who did the roman army fight and why?

Answer 1

you'l have to be much clearer than that

Answer 2

The Roman army fought peoples who were a threat to the security of the Republic/Emipre and its economic well-being; and to assert control over economic resources. On some occassions, such as in the case of the Third Punic War, the object of its aggression was on a percieved threat more than a real one, however. Some of the main rivals to Roman authority were: Etruscans, Italic-Greeks, and Samnites in Italy; Gauls, Iberians, and Germans in Western Europe; Thracians (including the Dacians), Illyrians, Greek cities, and Sarmatians in Eastern Europe; Seleucid Empire, Ptolemaic Empire, the Kingdom of Pontus, and the Parthian Empire in the Middle East; and the Carthaginians and Numidians in North Africa. This is by no means a comprehensive list, but it does give an idea of some of the greatest threats.

I should also mention that in some cases, the Roman army fought with itself. Civil wars of the first century B.C. saw Roman soldiers fighting against one another. Equally 69 A.D., 193, and most of the third century saw military civil war with armies under various warlords. The system was set up so that soldiers became loyal to their commander rather than the state or some higher cause, for the sake of wealth and land. When the opportunity rose for their commander to be Emperor, they saw a great opportunity to enrich themselves; and so they were willing to fight their fellow soldiers.

Answer 3

Huh? All depends on when.
The Romans fought, at various times, the Sabines, The Greeks, the other Romans (Caesar vs. Pompey, Antony vs. Octavian, etc.), the Hebrews, the Ptolemaic Egyptians, The Goths, Franks, Picts, Britons, Saxons, Visigoths, Huns, ..........
This was not unusual for the times. The world used to be a much, much bloodier place before the era of modern nation-states, with all their problems. That Roman fighting , by the way, all took place in a period of about 750 years.
