History of the Jews in Europe
The history of the Jews in Europe spans a period of over two thousand years. Jews, a Semitic people descending from the Judeans of Judea in the Southern Levant, began migrating to Europe just before the rise of the Roman Empire. Although Alexandrian Jews had already migrated to Rome, and with few Gentiles undergone Judaization in few occasions. A notable early event in the history of the Jews in the Roman Empire was the 63 BCE siege of Jerusalem, where Pompey had interfered in the Hasmonean civil war. Jews have had a significant presence in European cities and countries since the fall of the Roman Empire, including Italy, Spain, Portugal, France, the Netherlands, Germany, Poland, and Russia. In Spain and Portugal in the late fifteenth century, the monarchies forced Jews to either convert to Christianity or leave and they established offices of the Inquisition to enforce Catholic orthodoxy of converted Jews.
