During the first and second centuries A.D., the supremacy of the Roman Empire was aggressively challenged by three Jewish rebellions. The facts surrounding the initial uprising of A.D. 66-74 have been filtered through the biased accounts of Judeao-Roman historian Flavius Josephus. Primary information regarding the subsequent Diaspora Revolt (A.D. 115-117) and the Bar Kochba Rebellion (A.D. 132-135) is limited to fragmentary anecdotes emphasizing the religious implications of the two insurrections.
