The Roman territory of Palestine was a thorn in the Rome’s' side, thanks to the unshakable opposition of the Jews. Palestine suffered from heavy taxation and deeply-felt resentment among its population toward the Romans. One key point of contention was that the Jews refused to pay lip service to the divinity of the emperors; the Romans insisted that their subjects participate in symbolic rituals acknowledging the primacy of the emperors. Since the Jews were strict monotheists, they would not do so. In 66 CE there was a huge uprising against Rome. It took four years for imperial forces to crush the uprising, resulting in the greatest disaster in ancient Jewish history: the permanent destruction of the Temple of Jerusalem in 70 CE. In the aftermath, the Romans enslaved or deported much of the Jewish population, which contributed the phenomenon of the Jewish diaspora, the people without a homeland united only by the Hebrew Bible, the teaching of the rabbis, and Jewish cultural traditions. Another uprising decades later (between 132 - 136 CE) resulted in the almost complete dispersal of the Jews, to the point that the Jewish homeland was truly lost to them until the foundation of the modern state of Israel in 1948 CE.
In the first century CE, Jewish society, especially its leadership, was divided between rival groups. Some powerful priests, the Sadducees, claimed that all Jews should follow the 10 Commandments, but only the priests of the Temple needed to follow the 613 laws and injunctions laid down by Moses. They were opposed by the Pharisees, who insisted that all Jews had to abide by all of the laws of Moses, and they also preached that a messiah - a savior - would soon come to bring about a day of judgment before Yahweh and bring about the fulfillment of the Biblical Covenant. In the deserts outside of the major cities, a group called the Essenes emphasized a life of asceticism and mysticism, while across Palestine anti-Roman revolutionaries known as the Zealots advocated for armed revolt against the Roman occupier.
The Jewish uprising that occurred against the Romans in 66 CE happened a generation after the death of another Jewish revolutionary of sorts: Jesus of Nazareth. The major source of information on the life of Jesus are the four gospels, accounts of his life and teachings composed after his death by three of his apostles (his closest followers and students), Matthew, Mark, and John, and another early Christian leader, Luke. The gospels were transmitted orally for decades before being recorded in their definitive versions; most scholars now date the written gospels to approximately 90 CE (about sixty years after the death of Jesus). While the specific language of the gospels is, of course, different, and some of the events described are also described differently, the gospels agree on most of the major aspects of the life of Jesus.
According to the gospels, Jesus was the son of the miraculous union of the Holy Spirit, one of the aspects of the Jewish God Yahweh, and a virgin named Mary. Jesus showed an aptitude for theological and spiritual understanding at a young age, debating Jewish doctrine with learned Jewish priests when he was still a boy. At the age of thirty, having earned his living as a carpenter up to that point, Jesus began to preach a message of salvation that revolved around the concept that mankind as a whole could be saved if it sought forgiveness from God for its sins. He traveled and delivered his teachings in the Roman province of Palestine and the nearby puppet kingdoms dominated by the Romans for three years, but was then arrested by the Roman authorities for inciting rebellion. In the end, Jesus was executed in the customary Roman fashion of crucifixion at the age of 33.
According to the gospels, Jesus returned to life, with an angel rolling the boulder back from the entrance to the tomb in which his body had been laid to rest. He renewed his call for devotion to God and the offer of salvation for those who sought forgiveness, then passed into the divine presence. Jesus's followers, led by the twelve apostles, began to teach his lessons to others, and the new religion of Christianity was born. His followers began to refer to Jesus as "the Christ," meaning "the anointed one" in Greek, a reference to the idea that Jesus was anointed to provide salvation for humanity.
