In 142 CE Zhang Daoling announced that Laozi had appeared to him and commanded him to rid the world of decadence and establish a new state consisting only of the ‘chosen people.’ Zhang became the first Celestial Master, and began to spread his newly founded movement throughout the province of Sichuan. The movement was initially called the "Way of the Five Pecks of Rice", because each person wishing to join was required to donate five pecks of rice. The movement spread rapidly, particularly under his son and grandson Zhang Lu. Their rebellion against the Han dynasty is known as the Five Pecks of Rice Rebellion. After the success of the rebellion in 194, they founded the theocratic state of Zhang Han in the Hanzhong Valley of Sichuan, enjoying full independence.
