 Letters exchanged between these rulers, several of which has been recovered especially in Amarna and Hittite archives, provide details of this diplomacy.The case of "maharaja" ("great "raja"", great king and prince, in Sanskrit and Hindi) on the Indian subcontinent, originally reserved for the regional hegemon such as the Gupta, is an example how such a lofty style of this or an alternative model can get caught in a cycle of devalution by "title inflation" as ever more, mostly less powerful, rulers adopt the style.This is often followed by the emergence of one or more new, more exclusive and prestigious styles, as in this case "maharajadhiraja" (great king of kings").
