Sultan is a position with several historical meanings. Originally, it was an Arabic abstract noun meaning "strength", "authority", "rulership", derived from the verbal noun سلطة sulṭah, meaning "authority" or "power". Later, it came to be used as the title of certain rulers who claimed almost full sovereignty without claiming the overall caliphate, or to refer to a powerful governor of a province within the caliphate. The adjectival form of the word is "sultanic", and the state and territories ruled by a sultan, as well as his office, are referred to as a sultanate.
A ruler, sometimes called a rule, scale or a line gauge, is an instrument used to make length measurements, whereby a user estimates a length by reading from a series of markings called "rules" along an edge of the device. Commonly the instrument is rigid and the edge itself is a straightedge, which additionally allows one to draw straight lines. Some rulers, such as cloth or paper tape measures, are non-rigid. Specialty rulers exist that have flexible edges that retain a chosen shape; these find use in sewing, arts, and crafts.

It first appears among the Rouran and then the Göktürks as a variant of khagan and implied a subordinate ruler. In the Seljuk Empire, it was the highest noble title, ranking above malik (king) and emir (prince). In the Mongol Empire it signified the ruler of a horde (ulus), while the ruler of all the Mongols was the khagan or great khan. The title subsequently declined in importance. During the Safavid and qajar dynasty it was the title of an army general high noble rank who ruling a province, and in Mughal India it was a high noble rank restricted to courtiers.

Fajia, translated as Legalism, is one of Sima Qian's six classical schools of thought in Chinese philosophy. Compared in the West with political realism and even the model-building of Max Weber, the "fa school of thought" represents several branches of what Feng Youlan called "men of methods", who contributed greatly to the construction of the bureaucratic Chinese empire. Although lacking a recognized founder, the earliest persona of the Fajia is often considered Guan Zhong, while Chinese historians commonly regard Li Kui as the first Legalist philosopher.
