In the single campaigning season of 146 BC, the Roman Republic razed Carthage and Corinth, demonstrating to the Mediterranean basin that supervisory hegemony had been permanently replaced by categorical erasure.

INFOGRAPHIC DESIGN BRIEF: IV-G02 — THE YEAR 146

Compendium Volume: Book IV — The Wars of Mediterranean Hegemony (200–146 BC)
Asset Identifier: IV-G02
Format / Canvas: 16:9 Panoramic Plate
Target Register: Military-cartographic staff-history display; high-density editorial museum presentation. Clean, precise, devoid of romantic mysticism.

1. Purpose & Thesis

This plate illustrates the defining geopolitical watershed of the mid-second century BC: the simultaneous destruction of Carthage (African coast) and Corinth (central Greece) within a single campaigning season in 146 BC. By physically annihilating the two commercial and political alternatives to Roman dominance, the Republic replaced fifty years of supervisory client-management with categorical, programmatic erasure. The center vertical pillar anchors the plate in historical consciousness through the eyewitness account of Polybius of Megalopolis and the philosophical weeping of Scipio Aemilianus over the burning ruins.
