History of the Jews in the Roman Empire in the context of "Early centers of Christianity"

Early Christianity, otherwise called the Early Church, describes the historical era of the Christian religion up to the First Council of Nicaea in 325. Christianity spread from the Levant, across the Roman Empire, and beyond. Originally, this progression was closely connected to already established Jewish centers in the Holy Land and the Jewish diaspora throughout the Eastern Mediterranean. The first followers of Christianity were Jews who had converted to the faith, i.e. Jewish Christians, as well as Phoenicians, i.e. Lebanese Christians. Early Christianity contains the Apostolic Age and is followed by, and substantially overlaps with, the Patristic era.

The Apostolic sees claim to have been founded by one or more of the apostles of Jesus, who are said to have dispersed from Jerusalem sometime after the crucifixion of Jesus, c. 26–33, perhaps following the Great Commission. Early Christians gathered in small private houses, known as house churches, but a city's whole Christian community would also be called a "church"—the Greek noun ἐκκλησία (ekklesia) literally means "assembly", "gathering", or "congregation" but is translated as "church" in most English translations of the New Testament.

John the Baptist (c. 6 BC – c. AD 30) was a Jewish preacher active in the area of the Jordan River in the early first century AD. He is also known as Saint John the Forerunner in Eastern Orthodoxy and Oriental Orthodoxy, Saint John the Immerser in the Baptist tradition, and as the prophet Yahya ibn Zakariya in Islam. He is sometimes referred to as John the Baptiser.

John is mentioned by the Roman Jewish historian Josephus, and he is revered as a major religious figure in Christianity, Islam, the Baháʼí Faith, the Druze faith, and Mandaeism; in the last of these he is considered to be the final and most vital prophet. He is considered to be a prophet of God by all of the aforementioned faiths, and is honoured as a saint in many Christian denominations. According to the New Testament, John anticipated a messianic figure greater than himself; in the Gospels, he is portrayed as the precursor or forerunner of Jesus. According to the Gospel of Matthew, Jesus himself identifies John as "Elijah who is to come", which is a direct reference to the Book of Malachi (Malachi 4:5), as confirmed by the angel Gabriel, who announced John's birth to his father Zechariah. According to the Gospel of Luke, John and Jesus were relatives.

Herod I or Herod the Great (c. 72 – c. 4 BCE) was a Roman Jewish client king of the Herodian kingdom of Judea. He is known for his colossal building projects. Among these works are the rebuilding of the Second Temple in Jerusalem and the expansion of its base—the Western Wall being part of it. Many of the crucial details of his life are recorded in the works of the 1st century CE Roman–Jewish historian Josephus.

Despite Herod's successes, including forging a new aristocracy, he has been criticized by various historians. His reign polarizes historians’ opinions, some viewing his legacy as evidence of success, and some viewing it as evidence of tyranny.

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 (27 BCE), although Alexandrian Jews had already migrated to Rome, and some Gentiles had undergone Judaization on a 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. These actions shattered Jewish life in Iberia and saw mass migration of Sephardic Jews to escape religious persecution. Many resettled in the Netherlands and re-judaized, starting in the late sixteenth and early seventeenth centuries. In the religiously tolerant, Protestant Dutch Republic Amsterdam prospered economically and as a center of Jewish cultural life, the "Dutch Jerusalem". Ashkenazi Jews lived in communities under continuous rabbinic authority. In Europe Jewish communities were largely self-governing autonomous under Christian rulers, usually with restrictions on residence and economic activities. In Poland, from 1264 (from 1569 also in Lithuania as part of the Polish–Lithuanian Commonwealth), under the Statute of Kalisz until the partitions of the Polish–Lithuanian Commonwealth in 1795, Jews were guaranteed legal rights and privileges. The law in Poland after 1264 (in the Polish–Lithuanian Commonwealth in consequence) toward Jews was one of the most inclusive in Europe. The French Revolution removed legal restrictions on Jews, making them full citizens. Napoleon implemented Jewish emancipation as his armies conquered much of Europe. Emancipation often brought more opportunities for Jews and many integrated into larger European society and became more secular rather than remaining in cohesive Jewish communities.

Flavius Josephus (born Yosef ben Mattityahu; c. AD 37 – c. 100) was a Roman–Jewish historian and military leader. Best known for writing The Jewish War, he was born in Jerusalem—then part of the Roman province of Judea—to a father of priestly descent and a mother who claimed Hasmonean royal ancestry.

He initially fought against the Roman Empire during the First Jewish–Roman War as general of the Jewish forces in Galilee, until surrendering in AD 67 to the Roman army led by Vespasian after the six-week siege of Yodfat. Josephus claimed the Jewish messianic prophecies that initiated the First Jewish–Roman War made reference to Vespasian becoming Roman emperor. In response, Vespasian decided to keep him as a slave and presumably interpreter. After Vespasian became emperor in AD 69, he granted Josephus his freedom, at which time Josephus assumed the Emperor's family name of Flavius.

The fiscus Iudaicus or fiscus Judaicus (Latin for 'Jewish tax') was a tax imposed on Jews in the Roman Empire after the destruction of Jerusalem and its Temple in AD 70.

The fiscus Iudaicus replaced the traditional half-shekel Temple tax which had been paid annually by Jews for the maintenance of the Temple in Jerusalem. The new tax redirected those funds to the reconstruction of the Temple of Jupiter Optimus Maximus in Rome, which had been destroyed during the Year of the Four Emperors. The redirection of these funds represented a significant humiliation for the Jewish population of the empire. The tax continued even after the Capitoline Temple was rebuilt, contributing to Roman finances and also serving as a deterrent against proselytism and conversion to Judaism.
