3. Murietta belonged to a gang known as the Five Joaquins, who were notorious bandits during the height of the California Gold Rush. While Murietta's criminal activity likely did not have any political undertones, he nonetheless became a symbol of Mexican resistance as American settlers ventured to California. Unfortunately for him, this pushed the government to put a bounty on his head, leading to his murder and beheading. Luckily, Banderas's character didn't fall to the same fate.
