The 50th Law - Hardcover Book / Gold edged pages

The book The 50th Law grew out of the friendship and mutual admiration between 50 Cent and Robert Greene. Greene's book The 48 Laws of Power, which has long been a staple in the hip hop world, came to the attention of 50, who asked his manager to set up a meeting. Greene has said he was surprised by 50's persona and was impressed by his "zen-like calmness" and eye for strategy. The two began to work on a book project that would combine their two worlds.

According to Greene, 50 is an example of what Machiavelli called a New Prince, a leader who emerges in a time of chaos or turmoil and rewrites the rules. According to 50, Greene's books describe the laws and strategies used by hustlers on the street, even if they might not know the "technical terms" for what they were doing.
