Temür made regarding success, and saw favourable responses. Thus Tugh Temür was able to re-establish suzerainty over the Mongol world for himself and to maintain a close relationship with the three western khanates. Administration and court life The four-year reign of Jayaatu Khan Tugh Temür was dominated by El Temur and Bayan of the Merkid. As the persons who had been chiefly responsible for making the restoration possible, they acquired a measure of power and honour that had never before been attained by any official in the Yuan. They built their own power bases in the bureaucracy and the military, and their role overshadowed Tugh Temür. Tugh Temür honoured his father's former ministers and gave them honorific titles, and restored the honours of Sanpo and Toghto who had been persecuted by Ayurbarwada. The participants in the restoration were given most of the positions of importance in his administration. A few of the Muslims held posts in provinces, however, they did not have any position in the central government. In the latter part of 1330 the Emperor went in person to perform the great sacrifice to the sky, which was done by deputy. This was followed by a general amnesty, and by the proclamation of his young son Aratnadara as heir apparent in January 1331. Tugh Temür's consort Budashiri, having a grudge against Babusha, the widow of Kusala, had her assassinated by a eunuch. Then she sent Kusala's son Toghon Temür in exile to Korea to secure her son's succession; but Aratnadara died one month after his designation as heir. This sudden death of his son completely upset Tugh Temür's plan for succession. Jayaatu Khan Tugh Temür caused his another son, Gunadara (Kulatana), to live with El Temur and recognize him as his father, and changed his name to El Tegus. Because a budget deficit of the government drastically increased, and reached 2.3 million ding of paper currency in 1330 alone, Tugh Temür's court attempted to curtail its spending on such items as imperial grants, Buddhist sacrifices, and palace expenses. With those measures, they could keep the budget deficit within manageable figure, and had sufficient grain reserves at its disposal. Prince Tugel Rebellion The added costs of the war against the loyalists and the suppression of the revolts by the ethnic minorities, and natural disasters heavily taxed resources of Tugh Temür's government. The war in Yunnan continued with doubtful success, but
