Yuki Hideyasu, Ieyasu's second son, was sent as a hostage to Toyotomi Hideyoshi as a condition of peace in 1585. He was later adopted by the Shimofusa Yuki clan, and after Sekigahara (1600) received the large domain of Echizen Kitanosho (later Fukui) at 670,000 koku. Hideyasu was a man of outstanding martial ability but contracted syphilis and died at age 33 in 1607. As the founder of the Echizen Matsudaira clan, the line continued as the 'Go-Renshi'—second only to the three great Tokugawa branch houses—through the Meiji Restoration. In the late Edo period, Matsudaira Shungaku (Yoshinaga) was renowned as a great lord, and the Echizen Matsudaira line carried considerable prestige.
