Additionally Rome was successful in its goals, often, as a result of its incredible military. Many people assume it was due to greater weapons, armor, or numbers, but there are many instances of outnumbered legions winning against great odds. Many times the numbers, the weapons, the armor were not unequal, the source of inequality was found in the leadership. Rome had over its existence a great many military minds that stood out as brilliant, and better than almost any others who fought against them. Rome did, also, have a number bad leaders. But, the expansion of the borders of the empire happened most often under the reins of the best leaders, and at times the fall of Rome was averted solely by the military genius of another Roman military genius. They were not the only geniuses, and many times geniuses were wasted. But between political genius, military genius, great systems, and opportunity, Rome rose to be the greatest empire humans have known.
54 BC JULIUS CAESAR's LEGIONS invade Britain
One of the bold humans who revolted against the entity that was Rome, was Boudicca. Her story has been told many places, and many times, by me as well. Her husband was king, who upon death had his realm stolen by Rome. His wife was publicly flogged. Her daughters raped. Her tribe was the Iceni and they rebelled against the Romans, and followed Boudicca's call to revolt!
They burned London
They burned Camulodunum
They burned Verulamium
80,000 Romans and allies were slain.
And then Rome called up new Legions. Many revolts against empires fail, and the Iceni revolt was no different, and failed.
