Bunga mas in the context of "Yala Province"

A tributary state is a pre-modern state in a particular type of subordinate relationship to a more powerful state which involved the sending of a regular token of alliance, or tribute, to the superior power (the suzerain). This token often took the form of a substantial transfer of wealth, such as the delivery of gold, produce, or slaves, so that tribute might best be seen as the payment of protection money. It might also be more symbolic: sometimes it amounted to no more than the delivery of a mark of alliance such as the bunga mas (golden flower) that rulers in the Malay Peninsula used to send to the kings of Siam, or the Tribute of the Maltese Falcon that the Grand Master of the Order of St. John used to send annually to the Viceroy of Sicily in order to rule Malta. It might also involve attendance by the subordinate ruler at the court of the hegemon in order to make a public show of submission.

The modern-day heirs of tribute hegemons tend to claim that the tributary relationship should be understood as an acknowledgement of the hegemon's sovereignty in the modern world, whereas former tributary states deny that there was any transfer of sovereignty.
