"Sultan of Sultans" is the literal
English translation of the original
Turkish '''Sultan es-Selatin''' or '''Sultan us-Selatin'''. It is similar to the title
Great Sultan, which is translated from
Arabic.
As with various other laudatory titles of Semitic origin, such as "
King of Kings", 'Sultan of Sultans' can express a claim of
imperial rank up to and including universal legitimate
sovereignty. Although the notion and title of an
emperor is largely alien to Islamic tradition, the
Ottoman dynasty which, employed the title of "Sultan of Sultans" in its official full style had perhaps the best claim to usage, due to its territorial extent and great length. The Ottomans also adopted the traditional imperial term "Kaisar" for their own ruler (the
Padishah).
The
Shahanshah (
Persian for "King of Kings") of
Iran also claimed, with slightly less legitimacy to be the "Sultan of Sultans". These claims, made against the
Ottomans were tied to the conflict between the
Sunni and
Shiite branches of
Islam.
The title has also been appropriated for local use by various minor Muslim rulers, especially in
Bengal.
