The Romans always had a very reasonable attitude towards the populations they conquered, allowing trade, religion, traditional ceremonies and all other aspects of life to continue just as before they took over control. The exception was when they considered anything or anyone a threat to their own power - this included any resistance movements such as the "sicarii" in Jerusalem.
Jesus became considered a threat to Roman control because they understood He led a rebellious group and proclaimed Himself a King of the Jews (He did not, but that was the Roman understanding). The Romans thought that the Jews awaited a Messiah who would lead an uprising to throw out the Romans and believed that Jesus was that political leader.
They were led by leaders who opposed democracy.
Several Roman leaders opposed Octavian. Marc Antony opposed him from day one. Yes, they were triumvirates together but that was a compromise deal in which each man was basically out for himself. Cicero was another opponent of Octavian, along with Sextus Pompey and his fellow triumvir Lepidus.
Jesus was brought from Caiaphas' house to appear before Pontius Pilate, the Roman governor of Judea. The Jewish leaders charged Jesus with subversion of both Israel and Rome. Two of their charges were designed especially to get Pilate's attention. The first was that Jesus opposed paying taxes to Caesar and that Jesus claimed to be king. Finding no fault in Him, Pilate summoned Jesus into Herod's palace and questioned Him further. In the course of the conversation, Pilate learned Jesus was a Galilean and was under Herod's jurisdiction. So Pilate sent Jesus to Herod, who had heard about Jesus and wanted to see Him. Herod had Jesus dressed in a robe and sent back to Pilate. When Jesus came back, Pilate told the Jewish leaders that neither he nor Herod could find Jesus guilty of a crime that brought with it the death penalty.
Roman governor Pilate ordered the cruciffication of Jesus.
The group that opposed Paul the most was often the Jewish religious leaders, particularly the Pharisees and Sadducees. They viewed his teachings about Jesus as a threat to their authority and the Jewish law. Additionally, some Gentile groups and local authorities in various cities also opposed him, leading to conflicts and persecutions during his missionary journeys.
At the crucifixion of Jesus, those present included Roman soldiers, religious leaders, and some of Jesus' followers, such as Mary, the mother of Jesus, and Mary Magdalene.
The Roman authorities saw Jesus as a potential threat to their power and authority, especially after he was hailed as the King of the Jews. They also yielded to pressure from Jewish religious leaders who viewed Jesus as a blasphemer. Jesus' teachings and growing popularity created unrest among the people that the authorities wanted to quell.
The Sadducees opposed Jesus, they were the Temple , priestly group. He was also opposed by some of the Pharisees who were the faction which represented the Lay folk.
Only a roman ruler could legally order an execution, which is what the Jewish leaders wanted.

If you are referring to those who opposed Jesus during his lifetime, it was the Sadduccees, the Pharisees, and their ruling authority, the Sanhedrin.All of them belonged to the conquered Jewish theocracy answerable to the Roman Empire.
It is important to understand what the political climate was in the first century. Rome was the first and last word on all things. Pontius Pilate was there as the long arm of the Roman Empire, ordered to keep peace among the locals. Jesus upset the Jewish leaders and Rabbis, not so much the Roman leaders in the area. But the Jewish leaders used their influence and the threat of civil unrest to provoke the Romans to put Jesus to death.
Jesus knew the Jewish scriptures well but seemed to contradict what they thought was the Law. Jesus challenged their interpretation of the Law.
Several Roman leaders opposed Octavian. Marc Antony opposed him from day one. Yes, they were triumvirates together but that was a compromise deal in which each man was basically out for himself. Cicero was another opponent of Octavian, along with Sextus Pompey and his fellow triumvir Lepidus.
Christ had to be condemned to death by Pilate, the Roman governor, because the Jewish leaders did not have legal authority under Roman law to condemn a criminal to death.
