Question

world history 7b

Answer 1

During his 20 years of rule, Yung-lo brought the Ming dynasty to the zenith of its power. He initiated several institutional innovations designed to strengthen his authority. The major change was the transfer of the imperial seat to Peking, which formally became the capital in 1421. The government agencies in Nanking were not abolished but were made subordinate to those in Peking. He also inaugurated the rule of allowing Hanlin scholars to participate in the deliberation of state affairs, but he had them counterchecked by the eunuchs, who began to rise in political importance.

Several construction works were undertaken during Yung-lo's rule, the most important ones being the dredging of the Grand Canal (1411) and the rebuilding of Peking (1417-1420).
