Trịnh Khả (, 1402 – 1451) close advisor to emperor Lê Thái Tổ, chief ruler of Vietnam during the 1440s, and founder of the powerful Trịnh family. Biography Trịnh Khả, like most of Lê Lợi's chief aids and generals, was from Thanh Hóa Province which is where Lê Lợi was born. During the decade-long Lam Sơn uprising against the Ming dynasty, Trịnh Khả served as an advisor to Lê Lợi. With victory, Trịnh Khả was elevated to a high position in the new court of Emperor Lê Lợi. Trịnh Khả (and the other councilors) were given the privilege of wearing red silk and were called Hành-khiển. Other members of this new elite were: Nguyễn Trãi, Tran Nguyen Han, Lê Sát, Phạm Văn Xảo, Dinh Liêt, and Lê Ngan. When Lê Lợi died in 1433, Lê Sát was appointed regent for the young emperor, Lê Lợi's second son, Lê Thái Tông. Lê Sát made use of his new power to remove rivals from the government, some were killed (like Phạm Văn Xảo), while others, like Trịnh Khả, were sent away to govern distant provinces of Vietnam. Lê Thái Tông officially came of age in 1438 but found Lê Sát was unwilling to give up his power as regent. Lê Thái Tông looked for political allies and found Trịnh Khả. The new emperor appointed Trịnh Khả to command the Palace Guard. A few months later, Lê Sát was accused of ruling in place of the emperor and with the aid of Khả's guards, Lê Sát was arrested and then condemned to death. Not long after this, Lê Ngan was also removed from power, leaving Trịnh Khả as the main power behind Lê Thái Tông. Officially, Trịnh Khả was the head of the Administrative Bureau (Chinh-su-vien) but the next four years were filled with intrigue as the various noble families in the court plotted to expand their power at the expense of their rivals. Trịnh Khả came out on top of this fight, being promoted to the position of Imperial Councilor shortly before Lê Thái Tông became sick and died in 1442. With the death of the young emperor, the new heir to the throne was an infant Lê Nhân Tông. The government was nominally controlled by the boy's mother, Nguyễn Thị Anh (as Dowager Queen and Regent), but she was very young herself. Real power seems to have been wielded by Trịnh
