Several significant administrative achievements were made during the Hōjō regency. In 1225 the third regent Hōjō Yasutoki established the Council of State, providing opportunities for other military lords to exercise judicial and legislative authority at Kamakura. The Hōjō regent presided over the council, which was a successful form of collective leadership. The adoption of Japan's first military code of law—the Goseibai Shikimoku—in 1232 reflected the profound transition from court to militarized society. While legal practices in Kyoto were still based on 500-year-old Confucian principles, the new code was a highly legalistic document that stressed the duties of stewards and constables, provided means for settling land disputes, and established rules governing inheritances. It was clear and concise, stipulated punishments for violators of its conditions, and remained in effect for the next 635 years.
