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 submission, 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. Or it might be more symbolic: sometimes it amounted to no more than the delivery of a mark of submission 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. A formalized tribute system developed in East Asia with many neighboring East, Central, and Southeast Asian countries and regions becoming tributary states of various Chinese dynasties. Historically, the Emperor of China saw himself as the emperor of the entire civilized world. It was not possible for such an emperor to have equal diplomatic relations with any other power, and so all diplomatic relations in the region were construed by the Chinese as tributary. The disdain of the state ideology of Confucianism for trade, and the belief that Chinese civilization had no need of products or technology from outside meant that trade, when it was permitted, was also construed as tributary. Diplomatic missions and trading parties from non-Chinese regions were interpreted in Chinese records as being tributary, regardless of the intention of those regions.
