Mehmed V Reshad (Ottoman Turkish: محمد خامس Meḥmed-i ẖâmis, Turkish: Mehmed V Reşad or Reşat Mehmet) (2/3 November 1844 – 3/4 July 1918) was the 35th Ottoman Sultan. He was the son of Sultan Abdülmecid I.^{[citation needed]} He was succeeded by his half-brother Mehmed VI.

He was born at Topkapı Palace, Constantinople. Like many other potential heirs to the throne, he was confined for 30 years in the Harems of the palace. For nine of those years he was in solitary confinement. During this time he studied poetry of the old Persian style and was an acclaimed poet. On his ninth birthday he was ceremoniously circumcised in the special Circumcision Room (Sünnet Odasi) of Topkapı Palace.

His reign began on 27 April 1909 but he was largely a figurehead with no real political power, as the Ottoman state affairs were largely run by the Three Pashas since the Young Turk Revolution in 1908. Mehmed V's only significant political act was to formally declare Jihad against the Entente Powers (Allies of World War I) on 11 November 1914, following the Ottoman government's decision to join the First World War on the side of the Central Powers.

World War I (WWI), which was predominantly called the World War or the Great War from its occurrence until 1939 (World War II), and the First World War or World War I thereafter, was a major war centred in Europe that began on 28 July 1914 and lasted until 11 November 1918. It involved all the world's great powers, which were assembled in two opposing alliances: the Allies (based on the Triple Entente of the United Kingdom, France and Russia) and the Central Powers (originally centred around the Triple Alliance of Germany, Austria-Hungary and Italy; but, as Austria–Hungary had taken the offensive against the agreement, Italy did not enter into the war). These alliances both reorganised (Italy fought for the Allies), and expanded as more nations entered the war. Ultimately more than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. More than 9 million combatants were killed, largely because of enormous increases in lethality of weapons, thanks to new technology, without corresponding improvements in protection or mobility. It was the sixth-deadliest conflict in world history, subsequently paving the way for various political changes such as revolutions in the nations involved.

Mehmet VI (Ottoman Turkish: محمد سادس Meḥmed-i sâdis, وحيد الدين Vahidettin. Turkish: Mehmed Vahideddin or Mehmet Vahdettin) (14 January 1861 – 16 May 1926) was the 36th and last Sultan of the Ottoman Empire, reigning from 1918 to 1922. The brother of Mehmed V, he succeeded to the throne as the eldest male member of the House of Osman after the 1916 suicide of Abdülaziz's son Yusuf Izzettin Efendi, the heir to the throne. He was girded with the Sword of Osman on 4 June 1918, as the thirty-sixth padishah. His father was Sultan Abdülmecid I and mother was Gülüstü (1831 – May 1861), a Circassian. Mehmed was removed from the throne when the Ottoman sultanate was abolished in 1922.

Mehmet VI ruled as His Imperial Majesty, The Grand Sultan Mehmed VI Vahid ed-din, Emperor of the Ottomans, Commander of the Faithful and Successor of the Prophet of the Universe.^{[citation needed]}

He was born in the Dolmabahçe Palace or the Beşiktaş Palace, Beşiktaş, both in Constantinople. On his ninth birthday he was ceremonially circumcised in the special Circumcision Room (Sünnet Odasi) of Topkapı Palace.

Mehmed I Çelebi (Ottoman: چلبی محمد, Mehmed I or Mehmed Çelebi) (1390, Bursa – May 26, 1421, Edirne, Ottoman Empire) was a Sultan of the Ottoman Empire (Rûm) from 1413 to 1421. He was one of the sons of Bayezid I and Devlet Hatun.

After the Ottoman Interregnum, when Mehmed stood as victor in 1413, he crowned himself sultan in Edirne. He restored the empire, moved the capital from Bursa to Edirne, and conquered parts of Albania, the Jandarid emirate, and the Armenian Kingdom of Cilicia from the Mamelukes. Taking many of his achievements into consideration, Mehmed is widely known as the "second founder" of the Ottoman Empire.

Reign of Mehmed I, as Sultan of the re-united empire, had lasted only eight years. But he had been an independent prince for nearly the whole preceding period of eleven years that passed between his father's captivity at Ankara and his own final victory over his brother Musa Çelebi at Chamurli.

He was buried in Bursa, in a mausoleum erected by himself near the celebrated mosque which he built there, and which, from its decorations of green porcelain, is called the Green Mosque. Mehmed I also completed the mosque at Bursa, which his grandfather Murad I had commenced, but which had been neglected during in reign of Bayezid. Mehmed founded in the vicinity of his own 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.

Recep Tayyip Erdoğan (IPA: [ɾeˈd͡ʒep tajˈjip ˈæɾdoan]; born 26 February 1954) has been Prime Minister of Turkey since 2003 and is chairman of the ruling Justice and Development Party (AK Party), which holds a majority of the seats in the Grand National Assembly of Turkey. Erdoğan served as Mayor of Istanbul from 1994 to 1998. He graduated in 1981 from Marmara University's Faculty of Economics and Commercial Sciences. Erdoğan was also a semi-professional footballer from 1969 to 1982.

Erdoğan was elected Mayor of Istanbul in the local elections of 27 March 1994. He was banned from office and sentenced to a prison term for reciting a poem during a public address in the province of Siirt on 12 December 1997. The poem was allegedly quoted from a book published by a state enterprise and one that had been recommended to teachers by the Ministry of Education. After six months in prison, Erdoğan established the Justice and Development Party (AK Party) on August 14, 2001. From its first year, the AK Party became the largest publicly-supported political movement in Turkey. In the general election of 2002 the AK Party won nearly two-thirds of the seats in parliament, forming the first single-party government for 9 years.
