Clone Troopers were created by the cloners on Kamino under the direction of Jedi Master Sifo Dyas ten years prior to the Clone Wars. Their genetic template, recruited by Count Dooku, was taken from the Mandalorian mercenary Jango Fett, who requested an unaltered clone as part of his payment (this clone would later become the legendary bounty hunter Boba Fett). Their existence was unknown to the Republic and the Jedi Order prior to the Clone Wars, until Jedi Master Obi-Wan Kenobi learned of them during his investigation of the assassination attempt against Naboo Senator Padme Amidala. These growth-accelerated clones were bred as soldiers from birth, spending their early lives utterly immersed in military training, and were said to be superior to battle droids in most respects. Loyalty to the Republic, and the Chancellor, formed a key part of their psyche.
