Mehmet Reşad came into the world on 2 November 1844, in the opulent surroundings of the Çırağa Palace in Istanbul. He was born into the imperial Ottoman family as the son of Sultan Abdülmecid I and Gülcemal Kadınefendi. He was the 35th sultan of the Ottoman dynasty, and the third of Sultan Abdülmecid's four sons who would ascend the throne successively.

Mehmed had three elder sisters: Fatma Sultan, Refia Sultan, and Hatice Sultan, who died in infancy. Tragically, his mother died when he was just seven years old, in 1851, leaving him and his sisters to be raised by his father's senior consort, Servetseza Kadın, who cared for the children as if they were her own.

Education and Intellectual Formation

Reşad's formal education at the palace was regarded by contemporaries as a limited one, though thanks to his comparatively high intelligence he made good use of what he had. He studied Arabic and Persian, and spoke the latter very well. He took piano lessons from an Italian pianist and calligraphy lessons from a famous Ottoman calligrapher, Kazasker Mustafa Izzet Efendi, who designed the giant pendant medallions of the Hagia Sophia. In addition to his linguistic pursuits, Reşad was deeply interested in Mevlevi Sufism and the Masnavi of Rumi. He also became an accomplished poet in the classical Persian style, which was a rare artistic sensibility among his peers in the imperial family.

Years of Confinement Under Abdülhamid II

The defining experience of Reşad Efendi's long pre-reign life was one of enforced seclusion. He became crown prince in 1876 with the ascension of his half-brother Sultan Abdülhamid II, but was essentially kept under house arrest in Dolmabahçe Palace under close surveillance. This confinement lasted over three decades. His brother Abdülhamid was careful to avoid any direct communication with him, and during this period of enforced isolation, Mehmed was deprived of the political experience that could have prepared him for the challenges of ruling.

Sultan Abdülhamid used to say, "I am doing my brother a great favor by not showing him to the public." The wisdom of these words emerged years later. Even the poet Mehmet Akif Ersoy, himself a fierce opponent of Abdülhamid, is recorded as saying that had Abdülhamid paraded his brother before the people as his intended successor, he might never have been dethroned, so starkly did the contrast in capacity between the two brothers speak for itself.

Reşad Efendi married in 1872 at Ortaköy Palace. His first wife was Kamures Kadınefendi, of Azerbaijani origin, with whom he had a son, Prince Mehmed Ziyaeddin Efendi. He subsequently took further wives, including Dürrüaden Kadınefendi, of Circassian origin. Unusually for an Ottoman sultan, he was the only sultan who did not take new wives after becoming sultan.

Accession to the Throne: The "Constitutional Sultan"

When the constitutional order was restored by the Young Turk Revolution of 1908, Reşad Efendi re-emerged from obscurity as the heir apparent. The following year, the 31 March Incident, which was a counter-revolutionary uprising that was suppressed by the CUP's "Action Army", sealed the fate of Abdülhamid II. His reign began at the conclusion of the 31 March Incident on 27 April 1909, which resulted in the deposition of his half-brother Abdülhamid II. Reşad came to the throne largely as a figurehead with no real political power. At the age of 65, Reşad was the oldest person ever to ascend the Ottoman throne.

It was decided to use the regal name "Mehmet" rather than his more personal name "Reşad," upon the suggestion of Ferik Sami Pasha, who wanted to draw a symbolic connection between Mehmet V and the legendary Mehmet the Conqueror, who had captured Constantinople in 1453. Despite this grandiose symbolism, he was called Sultan Reşad by the people.

His enthronement ceremony took place at the Ministry of War in Beyazıt, followed by a sword-girding ceremony at the Eyüp Sultan Mosque. The new sultan received a warm welcome from the people of Istanbul, and in his accession speech declared, "I am the first sultan of liberty, and I am proud of it!",  earning him the sobriquet of the "Constitutional Sultan."

A Ruler Without Power: The CUP's Stranglehold

Despite his symbolic importance, Sultan Mehmet Reşad never exercised meaningful political authority. Due to his meek, weak-willed, and naïve personality and the strength of the Committee of Union and Progress, the government was firmly out of his hands. When the CUP asked something from him he would immediately acquiesce without pushback, typically replying "I am pleased!" or "I am humbled!"

The Sultan was deeply afraid of the men of action within the CUP, and of the possibility that he could end up like one of his predecessors. His uncle Abdülaziz had been deposed and died in suspicious circumstances; his half-brother Murad V had been deposed after suffering a nervous breakdown and spent the rest of his life under house arrest; and Abdülhamid himself had now been deposed and was held under guard in Salonica.

The members of the CUP formed the entourage of the new sultan from people they trusted alone. This suffocating political environment was captured by the anecdote of his niece Münire Sultan, who begged her uncle not to sign the death warrant of her husband Salih Pasha, who had been implicated, largely as a pretext, in an assassination following the 1913 CUP coup. The sultan responded, "My dear niece, they'll hang you, then me too," and signed the death warrant along with others.

The Goodwill Tour of Rumelia

One of the few genuine public roles Mehmet Reşad was permitted to play came in the summer of 1911. In June 1911, he embarked on an imperial tour of Salonica and Monastir, stopping by Florina on the way. He also visited Skopje and Pristina, where he attended Friday prayers at the Tomb of Sultan Murad. The visit was recorded on film and in photographs by the Manaki brothers. During the tour he conducted Friday prayers, issued amnesties for political prisoners, and distributed aid to foster loyalty among diverse ethnic communities. It would soon prove to be the last visit of an Ottoman sultan to the Rumelian provinces before the catastrophe of the Balkan Wars the following year.

The Italo-Turkish War and the Balkan Catastrophes

The years 1911–1913 brought a cascade of military disasters that devastated Ottoman territory, each one beyond the sultan's power to prevent or shape. In 1911, Italy attacked Libya. The CUP government had withdrawn the troops that Sultan Abdülhamid had once deployed there, and for this reason the Libyan coastline was easily occupied, although resistance organized by Ottoman officers and the Senussi order denied Italy control of the interior well into the 1930s. Under the Treaty of Ouchy, the Ottoman Empire formally ceded Tripolitania and the Dodecanese Islands, including Rhodes, to Italy.

Then came the Balkan Wars. Romania, Serbia, Montenegro, Bulgaria, and Greece allied together and attacked the Ottoman Empire in 1912. In what became known as the First Balkan War, the Turkish army was heavily defeated due to partisanship and mismanagement. Rumelia was lost. Hundreds of thousands of Muslims became refugees. The trauma was immense as territories held for centuries vanished within months. The Ottomans made some small gains in the Second Balkan War, recapturing the peninsula comprising East Thrace up to Edirne, but this was only partial consolation. The bulk of Ottoman territories had been lost forever.

The 1913 Coup and the Consolidation of CUP Rule

The Balkan disaster provided the pretext for an even more brazen seizure of power. On 23 January 1913, Enver Bey and a group of CUP officers raided the Sublime Porte in what became known as the "Babıali Coup", shooting the Minister of War dead and forcing the resignation of Grand Vizier Kamil Pasha. Sultan Mehmet Reşad, under overwhelming pressure, was compelled to appoint the CUP protégé Mahmut Şevket Pasha as Grand Vizier. The CUP, which had been in de facto power since 1908, took complete control by using the disaster in the Balkans as a pretext. In June 1913, when Grand Vizier Mahmut Şevket Pasha was assassinated, the CUP used this as an excuse to crush all remaining opponents. In Istanbul, gallows were erected for days. What remained of genuine political pluralism in the empire was effectively extinguished. The triumvirate of Enver Pasha, Talat Pasha, and Cemal Pasha, the so-called "Three Pashas" now held supreme authority.

First World War: The Declaration of Jihad and Its Aftermath

The path to the First World War was forged entirely without the sultan's meaningful participation. When War Minister Enver Pasha ordered the bombardment of Russian Black Sea positions and dragged the country into war in late October 1914, neither the Grand Vizier nor the sultan had been informed in advance.

Nevertheless, Mehmet Reşad's most consequential formal act as caliph followed shortly after. Despite his personal preference that the country stay out of further conflict, and his known disfavour of Enver Pasha's pro-German policy, Sultan Reşad's most significant political act was to formally declare a jihad against the Entente Powers on 14 November 1914. The proclamation called for Muslims to support the Ottomans in Entente-controlled areas and for jihad against "all enemies of the Ottoman Empire, except the Central Powers." It included five fatwas endorsed by 29 religious authorities. Critics at the time, most notably the Dutch orientalist Christiaan Snouck Hurgronje, dismissed it as a "jihad made in Germany," reflecting the German strategic ambition to foment Muslim uprisings in British and French colonial territories.

This was the last genuine proclamation of jihad in history by a Caliph, as the Caliphate was abolished in 1924. The proclamation had no noticeable effect on the war; the Arabs eventually joined the British forces against the Ottomans in the Arab Revolt of 1916. As a direct consequence of the Ottoman entry into the war, the British annexed Cyprus, while the Khedivate of Egypt proclaimed its independence and became a British protectorate. These were provinces that had at least been under nominal Ottoman rule.

Mehmet Reşad hosted Kaiser Wilhelm II in Constantinople on 15 October 1917, and was made a Generalfeldmarschall of the German Empire on February 1, 1916, honors that were more ceremonial than substantive, reflecting the sultan's status as a symbolic rather than genuine partner in the wartime alliance.

In 1915, Ottoman forces successfully fended off an Allied invasion at Gallipoli and captured a large British garrison at Kut. During that same year, the CUP initiated the Armenian deportations against the Sultan's wishes, though his private disapproval of his government's actions was entirely inconsequential.

Final Years and Death

As the war ground on disastrously, the sultan's marginalisation became total. When Grand Vizier Sait Halim Pasha resigned in February 1917 and was replaced by Talat Pasha, the most powerful of the Three Pashas, Mehmet Reşad lost even the semblance of involvement in state affairs. There were instances where he was not even informed of major political decisions. His health began to deteriorate in parallel with the fortunes of the empire he nominally led.

Sultan Mehmet Reşad died at Yıldız Palace in Istanbul on 3 July 1918. He was 73 years old and passed away just four months before the end of the First World War, and thus did not live to see the final collapse of the Ottoman Empire. He was buried in the historic Eyüp district of Istanbul, close to the mosque where he had been girded with the Sword of Osman at the outset of his reign, a fitting symmetry for a sultan whose life had been framed by ceremony rather than power.

Legacy and Historical Assessment

Mehmet Reşad's nine-year reign was, by any measure, a reign of catastrophe: it featured three coups d'état, four wars, eleven governments, and numerous uprisings. The empire he inherited in 1909 was weakened but still vast; the empire he left behind in 1918 was on the verge of extinction.

Yet the sultan himself was largely a victim of his circumstances rather than their architect. Decades of isolation under Abdülhamid had left him without the tools such as the experience, the networks, the will to dominate, all of which were needed to resist the CUP's seizure of power. A kind and gentle man, educated in traditional Islamic subjects and Persian literature, he showed a keen interest in Ottoman and Islamic history; nevertheless, he lacked the ability to govern. His personal reservations  about the war, about the Armenian deportations, about the cult of German military partnership were, at every turn, rendered irrelevant by the men who held real power.

History remembers him above all as the last caliph to issue a genuine declaration of jihad, and as a man whose reign marked the final unraveling of the Ottoman imperial order,  a reign he witnessed, but could not shape.
