The Army of the Roman Republic

From the moment its last king was expelled (traditionally in 753) the Roman republic had to fight for its very survival. Centuries of almost continuous warfare saw Romes armies evolve in response to a wide variety of threats which were met with mixed fortunes though always with ultimate success. As defence of the homeland turned to territorial expansion, Roman forces also had to adapt to sustained campaigns in varied terrain and climates, not to mention the changes in the Roman republic itself.
