It is quite true that during these two centuries we meet with frequent trouble on the borders and with one or two local revolts of more or less strength. At our chosen date the Jews were being stirred by their fanatical or "zealot" party into an almost hopeless insurrection; within two years the rebellion broke out. Three years later still, certain ambitious semi-Romans took advantage of a troubled time to make a determined but futile effort to form a Gaulish or German-Gaulish empire of their own. Half a century after Nero the Jews once again rose, but were speedily suppressed. But apart from these abortive efforts--made, one by a unique form of religious zeal, one by adventurous ambition, at opposite extremities of the Roman world--there was established a general, and in most cases a willing, acceptance of the situation and a proper recognition of its benefits. The only serious war to be feared within the empire itself was a civil war, begun by some aspiring leader when his chance seemed strong of ousting the existing emperor or of succeeding to his throne. Four years from the date at which we have placed ourselves such a war actually did break out. Nero was driven from the throne in favour of Galba, and the history of the year following is the history of Otho murdering Galba, Vitellius overthrowing Otho, and Vespasian in his turn overthrowing Vitellius. Yet all this is but the story of one entirely exceptional year, the famous "year of four emperors." Take out that year from the imperial history; count a hundred years before and more than a hundred years after, and it would be impossible to find in the history of the world any period at which peace, and probably contentment, was so widely and continuously spread. Think of all the countries which have just been enumerated as lying within the Roman border; then imagine that, with the exception of one year of general commotion, two or three provincial and local revolts, and occasional irruptions and retaliations upon the frontier, they have all been free from war and its havoc ever since the year 1700. In our year of grace 64, although the throne is occupied by a vicious emperor suffering from megalomania and enormous self-conceit, the empire is in full enjoyment of its _pax Romana_.
