1. 2Pac now calls himself Makaveli... Machiavelli was an Italian war strategist who advocated faking one's death to fool their enemies... 2Pac was a fan of his and had read his books several times. Perhaps 2Pac is taking his advice...
(But that is not all Machiavelli did... Nicolo Machiavelli was a political, military theorist, historian, playwright, diplomat, and military planner. He is well known today. Some of his works are "The Prince" (1513), and The Art of War (1521). NOTE: Bone Thugs 'N' Harmony's new double album which features 2Pac rather Makaveli is called just that. "The Art Of War". Coincedence Or Not???)
The art of war was written by Sun Tzu...

Edit: Nevermind I guess he wasn't the only one to write it... but Sun Tzu wrote it around 500 B.C. Oh well.
