The persecution of Jews didn’t start with the Romans; the Greeks’ dislike began during the Persian Empire, perhaps in part because the Jews considered Cyrus the Great a liberator and the Greeks not so much. Like the Romans, the Greeks scoffed about the lack of idols in the Temple, and regarded circumcision as mutilation.
The Romans couldn’t get Jews to serve in the army; their reluctance to serve was an obvious consequence of their food laws and the Shomer Shabbat, which prohibits even cooking food on the sabbath. In exchange for the Roman occupation and the continual tension with the Parthians, and not having to serve in the occupying power’s army, the Jews were given the favor of paying a special tax.
After the Romans’ destruction of the Temple, the empire imposed the Fiscus Judaicus, a special tax mimicking the former tithing that Jews paid to support the Temple (now destroyed), that was levied on all Jews throughout the Empire (not merely Jews who had survived the revolt) to support the temple of Jupiter Capitolinus, the center of the most important official Roman cult. Sez here that temple burned down three times in a little over a century and a half, with the fourth iteration being built by, of course, Titus.
The Kitos War was one of the rebellions that festered out of the Roman atrocities. The immediate incitement came from the emperor Hadrian, the lover of catamites. He was especially appalled by circumcision and insulted by the Jews’ “failure” to adopt foreign cults. He decided to level what was left of Jerusalem and build a new city, dedicated to himself.
The Roman response to the uprisings was to massacre or enslave the population of Judea, and ban the practice of Judaism and circumcision throughout the empire. The bans lasted until that monstrous faggot Hadrian died.

You can read in the biblical book of Maccabees
[1] Now it came to pass, after that Alexander the son of Philip the Macedonian, who first reigned in Greece, coming out of the land of Cethim, had overthrown Darius king of the Persians and Medes: [2] He fought many battles, and took the strong holds of all, and slew the kings of the earth: [3] And he went through even to the ends of the earth, and took the spoils of many nations: and the earth was quiet before him. [4] And he gathered a power, and a very strong army: and his heart was exalted and lifted up. [5] And he subdued countries of nations, and princes: and they became tributaries to him.

[21] And after Antiochus had ravaged Egypt in the hundred and forty-third year, he returned and went up against Israel. [22] And he went up to Jerusalem with a great multitude. [23] And he proudly entered into the sanctuary, and took away the golden altar, and the candlestick of light, and all the vessels thereof, and the table of proposition, and the pouring vessels, and the vials, and the little mortars of gold, and the veil, and the crowns, and the golden ornament that was before the temple: and he broke them all in pieces. [24] And he took the silver and gold, and the precious vessels: and he took the hidden treasures which he found: and when he had taken all away he departed into his own country. [25] And he made a great slaughter of men, and spoke very proudly.

[46] And the king sent letters by the hands of messengers to Jerusalem, and to all the cities of Juda: that they should follow the law of the nations of the earth, [47] And should forbid holocausts and sacrifices, and atonements to be made in the temple of God. [48] And should prohibit the sabbath, and the festival days, to be celebrated. [49] And he commanded the holy places to be profaned, and the holy people of Israel. [50] And he commanded altars to be built, and temples, and idols, and swine's flesh to be immolated, and unclean beasts. [51] And that they should leave their children uncircumcised, and let their souls be defiled with all uncleannesses, and abominations, to the end that they should forget the law, and should change all the justifications of God. [52] And that whosoever would not do according to the word of king Antiochus should be put to death. [53] According to all these words he wrote to his whole kingdom, and he appointed rulers over the people that should force them to do these things. [54] And they commanded the cities of Juda to sacrifice. [55] Then many of the people were gathered to them that had forsaken the law of the Lord: and they committed evils in the land:
I always thought that if there had been a second Trajan, a lot of the problems of the 2nd century would not have happened.
