This is a complete non sequitor. Jews didn't control anything for most of their history. Not in their native homeland, and not in Europe, either. The Romans conquered Judea and ruled over it; when the Jews rebelled, the Romans destroyed Jerusalem and their sacred temple. Then when Rome fell, the Byzantines continued to rule Judea. Then they were forced out by the Caliphate. So the Jews went from being subjects of Pagans, then Christians, then Muslims. A humiliating fate for 'gods chosen people'.

Jews were not allowed to hold any positions of power in Rome, and this tradition continued in Medieval Europe. In fact, Jews were forced to live in Ghettos where they would not cause trouble. Christians had an adversarial attitude towards the Jews because they clung to the traditions of the Pharisees, which was ridiculed in the Bible as heretical. It was not until the Enlightenment that attitudes towards the Jews began to soften, with disastrous consequences for Europe. As they drifted away from Christianity, they forgot why the Jews were put in the Ghettos. Then, with the French revolution, the Jews were released from the Ghettos, free to spread chaos.
