The Mongol collapse and rise of the Ming dynasty under Zhu Yuanzhang, the peasant emperor led to a major expansion in the economic power of the Kong Dukes in Qufu as their estate grow and they acquired more economic resources and land despite the fact that the Ming clipped the political power of the Dukedom from what it had been under the Song, Jin and Yuan. The Ming banned the Dukes from simultaneously holding bureaucratic positions along with their Ducal title whereas the Song, Jina and Yuan had given administration positions as officials in the central court or region or military positions to the reigning Kong dukes. The Ming made sure culture and ritual were the only duties of the Duke. The power sharing arrangement between the magistrate and Duke in Qufu which began in the late Yuan was also fixed in the Ming and institutionalized. The economic power of the Kong Dukes under the Ming led them to be better able to do behind the scene manipulation in the Ming bureaucracy in the capital locally to gain political influence.
