Lý dynasty
Vietnamese Buddhism reached its zenith during the Lý dynasty (1009–1225), beginning with the founder Lý Thái Tổ, who was raised in a pagoda. All of the kings during the Lý dynasty professed and sanctioned Buddhism as the state religion. This endured with the Trần dynasty (1225–1400), but Buddhism had to share the stage with the emerging growth of Confucianism.
