The Ottoman Empire, also known as the Ottoman Caliphate, was ruled by a series of sultans throughout its existence. The number of rulers, or sultans, varied over the centuries due to factors such as succession disputes, coups, and assassinations.
The empire’s history spans over six centuries, from its establishment around 1299 to its dissolution in 1922. During this time, numerous rulers ascended to the throne, each leaving their mark on the empire’s governance, culture, and military conquests.

The Ottoman Empire’s early period saw the reigns of notable sultans such as Osman I, Orhan, Murad I, and Bayezid I, who expanded the empire’s territory through military campaigns in Anatolia and the Balkans.
The period of expansion and consolidation reached its peak under the rule of Mehmed II, commonly known as Mehmed the Conqueror, who captured Constantinople in 1453, marking the end of the Byzantine Empire and establishing Istanbul as the new Ottoman capital.
Following Mehmed II, a succession of sultans ruled the empire, including Selim I, known for his conquests in the Middle East and North Africa, and Suleiman the Magnificent, who presided over the empire’s golden age, overseeing vast territorial expansion and significant cultural achievements.
However, the empire faced challenges in the subsequent centuries, including military defeats, internal strife, and economic decline. This period also witnessed the reigns of less prominent sultans, as well as instances of palace intrigue and power struggles among different factions within the Ottoman elite.
The 19th century brought further turmoil to the empire, with the rise of nationalist movements and external pressures from European powers. During this period, the Ottoman throne saw a succession of sultans attempting to modernize and reform the empire, including Mahmud II, Abdulmejid I, Abdulaziz, and Abdulhamid II.
The Tanzimat reforms initiated in the mid-19th century aimed to modernize the Ottoman state and society, but they faced resistance from conservative elements and ultimately proved insufficient to prevent the empire’s decline.
By the early 20th century, the Ottoman Empire was known as the “sick man of Europe,” facing internal unrest, ethnic tensions, and territorial losses. The reign of Sultan Mehmed V and his successor Mehmed VI witnessed the empire’s involvement in World War I and its eventual defeat.
The dissolution of the Ottoman Empire after World War I led to the end of the sultanate, with the last Sultan, Mehmed VI, being deposed in 1922. The Republic of Turkey was established in 1923, marking the end of centuries of Ottoman rule.
In summary, while it is difficult to provide an exact number of Ottoman rulers due to the empire’s complex history and the varying lengths of individual reigns, the Ottoman Empire was governed by a succession of sultans over six centuries, each contributing to its rise, expansion, and eventual decline.

Certainly, let’s delve deeper into the rich history of the Ottoman Empire and the succession of rulers who shaped its destiny over the centuries.
The Ottoman Empire emerged in the late 13th century in the region of Anatolia, under the leadership of Osman I, from whom the empire derived its name. Osman and his descendants, known as the Osmanli or Ottoman Turks, gradually expanded their territory through a combination of military conquests and alliances, eventually establishing a vast multi-ethnic and multi-religious empire encompassing Anatolia, the Balkans, the Middle East, and North Africa.
Following Osman I, his son Orhan succeeded him as the ruler of the burgeoning Ottoman state. Orhan continued his father’s expansionist policies, consolidating Ottoman control over Anatolia and extending into the Balkans. During his reign, the Ottoman capital was moved from Söğüt to Bursa, laying the foundation for the empire’s future growth and prosperity.
Orhan was succeeded by his son Murad I, who ascended to the throne in 1362. Murad I continued the Ottoman expansion into Europe, capturing Adrianople (modern-day Edirne) in 1365, which became the empire’s new capital. He also introduced significant military reforms, including the establishment of the Janissary corps, an elite infantry force recruited through the devshirme system.
Following Murad I’s death in 1389, his son Bayezid I, also known as Bayezid the Thunderbolt, became the next Ottoman sultan. Bayezid’s reign was marked by ambitious military campaigns, including the Ottoman siege of Constantinople in 1396 and his victory over a European coalition at the Battle of Nicopolis. However, Bayezid’s expansionist ambitions were halted by his defeat and capture by the Timurid ruler Timur at the Battle of Ankara in 1402, leading to a period of crisis known as the Ottoman Interregnum.
The Ottoman Interregnum was characterized by a power struggle between Bayezid’s sons for control of the empire. Eventually, Mehmed I emerged victorious and restored stability, founding the Ottoman House of Osman and initiating a period of consolidation and recovery.
Mehmed I was succeeded by his son Murad II, who ruled the empire during a period of renewed expansion and conflict. Murad II faced numerous challenges, including the Byzantine resurgence under John VI Kantakouzenos and the rise of the Serbian despotate under Đurađ Branković. Despite these challenges, Murad II managed to maintain Ottoman dominance in the Balkans and Anatolia, securing his legacy as a capable ruler.
The next significant figure in Ottoman history was Mehmed II, also known as Mehmed the Conqueror, who ascended to the throne in 1444 and reigned until 1446, and then again from 1451 to 1481. Mehmed II is perhaps best known for his conquest of Constantinople in 1453, which marked the end of the Byzantine Empire and solidified Ottoman control over the strategic crossroads between Europe and Asia.
Mehmed II’s reign also witnessed the consolidation of Ottoman power in the Balkans, as well as military campaigns in Anatolia, the Levant, and North Africa. He implemented administrative reforms, centralized the government, and promoted cultural and intellectual achievements, earning him the title of “the Conqueror” and leaving a lasting impact on Ottoman history.
Following Mehmed II, a succession of sultans ruled the empire, each facing their own set of challenges and opportunities. Selim I, also known as Selim the Grim, ascended to the throne in 1512 and expanded the empire’s territory into the Middle East and North Africa, defeating the Safavid Empire at the Battle of Chaldiran in 1514 and conquering the Mamluk Sultanate in 1517, thus bringing the holy cities of Mecca and Medina under Ottoman control.
Suleiman the Magnificent, who reigned from 1520 to 1566, is often regarded as the greatest Ottoman sultan. Suleiman presided over a period of unprecedented territorial expansion, military conquests, and cultural flourishing, earning him the epithet “the Magnificent” in the West and “the Lawgiver” (Kanuni) in the Ottoman Empire.
Suleiman’s reign saw Ottoman dominance in the Mediterranean, the Balkans, and the Middle East, as well as significant architectural and artistic achievements, exemplified by landmarks such as the Süleymaniye Mosque and the Suleymaniye Complex in Istanbul.
In the centuries that followed, the Ottoman Empire continued to expand and evolve under the leadership of successive sultans, including Selim II, Murad III, Mehmed III, Ahmed I, and Osman II, among others. These rulers presided over periods of both prosperity and decline, as the empire faced internal rebellions, external threats, and economic challenges.
The 19th century brought significant changes to the Ottoman Empire, as it grappled with the impact of European imperialism, nationalist movements, and internal reforms. Mahmud II, who ascended to the throne in 1808, initiated a series of reforms known as the Tanzimat, aimed at modernizing the empire’s administrative, legal, and educational systems.
Abdulmejid I, who ruled from 1839 to 1861, continued Mahmud II’s reform efforts, implementing measures such as the Hatt-ı Şerif of Gülhane (Hatt-ı Hümayun), which granted equal rights to all Ottoman subjects regardless of religion or ethnicity.
Abdulaziz, who reigned from 1861 to 1876, pursued a policy of modernization and westernization, overseeing the construction of railways, telegraph lines, and modern infrastructure projects. However, his reign was marred by financial difficulties, corruption, and increasing pressure from European powers.
Abdulhamid II, who became sultan in 1876, attempted to strengthen the empire’s central authority and preserve its territorial integrity in the face of growing internal unrest and external threats. His rule was characterized by authoritarianism, censorship, and suppression of dissent, leading to discontent among various ethnic and nationalist groups within the empire.
The reign of Abdulhamid II came to an end with the Young Turk Revolution of 1908, which forced him to restore the Ottoman constitution and share power with a parliament. However, internal divisions and external pressures continued to weaken the empire, culminating in its involvement in World War I.
The Ottoman Empire’s participation in World War I on the side of the Central Powers proved disastrous, leading to defeat, territorial losses, and the disintegration of the empire. The last Ottoman Sultan, Mehmed VI, was deposed in 1922 following the Turkish War of Independence led by Mustafa Kemal Atatürk.
In 1923, the Republic of Turkey was established, marking the end of the Ottoman Empire and the transition to a modern secular state. The legacy of the Ottoman sultans and their contributions to history, culture, and civilization continue to be studied and debated to this day, reflecting the enduring impact of one of the world’s most significant empires.
