5.1 Purging disloyalty
'Divide and Conquer' in Caesar's Gallic Wars - 'Vercingetorix Throws Down His Arms at the Feet of Julius Caesar', 1899 painting by Lionel Noel Royer.
The political strategy of dividing one’s enemies in order to secure power is tried and proven. Compared with a united and focused force; fragmented, smaller enemies made to become suspicious of each other, are distracted and weakened. The Latin origin ‘divide ut regnes’ is indeed ancient and can at least be traced back to Julius Caesar picking off his enemies by siding with individual tribes in disputes with their local rivals.
