As political scientist Dr. Ariel Hernandez documented, one example is the Philippines, where successive presidential administrations—at least since Ferdinand Marcos secured power in 1965—have "franchised violence to regional warlords" to counter the inroads of communist insurgents, Islamic rebels and organized criminal gangs. This has led to the formation of at least 93 "Partisan Armed Groups", armed militias loyal to regional warlords who, in exchange for their loyalty and willingness to use their private armies to quell the threats from these opposition groups, are granted a degree of autonomy within designated regions, the exclusive right to use violence and the right "to profit from the 'economy of violence' that they establish in their own areas".
