Trịnh Kiểm
In 1556, Emperor Lê Trung Tông died without an heir, and Trịnh Kiểm aimed to seize the Lê dynasty's throne but he was still worried about public opinion. Therefore, he sought advice from the former mandarin Nguyễn Bỉnh Khiêm who was living a secluded life. Nguyễn Bỉnh Khiêm advised that Trịnh Kiểm should not take the Lê dynasty's throne although the Lê dynasty was just a puppet. Trịnh Kiểm decided to enthrone on the Lê dynasty's throne Lê Duy Bang, who was 6th generation descendent of Lê Trừ (older brother of emperor Lê Thái Tổ). Lê Duy Bang took the throne with the title Lê Anh Tông and the Trịnh lords continually controlled the government with the emperor as the figurehead.
