Trần dynasty
The Trần dynasty, also known as the House of Trần, was a Vietnamese medieval royal clan that ruled over the Kingdom of Đại Việt from 1225 to 1400. The dynasty was founded when emperor Trần Thái Tông ascended to the throne after his uncle Trần Thủ Độ orchestrated the overthrow of the Lý dynasty. The final emperor of the dynasty was Thiếu Đế, who at the age of five years was forced to abdicate the throne in favor of his maternal grandfather, Hồ Quý Ly. The Trần dynasty defeated three Mongol invasions, most notably in the decisive Battle of Bạch Đằng River in 1288.
