The Reign
Two Brothers and Two Capitals
Yesün Temür died at Shangdu in 1328. In Dadu (Beijing), the Kipchak general El Temür seized power in the name of Khayishan's line and, because Kusala was far away in Central Asia, placed Tugh Temür on the throne. The court at Shangdu enthroned Yesün Temür's young son Ragibagh, and a civil war followed, known as the War of the Two Capitals. El Temür's forces won within a few months.
Tugh Temür then offered the throne to Kusala, who was proclaimed khan in Mongolia early in 1329, with Tugh Temür as his heir. When the brothers met that summer, Kusala died suddenly, very probably poisoned by El Temür's party, and Tugh Temür returned to the throne.
Rewards and Recognition
Tugh Temür's government rewarded its supporters generously. Princely titles were granted on a large scale, imperial grants were restored in 1329, and property confiscated from the defeated Shangdu faction was given to the princes and officials who had backed the restoration of Khayishan's line.
To secure recognition as overlord of the Mongol world, he sent princes with lavish gifts to the Golden Horde, the Ilkhanate and the Chagatai Khanate. He also sent gifts to Eljigidey, the Chagatai khan, who had been a strong supporter of Kusala. The responses were favourable, and relations with the western khanates were closer during his reign than they had been for some time.
El Temür and Bayan
Government in these years was dominated by El Temür and by Bayan of the Merkid clan, the two men most responsible for the restoration. They received honours and power greater than any Yuan official before them, built strong bases in both the army and the bureaucracy, and largely overshadowed the emperor. Tugh Temür honoured his father's former ministers with titles and gave the leaders of the restoration most of the important posts.
Patronage of Art and Learning
Tugh Temür's most lasting contribution was cultural. In 1329 he founded the Kuizhangge, the Pavilion of the Star of Literature, an academy attached to the palace where scholars and connoisseurs, among them the writer Yu Ji and the painter and critic Ke Jiusi, studied and catalogued the imperial collection of calligraphy and painting. He also commissioned the Jingshi Dadian, a great compendium of the institutions and statutes of the Yuan state, completed in 1331.
Unrest
The civil war, campaigns against rebellions among the peoples of the southwest and a series of natural disasters placed heavy strains on the state's resources. A rising in Yunnan proved particularly slow and costly to suppress, although the general Aratnashiri eventually defeated the Lolo (Yi) chiefs and other mountain peoples. Discontent grew at court, and a plot to overthrow the emperor by a descendant of Ananda, the prince who had contested the throne in 1307, was discovered and punished.
