Most were the Pharisees and Saduccees. These were religious officials who had taken God's Laws and added their own over generations so that the Law had become cumbersome and dogmatic. They also wielded great power and insisted on others' deference to them and their exemption from many of the laws which they imposed on others.
By exploiting the poor and the weak they grew in power, and questioned Jesus incessantly trying to trip him up so that he could then be charged with 'blasphemy'. However, Jesus treated their beliefs rightly with contempt, calling them hypocrites and vipers.
It was as a result of these two groups that Jesus was finally executed, and they believed then to have had the victory. However, after the resurrection of Jesus, these officials eventually went into obscurity and disappeared, whilst the Christian Cghurch is now 2 and a half billion strong worldwide.
They were the pharasees.

The Pharisees which were Jewish religious leaders
When Jesus refers to the religious leaders as a "brood of vipers" in the Bible, he is criticizing them for being deceitful and hypocritical, comparing them to venomous snakes that are dangerous and harmful. Jesus is highlighting their dishonesty and lack of true righteousness.
Since Jesus is the son of God, He would be king of the Jews. Him being a king would make him a threat to King Ceaser, and the religious leaders feared that they would lose their positions.
They falsely charged Jesus of blasphemy. Mark 14:64
