Taj as-Salatin (The Crowns of Kings)

The author of Taj al-Salatin (The Crowns of Kings), Bukhari al-Jauhari, underscored in his writings the guidelines for an 'adl (fair/just) kingship and good governance. Hailing from Bukhara (modern day Kazakhstan) he then migrated to the Malay archipelago as a gem merchant, hence the name 'جوهرة' which is Arabic for gems.

Taj al-Salatin, written in Malay Jawi scripture (as seen in the image) was highly influential in the palace courts across the region and heavily referred and influenced other notable scholars/writers/poets including Nur-al Din Raniri (d.1658) and Raja Ali Haji (1808-1873). 

His legacy, after establishing himself as a prominent author and royal court advisor is indeed the Taj al-Salatin, referred and referenced heavily by royal courts in the Malay archipelago including the 12th Sultan of Aceh, Sultan Iskandar Muda (r. 1607-1636) (depicted in the image here opposite Queen Elizabeth I) . 

Bukhari al-Jauhari's roots is the main precursor to the unique linking between Persian/Islamic ethical and political traditions to the Malay sultanates of Aceh, Johor and Terenganu.

Sultan Hossein Shah (born Tengku Long. 1776-1835) the ruler of the Johor-Riau Sultanate is said to have rejected a suggestion by Sir Stamford Raffles (1781-1826) for his engagement in trade. This rejection is said to have stemmed from the advice based on the Taj al-Salatin.
