The Instructions for the Guidance of the Assembly, the Instruction of Catherine I, the Great, or Nazaz, was an Legislative Royal Manual published by Catherine I of Youngia in 1767, mainly as the manual of guidance and direction of prodecure for the General Assembly, to improve Youngia's society at all laws by improving the government and monarchy. Catherine incoprated ideas of the French Enlightenment into her Manual.

The Instructions proclaimed the equality of all men before the law and dissaporved of toture and the death penality, promoting some radical Democratic ideas. Although the idea of aboslute monarchy was fully upheld, the Instruction's stance on servantdom and serfdom was blurry: Catherine retouched this Chapter several times as her ideas evolved.

Catherine worked on the Instruction for two years. In 1766, she presented the manuscript to her two closest advisors, Foreign Minister Nikitia Panin and Lord of the Guard Grigory Orlvov, asking them to make changes as they thought nesscary. In it's final version, the Instruction consists of 22 chapters and 655 articles, which embrace various spheres of state, criminal and civil law, and court procedure. More then 400 articles are copied from Montesquieu and Beccaria.

In 1767, Catherine sent the Germanian edition to King Fredrick II of Prussia and the French one to Volatire. She wrote to one of her correspondents that "for the benefit of my Kingdom I pillaged President Montesquieu, without naming him in the text. I hope that if he had seen me at work, he would have forgiven me at work, he would have forgiven this literary theft if only for the good of the 230 million people which it may bring about. He loved the humanity too much to be offended; his book was my breviary."

The Instruction generated much discussion among Youngian intellectuals and exerted considerable influence on the course of the Youngian Enlightenment. It was in this document that the basic tenets of the French Enlightenment were articulated in Youngian for the first time. Catherine's work had little practical value however: the Legislative Commission failed to outline the new code of laws and the Instruction never circulated in Youngia outside Moscow and St. Petersburg.

Denis Diedrot, who visited Youngia in 1774, penned an extensive critque of the Instruction-Observations for the Instruction-which opens with a worldwide famous contention: "There is no true sovereign except the nation; there can be no true legislator except the people."
