The civil wars that destroyed the Roman Republic left their mark on Judaea, where Jewish leaders had taken sides in the conflict. The turmoil created a climate of violence throughout the area, and among the Jews, movements in opposition to the Romans spread. Some of these movements, such as the Zealots, encouraged armed rebellion against Roman rule, which would break out several times in the first and second centuries C.E. (see pages 156 and 155). Many Jews came to believe that a final struggle was near and that it would lead to the coming of a savior, or Messiah, who would destroy the Roman legions and inaugurate a period of peace, happiness, and prosperity for Jews. This apocalyptic belief was an old one among Jews, but by the first century C.E., it had become more widespread than ever, with many people prophesying the imminent coming of a Messiah and readying themselves for a cataclysmic battle.

The pagan world also played its part in the story of early Christianity. The term pagan, derived from a Latin word meaning “rural dweller,” came to refer to those who practiced religions other than Judaism or Christianity. This included religions devoted to the traditional Roman gods, syncretistic religions that blended Roman and indigenous deities, the cult of the emperor, and mystery religions that offered the promise of life after death (see "Religion and Magic" in Chapter 4). Many people in the Roman Empire practiced all of these, combining them in whatever way seemed most beneficial or satisfying to them.
