Final answer:
Within Judaism during Jesus' time, the Essenes and Zealots were two less influential groups compared to the Sadducees and Pharisees. The Essenes lived ascetically and were mysticists, while the Zealots were anti-Roman revolutionaries advocating for armed revolt.
Step-by-step explanation:
The two less important religious groups within Judaism in Jesus' day were the Essenes and the Zealots. The Essenes were known for their ascetic lifestyle and mysticism, living in the deserts outside major cities. Alternatively, the Zealots were a revolutionary group that advocated for armed revolt against the Roman occupiers of Palestine.
In contrast to the question referenced about the 1492 edict, which pertained to Jews and Muslims being forced to convert or leave Spain, these Jewish sects during Jesus' time focused on different aspects of religious and political life. The Sadducees and Pharisees were the more dominant religious factions, with distinct views on the adherence to laws and the coming of a messiah, but neither the Sadducees nor the Pharisees are mentioned in the provided options pertaining to the 1492 edict.
