With the death of Zhengde and ascension of Jiajing, the politics at court shifted in favor of the Neo-Confucian establishment which not only rejected the Portuguese embassy of Fernão Pires de Andrade (d. 1523), but had a predisposed animosity towards Tibetan Buddhism and lamas. Evelyn S. Rawski, a professor in the Department of History of the University of Pittsburgh, writes that the Ming's unique relationship with Tibetan prelates essentially ended with Jiajing's reign while Ming influence in the Amdo region was supplanted by the Mongols.
