Gajah Mada
In 1331, she led the army herself to the battlefield with the help of her cousin, Adityawarman, to crush rebellion in the areas of Sadeng and Keta. The decision was partly to resolve the competition between Gajah Mada and Ra Kembar for the army general position to crush Sadeng. In 1334, she appointed Gajah Mada as her new Mahapatih (Javanese title equal to Prime Minister), and Gajah Mada proclaimed his famed Palapa oath, asserting his intention to expand the influence of the kingdom across the archipelago. According to Pararaton, his extraordinary vow surprised the court and state officials who attended his inauguration. Some of them, especially Mada's rival, Ra Kembar, laughed and mocked Mada, ridiculed him as a big-mouthed bluff with an impossible dream. This public humiliation enraged Gajah Mada, resulting in a duel, warranted by Tribhuwana, which led to the death of Ra Kembar and the execution of others that opposed his authority.
