotiations with Sigismund, along with Wallachian Voievod Mircea the Old (1386–1418) and, possibly, Vidin

's Ivan Stratsimir. Bayezid got wind of the talks and launched a devastating campaign against Shishman. Turnovo was captured after a lengthy siege, and Shishman fled to Nikopol

. After that town fell to Bayezid, Shishman was captured and beheaded. All of his lands were annexed outright by the sultan, and Stratsimir, whose Vidin holdings had escaped Bayezid's wrath, was forced to reaffirm his vassalage.

Having dealt harshly and effectively with his disloyal Bulgarian vassals, Bayezid then turned his attention south to Thessaly and the Morea, whose Greek lords had accepted Ottoman vassalage in the 1380s. Their incessant bickering among themselves, especially those of the Greek Morean magnates, required Bayezid's intervention. He summoned a meeting of all his Balkan vassals at Serres

 in 1394 to settle these and other outstanding matters. Among the sultan's attending vassals were the Thessalian and Morean nobles, Byzantine Emperor Manuel II Palaiologos

 (1391–1425), and Serbian Prince Lazarevic. At the meeting, Bayezid acquired possession of all disputed territories, and all of the attendees were required to reaffirm their vassal status.

When the Moreans later reneged on their Serres agreement with Bayezid, the angered Ottoman ruler blockaded the Morean despot's imperial brother Manuel II in Constantinople and then marched southward and annexed Thessaly. The Duchy of Athens

 accepted Ottoman overlordship when Turkish forces appeared on its border. Although a massive Ottoman punitive raid into the Peloponnese in 1395 netted much booty, events in the Balkans’ northeast saved Morea from further direct attack at the time.

While Bayezid was occupied in Greece, Mircea of Wallachia conducted a series of raids across the Danube into Ottoman territory. In retaliation, Bayezid's forces, which included Serb vassal troops led by Lazarevic and Kralj Marko, struck into Wallachia in 1395 but were defeated at Rovine

The Battle of Rovine took place on 17 May 1395 between the Wallachian army led by Voivod Mircea cel Bătrân against the Ottoman invasion led by sultan Bayezid I. The Ottoman army, numbering approximately 40,000 men, faced the much smaller Wallachian army, which was about 10,000 men...

, where Marko was killed. The victory saved Wallachia from Turkish occupation, but Mircea accepted vassalage under Bayezid to avert further Ottoman intervention. The sultan took consolation for his less than victorious efforts in annexing Dobrudzha and in supporting a pretender, Vlad I (1395–97), to the Wallachian throne. Two years of civil war ensued before Mircea regained complete control of the principality.

Nicopolis

In 1396 Hungarian King Sigismund finally pulled together a crusade against the Ottomans. The crusader army was composed primarily of Hungarian and French knights, but included some Wallachian troops. Though nominally led by Sigismund, it lacked command cohesion. The crusaders crossed the Danube, marched through Vidin, and arrived at Nikopol, where they met the Turks. The headstrong French knights refused to follow Sigismund's battle plans, resulting in their crushing defeat

. Because Stratsimir had permitted the crusaders to pass through Vidin, Bayezid invaded his lands, took him prisoner, and annexed his territories. With Vidin's fall, Bulgaria ceased to exist, becoming the first major Balkan Christian state to disappear completely by direct Ottoman conquest.

Following Nikopol, Bayezid contented himself with raiding Hungary, Wallachia, and Bosnia. He conquered most of Albania and forced the remaining northern Albanian lords into vassalage. A new, halfhearted siege of Constantinople was undertaken but lifted in 1397 after Emperor Manuel II, Bayezid's vassal, agreed that the sultan should confirm all future Byzantine emperors. Soon thereafter Bayezid was called back to Anatolia to deal with continuing problems with the Ottomans’ Turkish rivals and never returned to the Balkans.

Ankara, 1402

Bayezid took with him an army composed primarily of Balkan vassal troops, including Serbs led by Lazarevic. He soon faced an invasion of Anatolia by the Central Asian ruler Timur. Around 1400, Timur entered the Middle East. Timur Lenk pillaged a few villages in eastern Anatolia and commenced the conflict with the Ottoman Empire. In August, 1400, Timur and his horde burned the town of Sivas to the ground and advanced into the mainland. Their armies met outside of Ankara, Battle of Ankara

In 1410 he was defeated and killed by his brother Musa, who won the Ottoman Balkans with the support of Byzantine Emperor Manuel II, Serbian Despot Stefan Lazarevic, Wallachian Voievod Mircea, and the two last Bulgarian rulers’ sons. Musa then was confronted for sole control of the Ottoman throne by his younger brother Mehmed, who had freed himself of Mongol vassalage and held Ottoman Anatolia.

Concerned over the growing independence of his Balkan Christian vassals, Musa turned on them. Unfortunately, he alienated the Islamic bureaucratic and commercial classes in his Balkan lands by continually favoring the lower social elements to gain wide popular support. Alarmed, the Balkan Christian vassal rulers turned to Mehmed, as did the chief Ottoman military, religious, and commercial leaders. In 1412 Mehmed invaded the Balkans, took Sofia and Nis, and joined forces with Lazarevicys Serbs. The following year Mehmed decisively defeated Musa outside of Sofia. Musa was killed, and Mehmed I

Hungary retained territorial ambitions in the Balkans, and Venice held numerous Balkan coastal possessions. Prior to Bayezid's death, Ottoman control of the Balkans appeared a certainty. At the end of the Interregnum, that certainty seemed open to question.

 proved his skills both on the military and the political front and was soon accepted by the noble class of the Ottoman court.

Older and a good deal wiser, he made capturing Constantinople his first priority, believing that it would solidify his power over the high military and administrative officials who had caused him such problems during his earlier reign. Good reasons underlay his decision. So long as Constantinople remained in Christian hands, his enemies could use it as either a potential base for splitting the empire at its center or as an excuse for the Christian West's continued military efforts. Constantinople's location also made it the natural "middleman" center for both land and sea trade between the eastern Mediterranean and central Asia, possession of which would ensure immense wealth. Just as important, Constantinople was a fabled imperial city, and its capture and possession would bestow untold prestige on its conqueror, who would be seen by Muslims as a hero and by Muslims and Christians alike as a great and powerful emperor.

Mehmed spent two years preparing for his attempt on the Byzantine capital. He built a navy to cut the city off from outside help by sea; he purchased an arsenal of large cannons from the Hungarian gunsmith Urban; he sealed the Bosphorus north of the city by erecting a powerful fortress on its European shore to prevent succor arriving from the Black Sea; and he meticulously concentrated in Thrace every available military unit in his lands. A trade agreement with Venice prevented the Venetians from intervening on behalf of the Byzantines, and the rest of Western Europe unwittingly cooperated with Mehmed's plans by being totally absorbed in internecine wars and political rivalries.

 for the first time since 751. Justinian's cathedral of Hagia Sophia was converted into an imperial mosque, as eventually were numerous other churches and monasteries. The rights of non-Muslim inhabitants were protected to ensure continuity and stability for commercial activities. Never fully recovered from the sack of 1204, and suffering from Byzantium's two centuries of near poverty, Constantinople by the time of Mehmed's conquest was but a hollow shell of its former self. Its population had dwindled, and much property was either abandoned or in a state of disrepair. The sultan immediately began to repopulate the newly renamed city. Civic and private properties were offered to the public to entice much-needed skilled artisans, craftsmen, and traders of all religions and ethnicities back to the city. Newly conquered Constantinople rapidly grew into a multiethnic, multicultured, and bustling economic, political, and cultural center for the Ottoman state, whose distant frontiers guaranteed it peace, security, and prosperity.

Belgrade, 1456

Mehmed, now known as "the Conqueror", determined to centralize his empire. In the Balkans, he decided to eradicate the last vestiges of Byzantium in Morea and to eliminate the surviving Christian vassal princes elsewhere. In 1454 he commenced a series of military campaigns, lasting until 1463, aimed at establishing a solid military defense line along the Danube and the Adriatic against Hungary and Venice.

Serbia ranked first on Mehmed's agenda. After two years of campaigning, Mehmed acquired southern Serbia and the lucrative silver and gold mines of Novo Brdo. In 1456 a cowed Brankovié permitted Mehmed to march through his remaining lands and besiege the Hungarians in Belgrade. Mehmed's efforts to take the fortress city were checked by Hunyadi, who arrived with reinforcements at the last moment and forced Mehmed to retire. Soon afterward Brankovic died, and the usual Serbian succession problems reemerged. In the anarchy that erupted, Mehmed laid claim to the Serbian throne, based on his having a Serb stepmother, but continuing problems with Skanderbeg in Albania and the Byzantine despots in Morea prevented him from acting immediately on his claim.

The wily Albanian commander attempted to drive out the Ottoman garrisons stationed in Albania, and Mehmed dispatched a number of expeditions to push Skanderbeg's forces back into the mountains. While the sultan was thus occupied, the Morean despots, the brothers Demetrios Palaiologos of Mystras (1449–60) and Thomas Palaiologos of Patras (1449–60), fell into civil war. Demetrios was well disposed toward the Ottomans, while Thomas sought help from the pope and other Western rulers against both his brother and the Turks. Their conflict reduced Morea to anarchy.

Mehmed arrived in Greece in 1458 and annexed its northern regions. By early 1459 Athens was taken, and a year later Thomas was forced to flee Patras. Demetrios then handed over Mystras to Mehmed. With the fall of Morea in 1460, the Byzantine Empire ceased to exist. All of Greece, with the exception of the Venetian-controlled ports of Methoni, Koroni

, lay under direct Ottoman authority.

A year before Morea fell, Mehmed had moved swiftly north and invaded Serbia one final time, making good on his claim to the Serbian throne. What lands that remained of vassal Serbia were occupied outright by Mehmed's forces. At the time Hungarian King Matthias Corvinus (1458–90), Hunyadi's son, was more interested in Central European affairs than in the Balkans, so he gave scant attention to events occurring south of his border. The Serbs’ last stand took place at Smederevo, which fell to Mehmed in June 1459. With its capture, the Serbian state completely disappeared. Only the city of Belgrade, still held by the Hungarians, lay beyond Mehmed"s control south of the Danube.

Following the conquests of Serbia and Greece, Skanderbeg's Albania continued to cause Mehmed problems. A truce was arranged with the troublesome Albanian in 1461 in time for Mehmed to deal with a Wallachian incursion into Bulgaria led by Voievod Vlad III Dracula

 out. Instead of annexing the principality, he merely reduced it to vassal status under a new voievod.

Alarmed by the Ottomans’ consolidation of their Balkan holdings and expansion along the Adriatic coast, Venice encouraged the redoubtable Skanderbeg to break his truce with Mehmed in 1462. Bosnian King-Ban Stefan Tomasevic (1461–65), heartened by Skanderbegs renewed activities, renounced Ottoman suzerainty and accepted Hungarian protection. Herceg Stefan Vukcic (1455–66), lord of Hercegovina, which had separated from Bosnia in the 1440s, followed suit. Their actions elicited Mehmed's quick response. He invaded Albania in 1465 and forced Skanderbeg to sign a new truce. Next, he turned north and overran both Bosnia and Hercegovina. Bosnia was conquered outright but Hercegovina, with Hungarian assistance, staved off a similar fate for another eighteen years, until finally falling to the Turks in 1481.

One territory closely linked to the Serbs was Montenegro, a mountainous region to Serbia's southwest with a small coastline on the Adriatic. In the early 1450s it achieved independence from Brankovic's Serbia under the leadership of Stefan Crnojevic (ca. 1451-65), who enjoyed Venetian support. Assisted by his state's rugged terrain, Crnojevic turned back the raiders Mehmed sent against him during the 1450s, although a number of his regional tribal chieftains accepted Ottoman vassalage. After his death, his son Ivan Crnojevic (1465–90) swore vassalage to Mehmed in 1471, but that did not prevent the Ottomans from occupying large portions of his lands. When Ivan reneged on his tribute payments, Mehmed included an invasion of Montenegro

 took advantage. As the state weakened, Voievod Peter Aron (1455–57) accepted Ottoman suzerainty and agreed to pay tribute, but, given Moldavia's distance from
Ottoman borders, his acts were more symbolic than concrete.

Stefan the Great initially used the Ottoman vassalage inherited from his father as a tool against Hungary, Moldavia's traditional enemy. An exceptional military commander and organizer, Stefan captured the Danube commercial city of Kilia from Wallachia in 1465 and defeated a Hungarian invasion of his state two years later. As his successes both on the battlefield and in imposing his authority within Moldavia grew, Stefan ceased paying the annual tribute to the Ottomans, and his relationship with Mehmed II deteriorated. He invaded Wallachia in 1474 and ousted its prince, who was Mehmed's abject vassal. In response, Mehmed demanded that Stefan resume his tribute payments and turn over the city of Kilia as well. Stefan refused and soundly repulsed Mehmed's subsequent punitive invasion of Moldavia in early 1475.

Breadfield, 1479

The victorious zmievad realized that Mehmed would seek to avenge the defeat, so Stefan sought Hungarian aid by becoming Matthias Corvinus°s vassal. Mehmed personally led an invasion of Moldavia in 1476, and his forces plundered the country up to Suceava, Stefan's capital. Lack of provisions and an outbreak of cholera among the Ottoman troops, however, forced Mehmed to retire, and Stefan went on the offensive. He pushed into Wallachia and spent the next nine years fighting a heroic border war with the Ottomans. Stefan's efforts were the primary reason that the two Romanian Principalities maintained their independence and did not suffer the fate of the other Ottoman vassal states south of the Danube.

In 1480 Mehmed dispatched an army to Italy that marched against Rome to punish the pope for supporting Venice and assorted anti-Ottoman coalitions. The invasion force captured Otranto and was advancing on Rome when news of the sultan's death in 1481 stopped their advance, sparing Rome almost certain capture.

When Mehmed died, the conquest of the Balkans essentially was complete.
