Sultan (Arabic: سلطان) is an Islamic title, with several historical meanings. Originally it was an Arabic language abstract noun meaning "strength", "authority", or "rulership", derived from the Arabic masdar سلطة sulṭah, meaning "authority" or "power". Later, it came to be used as the title of certain Muslim rulers who claimed almost full sovereignty in practical terms (i.e., the lack of dependence on any higher ruler), without claiming the overall Caliphate, or it was used to refer to a powerful governor of a province within the caliphate. It then developed some further meanings in certain contexts.
Sultan Bayezid: Ottoman Empire - Oil on Canvas by Haydar Hatemi-1999
The dynasty and lands ruled by a Sultan are called a Sultanate (Arabic: سلطنة).
The title carries moral weight and religious authority, as the ruler's role was defined in the Qur'an. The Sultan however is not a religious teacher himself. Of course in constitutional monarchies, the sultanship can be reduced to a more limited role.
The first to carry the title of 'Sultan' was the Turkmen chief Mahmud of Ghazni (ruled 998 - 1030). Later, 'Sultan' became the usual title of rulers of Seljuk and Ottoman Turks and Ayyubid and Mamluk rulers in Egypt. In the later stages Sultan was used mostly for the wives of the emperor. The religious validation of the title was illustrated by the fact that the shadow Caliph in Cairo bestowed the title "Sultan" on Murad I, the third ruler of the emerging Ottoman Empire in 1383; its earlier sovereigns had been (protocollary 'mere') Beys or Emirs.
At later stages, lesser rulers assumed the style "sultan", as was the case for the earlier leaders of today's royal family of Morocco. Today, only the Sultan of Oman, the Sultan of Brunei (both sovereign nations), the Sultans of Johor, Kedah, Kelantan, Pahang, Perak, Selangor and Terengganu (within the constitutive states of the federation) in Malaysia, and some titular sultans found in the southern Philippines and Java (Indonesia) regions still use the title. The sultan's domain is properly called a sultanate. A feminine form, used by Westerners, is sultana or sultanah; the very styling misconstrues the roles of wives of sultans. In a similar usage, the wife of a German Field-Marshal might be styled Feldmarschallin (in French, similar constructions of the type madame la maréchalle are quite common).
Among those modern hereditary rulers who wish to emphasize their secular authority under the rule of law, the term is gradually being replaced by 'king' (e.g. Malik in Arabic).
Compound ruler titles
These are generally secondary titles, either lofty 'poetry' or with a message; e.g.:
Mani Sultan = Manney Sultan, meaning 'the Pearl or rulers', or less poetically Honoured Monarch, was a subsidiary title, part of the full style of the Maharaja of Travancore
Certain secondary titles have a devout Islamic connotation, e.g. Sultan ul-Mujahidin as champion of jihad bis saif (holy war to establish Islamic rule)
Sultanic Highness was a rare, hybrid western-Islamic honorific style, exclusively used by the son, daughter-in-law and daughters of Sultan Husain Kamil of Egypt (a British protectorate since 1914), who bore it with their primary titles of Prince (Arabic Amir, Turkish Prens) or Princess, after 11 October 1917. They enjoyed these for life, even after the Royal Rescript regulating the styles and titles of the Royal House after the Egyptian Independence in 1922, when the sons and daughters of the newly styled King (Arabic Misr al-Malik, considered a promotion) were granted the style Sahib(at) us-Sumuw al-Malik, or Royal Highness).
This was the authentic style, commonly rendered as sultan, of the Islamic monarchs of the ruling house of Oman, in both its realms:
Oman — Sultan of Oman, on the southern coast of the Arabian peninsula, still an independent sultanate, since 1784, two years before the imamate lost temporal power in 1786 (assumed the formal style of Sultan in 1861)
Sultanate of Zanzibar two incumbents (from the Omani dynasty) since the de facto separation from Oman in 1806, the last assumed the style Sultan in 1861 at the formal separation under British auspices; since 1964 union with Tanganyika part of Tanzania)
in Morocco, till Mohammed V changed the style to Malik (king) on 14 August 1957, maintaining the subsidiary style Amir al-Mu´minin (Commander of the Faithful)
the Maore (or Mawuti) sultanate on Mayotte(separated from the Comoros)
Maliki
This was the alternative native style (apparently derived from Malik, the Arabic word for King) of the Sultans of the Kilwa Sultanate, in Tanganyika (presently the continental part of Tanzania)
Swahili sultan
Mfalume is the (Ki)Swahili title of various native Muslim rulers, generally rendered in Arabic and in western languages as Sultan:
the Sarkin Damagaram since the 1731 founding of the Damagaram state (later capital Zinder)
in Nigeria most monarchies has a native title; when most in the north converted to Islam, Muslim titles were generally adopted, such as Emir- Sultan has been used in
Furthermore, the Qa´id Jami al-Muslimin (Leader of the Community of Muslims) of Pingnan Guo ("Pacified South State", a major Islamic rebellious polity in western Yunnan province) is usually referred to in foreign sources as Sultan
In the Riau archipelago: sultanate of Lingga-Riau by secession in 1818 under the expelled sultan of Johore (on Malaya) Sultan Abdul Rahman Muadzam Syah ibni al-Marhum Sultan Mahmud
Furthermore, the ruler of Luak Jelebu, one of the constitutive states of the Negeri Sembilan confederation, had the style Sultan in addition to his principal title Undang Luak Jelebu.
In the Ottoman dynastic system, male descendants of the ruling Padishah (in the West also known as Great Sultan), enjoyed a style including Sultan, so this normally Monarchic title is used equivalent to a western prince of the blood: Daulatlu Najabatlu Shahzada Sultan (given name) Hazretleri Effendi; for the Heir Apparent however, the style was Daulatlu Najabatlu Vali Ahad-i-Sultanat' (given name) Effendi Hazlatlari, i.e. Crown Prince of the sultanate.
The sons of Imperial Princesses, excluded from the Ottoman imperial succession, were only styled Sultanzada (given name) Bey-Effendi, i.e. Son of a Prince[ss] of the dynasty.
In certain Muslim states, Sultan was also an aristocratic title, as in the Tartar Astrakhan Khanate
The Sultan Valide was the title reserved for the mother of the ruling sultan.
Military rank
In a number of post-caliphal states under Mongol or Turkic rule, there was a feudal type of military hierarchy, often decimal (mainly in larger empires), using originally princely titles (Khan, Malik, Amir) as mere rank denominations.
In the Persian empire, the rank of Sultan was roughly equivalent to a western Captain, socially in the fifth rank class, styled 'Ali Jah
Use in Western popular culture
The term Sultan is also used in modern pop vernacular to describe someone who has reached the peak of their profession, the elite of their class.
