Mehmed I (1379 – 26 May 1421), also known as Mehmed Çelebi (Ottoman Turkish: چلبی محمد‎, "the noble-born") or Kirişçi (from Greek Kyritzes. "lord's son"), was the Ottoman Sultan from 1413 to 1421. The fourth son of Sultan Bayezid I and Devlet Hatun, he fought with his brothers over control of the Ottoman realm in the Ottoman Interregnum (1402-1413). Starting from the province of Rûm he managed to bring first Anatolia and then the European territories (Rumelia) under his control, reuniting the Ottoman state by 1413, and ruling it until his death in 1421.

Early life

Mehmed was born in 1379 as the fourth son of Sultan Bayezid I (r. 1389-1402) and one of his consorts, the slave girl Devlet Hatun. Following Ottoman custom, when he reached adolescence in 1399, he was sent to gain experience as provincial governor over the Rûm Eyalet (central northern Anatolia), recently conquered from its Eretnid rulers.

On 20 July 1402, his father Bayezid was defeated in the Battle of Ankara by the Turko-Mongol conqueror and ruler Timur. The brothers (with the exception of Mustafa, who was captured and taken along with Bayezid to Samarkand) were rescued from the battlefield, Mehmed being saved by Bayezid Pasha, who took him to his hometown of Amasya. Mehmed later made Bayezid Pasha his grand vizier (1413-1421).

The early Ottoman Empire had no regulated succession, and according to Turkish tradition, every son could succeed his father. Of Mehmed's brothers, the eldest, Ertuğrul, had died in 1400, while the next in line, Mustafa, was a prisoner of Timur. Leaving aside the underage siblings, this left four princes — Mehmed, Süleyman, İsa, and Musa, to contend over control of the remaining Ottoman territories in the civil war known as the “Ottoman Interregnum.” In modern historiography, these princes are usually called by the title Çelebi, but in contemporary sources, the title is reserved for Mehmed and Musa. The Byzantine sources translated the title as Kyritzes (Κυριτζής), which was in turn adopted into Turkish as kirişçi, sometimes misinterpreted as güreşçi, "the wrestler".

After winning the Interregnum, Mehmed crowned himself sultan in the Thracian city of Edirne that lay in the European part of the empire (the area dividing the Anatolian and European sides of the empire, Constantinople and the surrounding region, was still held by the Byzantine Empire), becoming Mehmed I. He consolidated his power, made Edirne the most important of the dual capitals, and conquered parts of Albania, the Jandarid emirate, and the Armenian Kingdom of Cilicia from the Mamelukes. Taking his many achievements into consideration, Mehmed is widely known as the “second founder” of the Ottoman Sultanate.

Soon after Mehmed began his reign, his brother Mustafa Çelebi, who had originally been captured along with their father Bayezid I during the Battle of Ankara and held captive in Samarkand, hiding in Anatolia during the Interregnum, reemerged and asked Mehmed to partition the empire with him. Mehmed refused and met Mustafa's forces in battle, easily defeating them. Mustafa escaped to the Byzantine city of Thessaloniki, but after an agreement with Mehmed, the Byzantine emperor Manuel II Palaiologos exiled Mustafa to the island of Lemnos.

However, Mehmed still faced some problems, first being the problem of his nephew Orhan, who Mehmed perceived as a threat to his rule, much like his late brothers had been. There was allegedly a plot involving him by Manuel II Palaiologos, who tried to use Orhan against Sultan Mehmed; however, the sultan found out about the plot and had Orhan blinded for betrayal, according to a common Byzantine practice.

Furthermore, as a result of the Battle of Ankara and other civil wars, the population of the empire had become unstable and traumatized. A very powerful social and religious movement arose in the empire and became disruptive. The movement was led by Sheikh Bedreddin (1359-1420), a famous Muslim Sufi and charismatic theologian. He was an eminent Ulema, born of a Greek mother and a Muslim father in Simavna (Kyprinos) southwest of Edirne (formerly Adrianople). Mehmed's brother Musa had made Bedreddin his “qadi of the army,” or the supreme judge. Bedreddin created a populist religious movement in the Ottoman Sultanate, "subversive conclusions promoting the suppression of social differences between rich and poor as well as the barriers between different forms of monotheism." Successfully developing a popular social revolution and syncretism of the various religions and sects of the empire, Bedreddin's movement began in the European side of the empire and underwent further expansion in western Anatolia.

In 1416, Sheikh Bedreddin started his rebellion against the throne. After a four-year struggle, he was finally captured by Mehmed's grand vizier Bayezid Pasha and hanged in the city of Serres, a city in modern-day Greece, in 1420.


The reign of Mehmed I as sultan of the re-united empire lasted only eight years before his death, but he had also been the most powerful brother contending for the throne and de facto ruler of most of the empire for nearly the whole preceding period of 11 years of the Ottoman Interregnum that passed between his father's captivity at Ankara and his own final victory over his brother Musa Çelebi at the Battle of Çamurlu.

He was buried in Bursa, in a mausoleum erected by himself near the celebrated mosque which he built there, and which, because of its decorations of green glazed tiles, is called the Green Mosque. Mehmed I also completed another mosque in Bursa, which his grandfather Murad I had commenced but which had been neglected during the reign of Bayezid. Mehmed founded in the vicinity of his own Green Mosque and mausoleum two other characteristic institutions, one a school and one a refectory for the poor, both of which he endowed with royal munificence.

Sheikh Bedreddin

Sheikh Bedreddin (W)

Sheikh Bedreddin (1359-1420) (Ottoman Turkish: شیخ بدرالدین‎) was an influential mystic, scholar, theologian, and revolutionary. He is most well known for his role in a 1416 revolt against the Ottoman Empire, in which he and his disciples posed a serious challenge to the authority of Sultan Mehmed I and the Ottoman state. His full name was Sheikh Bedreddin Mahmud Bin Israel Bin Abdulaziz.

Early life

Many details of Bedreddin's early life are disputed, as much of it is the subject of legend and folklore. He was born in 1359 in the town of Simavna (Kyprinos), near Edirne. His father was the ghazi of the town, and his mother was the daughter of a Greek Byzantine fortress commander. Notably, Bedreddin was of mixed Muslim and Christian parentage, with a Christian mother and a Muslim father; this contributed to his syncretic religious beliefs later in life. Turkish scholar Cemal Kafadar argues that Bedreddin's ghazi roots may also have contributed to his commitment to religious coexistence.

In his youth he was a kadi to Ottoman warriors on the marches, which gave him ample experience in jurisprudence, a field of study in which he would become well-versed. Bedreddin was exposed to a variety of different cultures during his education, traveling far from his birthplace in Thrace. He studied theology in Konya, and then in Cairo, which was the capital of the Mamluk sultanate. After this, he traveled to Ardabil, in what is now Iranian Azerbaijan. Ardabil was under the control of the Timurids, and was home to the mystic Safavid order. Surrounded by mystics and far removed from the religious norms of the Ottoman Empire, Bedreddin was in an excellent place to cultivate his unconventional religious ideology. There he found an environment sympathetic to his pantheistic religious beliefs, and particularly the doctrine of “oneness of being.” This doctrine condemned oppositions such as those of religion and social class as interference in the oneness of God and the individual, and such doctrine ran contrary to increasing Ottoman efforts to establish Sunni Islam as the state religion. By adopting it, Bedreddin further established himself as a subversive.

During the Ottoman Interregnum after the defeat of sultan Bayezid I by Tamerlane in 1402, Bedreddin served as the kadiasker, or chief military judge, of the Ottoman prince Musa as Musa struggled with his brothers for control of the Ottoman sultanate. Along with the frontier bey Mihaloglu, he was a chief proponent of Musa's revolutionary regime. While kadiasker, Bedreddin gained the favor of many frontier ghazis by distributing timars among them. Through this he aided these unpaid ghazis in their struggle against centralization, a clear indication of his subversive side.

Revolt of 1416

After Musa’s defeat by Ottoman sultan Mehmed I in 1413, Bedreddin was exiled to Iznik, and his followers were dispossessed of their timars. However, he soon decided to capitalize on the climate of opposition to Mehmed I following the disorder of the still-fresh interregnum. Leaving his exile in Iznik in 1415, Bedreddin made his way to Sinop and from there across the Black Sea to Wallachia. In 1416, he raised the standard of revolt against the Ottoman state.

Most of the revolts that ensued took place in regions of Izmir, Dobrudja, and Saruhan. The majority of his followers were Turcomans. The rest included frontier ghazis, dispossessed sipahis, medrese students, and Christian peasants. The first of these rebellions was kindled in Karaburun, near Izmir. There, Borkluje Mustafa, one of Bedreddin’s foremost disciples, instigated an idealistic popular revolt by preaching the communal ownership of property and the equality of Muslims and Christians. Most those who revolted were Turkish nomads, but Borkluje’s followers also included many Christians. In total, approximately 6,000 people revolted against the Ottoman state in Karaburun. Torlak Kemal, another of Bedreddin’s followers, led another rebellion in Manisa, and Bedreddin himself was the leader of a revolt in Dobrudja, in contemporary northeastern Bulgaria. The heartland for the Dobrudja revolt was in the "wild forest" region south of the Danube Delta. Bedreddin found disciples among many who were discontent with sultan Mehmed; he became a figurehead for those who felt they had been disenfranchised by the sultan, including disgruntled marcher lords and many of those who had been given timars by Bedreddin as Musa's kadiasker, which had been revoked by Mehmed.

These uprisings posed a serious challenge to the authority of Mehmed I as he attempted to reunite the Ottoman Empire and govern his Balkan provinces. Although they were all eventually stifled, the series of coordinated revolts instigated by Bedreddin and his disciples was suppressed after only great difficulty. Torlak Kemal’s rebellion in Manisa was crushed and he was executed, along with thousands of his followers. Borkluje's rebellion put up more of a fight than the others, defeating first the army of the governor of Saruhan and then that of the Ottoman governor Ali Bey, before finally it was finally crushed by the Vizier Bayezid Pasha. According to the Greek historian Doukas, Bayezid slaughtered unconditionally to ensure the rebellion's defeat, and Borkluje was executed along with two thousand of his followers. Sheikh Bedreddin's own Dobrudja rebellion was a short-lived one, and came to an end when Bedreddin was apprehended by Mehmed's forces and taken to Serres. Accused of disturbing the public order by preaching religious syncretism and the communal ownership of property, he was executed in the marketplace.

Thought and writings

Sheikh Bedreddin was a prolific writer and religious scholar, and a distinguished member of the Islamic religious hierarchy. He is often regarded as a talented voice in religious sciences, particularly for his thoughts on Islamic law. For his works on jurisprudence he is classed among the great scholars of Islamic thought. On the other hand, many condemn him as a heretic for his radical ideas on religious syncretism. Bedreddin advocated overlooking religious difference, arguing against zealous proselytism in favor of a utopian synthesis of faiths. This latitudinarian interpretation of religion was a major part of what allowed him and his disciples to instigate a broad-reaching popular revolt in 1416, unifying a very heterogeneous base of support.

Bedreddin’s religious origins were as a mystic. His form of mysticism was greatly influenced by the work of Ibn al-‘Arabi, and he is known to have written a commentary of al-‘ Arabi's book Fusus al-hikam (The Quintessence of Wisdom). Through his writings, he developed his own form of mysticism. His most significant book, Varidat, or Divine Inspirations, was a compilation of his discourses which reflected on his ideas about mysticism and religion. Bedreddin was a monist, believing that reality is a manifestation of God’s essence, and that the spiritual and physical worlds were inseparable and necessary to one another. As he writes in Varidat, he believed that “This world and the next, in their entirety, are imaginary fantasies; heaven and hell are no more than the spiritual manifestations, sweet and bitter, of good and evil actions.”

Bedreddin’s pantheistic beliefs greatly influenced many of his political and social ideas, particularly the doctrine of “oneness of being.” This doctrine condemns oppositions which its adherents believe hinder the oneness of the individual with God, including oppositions between religions and between the privileged and the powerless. This belief system is reflected in the beliefs of Bedreddin and his disciples, who, among other things, preached that all religions are essentially the same, as well as that ownership of property should be communal. Such ideas appealed greatly to those who felt marginalized in Ottoman society, and this egalitarian ideology played a major role in inspiring popular revolt in 1416.

Sheikh Bedreddin clearly had ambitious political aspirations when he began his rebellion. According to the 15th-century Sunni historian Idris of Bitlis, Bedreddin considered himself the Mahdi, who would bring about God's unity in the world by distributing his lands among his followers. Although Idris' account is partial, Bedreddin's ambitions as a political and religious leader are apparent. He even went so far as to claim that he was descended from the Seljuk royal house, undoubtedly to bolster his legitimacy as a potential ruler. It is plausible that he aspired to win the sultanate.


The revolt of 1416 marked a turning point in the toleration of non-Muslims by the Ottoman state. By crushing the rebellion aggressively and stigmatizing those who revolted, the state condemned popular discontent as illegitimate and further defined its position of opposition to religious nonconformists. After the revolt, Turco-Muslim presence in the Balkans became equivalent to an Ottoman presence. Bedreddin's rebellion made it clear to Ottoman statesmen that religious dissidence could pose a serious threat to their administrative structure, and in the years that followed, Murad II, Mehmed’s successor, took steps to ensure that Islam was further established as the state’s religion. For example, Murad expanded the Janissaries in the wake of the Bedreddin revolt to increase Ottoman military power, but also to create a steady flow of Christians being converted to Islam. This demonstrates a clear shift in Ottoman policy away from toleration of non-Muslims and closer to one of assimilation, a trend that would continue in the coming centuries.

Sects of Bedreddin's followers continued to survive long after his death. His teachings remained influential, and his sectarians were considered a threat until the late sixteenth century. Known as the Simavnis or the Bedreddinlus, a sect of his followers in Dobrudja and Deliorman continued to survive for hundreds of years after his execution. Unsurprisingly, the Ottoman government viewed this group with great suspicion. In the sixteenth century, they were regarded as identical to the Kizilbash, and persecuted along with them. Some of Bedreddin's doctrines also became common among some other mystic sects. One such sect was the Bektashi, a dervish order commonly associated with the Janissaries.

Sheikh Bedreddin continues to be known in Turkey, especially among socialists, communists, and other political leftists. In the twentieth century, he was brought back into the spotlight by the communist Turkish writer Nazim Hikmet, who wrote The Epic of Sheikh Bedreddin to voice opposition to the rise of fascism in the 1930s. Hikmet's work popularized Bedreddin as a historical champion of socialism and an opponent of fascist tyranny, and his name has remained well known to those on the left of the political spectrum. His bones were exhumed in 1924, but his devotees were so fearful of a backlash against Bedreddin's newfound political significance by the Turkish government that he was not buried until 1961. He was finally put to rest near the mausoleum of Mahmud II, in Istanbul.
