Outbreak of the rebellion In May 66, violence erupted in the city of
Caesarea over a land dispute. Local Jews sought to buy land beside their synagogue from its Greek owner, but despite offering well above its value, he refused and built workshops that blocked access to the synagogue. Some young Jews tried to stop the construction, but Florus suppressed their actions. Prominent Jews then paid Florus eight
talents to halt the work, but after taking the money he failed to intervene. On
Shabbat, Judaism's weekly day of rest, a Greek desecrated the synagogue by sacrificing birds at the entrance, sparking violence between the communities. A Roman cavalry commander tried but failed to stop the violence, and when Jewish leaders complained to Florus, he had them arrested. Afterwards, Florus arrived in Jerusalem and seized 17 talents from the Temple treasury, claiming it was for "governmental purposes". Mass protests ensued, and crowds mocked him by passing around a basket to collect alms as if he were a beggar. When the
Sanhedrin—the Jewish high court—refused to surrender the offenders, Florus ordered his troops to sack the Upper Agora, a marketplace in Jerusalem's affluent Upper City, reportedly killing over 3,600 people. Among the victims were wealthy Jews of the
equestrian order, who, despite being
Roman citizens and exempt from such punishment, were not spared. His soldiers exceeded orders, looting and taking prisoners. Jewish princess
Berenice, who was visiting the city, pleaded for restraint but was threatened by
legionaries. A second massacre occurred when two
cohorts (cavalry squadrons) arrived in the city. The Jews went to greet them peacefully, but were met with silence. Some, angered by this, began insulting Florus, prompting the soldiers to charge and causing a stampede toward the
Antonia Fortress. Jewish fighters trapped Roman cohorts with rooftop attacks, forcing them to retreat to Herod's palace, while rebels destroyed the porticoes linking the Temple to the Antonia to block Roman access and protect the Temple treasures. Florus fled the city, leaving a cohort behind to serve as a garrison. of the
Temple Mount during the first century CE, with the
Second Temple in the center and the
Antonia Fortress to the upper right Agrippa II hurried from Alexandria to calm the unrest, while
Cestius Gallus, the Roman governor of Syria, sent an emissary who found Jerusalem loyal to Rome but opposed to Florus. Agrippa then delivered a public speech to the people of Jerusalem alongside his sister Berenice, acknowledging the failures of Roman administration but urging restraint. He argued that a small nation could not challenge the might of the Roman Empire. At first, the crowd agreed, reaffirming allegiance to the emperor. They restored damaged structures and paid the tax owed. When he urged patience with Florus until a new governor was appointed, the crowd turned on him, forcing him and Berenice to flee the city.
Eleazar ben Hanania, the Temple's captain and son of an ex-High Priest, convinced the priests to cease accepting offerings from foreigners. This act ended the practice of offering sacrifices on behalf of Rome and its emperor, which the Romans viewed as affirmations of loyalty to imperial rule. According to Josephus, this event marked the foundation of the war. Around this time, a faction of Sicarii led by
Menahem ben Judah, a descendant of Judas of Galilee, launched a surprise assault on the desert fortress of
Masada, capturing it and killing the Roman garrison. The seized weapons were transported to Jerusalem. After failing to
pacify the rebels, Jerusalem's moderate leaders sought military assistance from Florus and Agrippa. In response, Agrippa dispatched 2,000 cavalrymen from
Auranitis,
Batanaea, and
Trachonitis. These forces reinforced the moderates, who controlled the Upper City, while Eleazar ben Hanania's followers controlled the Lower City and
Temple Mount. During the Jewish wood-gathering festival of
Tu B'Av (in August), several Sicarii infiltrated the city and joined the rebellious faction. After several days of fighting, the rebels captured the Upper City, forcing the moderates to retreat into
Herod's Palace, while others fled or went into hiding. They burned the house of ex-High Priest
Ananias, the royal palaces, and the public archives, where debt records were kept, likely to win support from Jerusalem's poor. The rebels then captured the Antonia Fortress, seizing artillery and massacring the Roman garrison. With reinforcements from the Sicarii, they captured Herod's Palace, then agreed to a ceasefire with the moderates, but refused to make peace with the Roman soldiers. The Romans retreated to the towers of Phasael, Hippicus, and Mariamne, where they held out for eleven more days. During this time, the Sicarii captured and killed Ananias and his brother. In mid-September, the besieged soldiers surrendered for safe passage, but the rebels killed them all except commander Metilius, who
pledged to convert to Judaism and undergo
circumcision. Menahem appeared in royal attire in public, but he was soon captured, tortured, and executed by Eleazar ben Hanania's faction; many of his Sicarii followers were killed or scattered. Others, including Menahem's relative Eleazar ben Yair, withdrew to Masada. Ethnic violence spread across the region. Around the time of the garrison massacre, according to Josephus, non-Jews in Caesarea carried out an ethnic cleansing, killing about 20,000 Jews. The survivors were arrested by Florus. Hundreds of Jews were reportedly killed in
Ascalon and
Akko-Ptolemais; in
Tyre,
Hippos, and
Gadara, many were executed or imprisoned. The Jews of
Scythopolis initially assisted their fellow townspeople in defending the city from Jewish attackers. However, they were later relocated with their families to a grove outside the town, where they were killed by those who had fought alongside them. In
Antioch,
Sidon, and
Apamea, the local residents spared the Jewish communities, and in
Gerasa, they even escorted those who chose to leave all the way to the city's border. Upon hearing of the massacre of Jews in Caesarea, Jewish groups launched attacks on nearby villages and cities, especially in the
Decapolis, including
Philadelphia,
Heshbon, Gerasa and
Pella.
Cedasa, Hippos, Akko-Ptolemais, Gaba, and Caesarea were also targeted. Archaeological evidence confirms destruction in Gerasa and Gadara. Josephus also describes Sebaste,
Ashkelon,
Anthedon, and
Gaza as destroyed by fire, although this may be an exaggeration. Violence also
broke out in Alexandria when Greeks attacked Jews, capturing some alive and provoking retaliation. Roman governor
Tiberius Julius Alexander—a Jew who had renounced his ancestral tradition—attempted mediation but failed, and his troops killed tens of thousands of Jews. In Judaea, Jewish forces seized the fortresses of Cypros near
Jericho and
Machaerus in Perea.
Gallus' campaign and defeat At this point, Gallus marched from Antioch to Judaea with
Legio XII Fulminata, 2,000 troops from each of Syria's three other
legions, six infantry cohorts, and four cavalry units. Vassal kings
Antiochus IV of Commagene, Agrippa II, and
Sohaemus of Emesa sent thousands of cavalry and infantry to reinforce his army. Irregular forces from cities like
Berytus, driven by anti-Jewish sentiment, were also recruited. From his base in Akko-Ptolemais, Gallus launched a campaign in Galilee, burning
Chabulon and nearby villages before marching to Caesarea. His forces captured
Jaffa, killed its people, and torched the city. Cavalry units were also dispatched to ravage the
toparchy (district) of Narbata, near Caesarea. The residents of
Sepphoris welcomed the Romans and pledged their support. Gallus then advanced toward Jerusalem, leaving destruction in his wake. The town of
Lydda, largely deserted as most residents had gone to Jerusalem for the religious festival of
Sukkot (around September–October), was destroyed, and those who remained were killed. As the army continued through
Bethoron and
Gabaon, it was ambushed by Jewish forces, suffering heavy losses. Among the Jewish fighters were
Niger the Perean Simon bar Giora, and
Adiabenian princes Monobazus and Candaios. Agrippa made a final attempt at peace, but failed. In late
Tishrei (September/October), Gallus encamped on
Mount Scopus overlooking Jerusalem. This drove the rebels into the inner city and Temple complex. Upon entering, Gallus set fire to the
Bezetha district and Timber Market to intimidate the population. For unclear reasons, he lifted the siege and retreated. Josephus suggested that Gallus could have captured the city with more determination. Historian
Menahem Stern suggested that Gallus, facing strong resistance, doubted he could seize the city. Historian
E. Mary Smallwood proposed that Gallus may have been concerned about the approaching winter, lack of siege equipment, the risk of ambushes in the hills, and the potential insincerity of the moderates' offer to open the gates. Gallus' retreat turned into a rout, resulting in the loss of 5,300 infantry and 480 cavalry. At the steep, narrow Bethoron pass, the Roman force
fell into an ambush by archers positioned on the surrounding cliffs. Some escaped under cover of darkness but at the cost of hundreds of men. Pursued to
Antipatris, the Roman forces abandoned supplies, including artillery and battering rams, which the rebels seized.
Suetonius claimed the Romans lost their
legionary eagle. Gallus died soon after, possibly by suicide. Scholars note the rarity of this defeat as a decisive Roman loss in a provincial uprising. The unexpected victory boosted pro-revolt factions, increasing their confidence, and many others were swept up in the enthusiasm. Some elite moderates fled to the Romans; others stayed and joined the rebels. Among those fleeing were Costobar and Saul, members of the Herodian royalty, as well as Philip, son of Iacimus, the prefect of Agrippa's army. Around the same time, a pogrom broke out in
Damascus. The city's men, fearing betrayal by their wives who had converted to Judaism, locked the Jewish population in a
gymnasium and, according to Josephus, killed thousands within hours.
Judean provisional government . Obverse: "
Shekel, Israel. Year 3." Reverse: "Jerusalem the Holy"|alt=A silver Jewish rebel coin with Paleo-Hebrew inscriptions on both sidesAfter Gallus' defeat, a popular assembly convened at the Jerusalem Temple and established a
provisional government.
Ananus ben Ananus, a former High Priest, was appointed as one of its leaders alongside
Joseph ben Gurion, a
Pharisee, and other members of the city's priestly elite, including
Joshua ben Gamla. The new government divided the country into military districts. Josephus was appointed commander of Galilee and
Gaulanitis, while Joseph ben Shimon commanded Jericho. John the Essene led the districts of Jaffa, Lydda,
Emmaus, and
Thamna, and Eleazar ben Ananias and Jesus ben Sappha oversaw
Idumaea, with Niger the Perean, a hero of the Gallus campaign, under their command. Menasseh commanded Perea in
Transjordan, and John ben Ananias was tasked with
Gophna and
Acrabetta. Eleazar ben Simon, who had played a role in Gallus' defeat and seized large amounts of money and spoils, was denied any formal position. Simon bar Giora, another leading figure in the victory over Gallus, was likewise overlooked. Citing the exclusion of the Zealots, scholars such as
Richard Horsley argued that the government may have only feigned support for the revolt, instead seeking a compromise with Rome. Following the Temple meeting, Jerusalem's priestly leadership began
minting coins—an assertion of financial autonomy and rejection of foreign rule. The coins bore Hebrew inscriptions with slogans like
"Jerusalem the Holy" and
"For the Freedom of Zion", later changed in the fourth year to
"For the Redemption of Zion". Dated using a new revolutionary calendar (years one to five), they marked the start of a new era of independence. The silver coins—the first of their kind in Jewish history—were labeled as the
"shekel of Israel", "Israel" possibly denoting the state's name. Their denominations (
shekel,
half-shekel,
quarter-shekel)'''' revived the biblical weight system, evoking ancient sovereignty, and the use of Hebrew symbolized Jewish nationalism and statehood. The new government ordered the destruction of Herod Antipas' palace in
Tiberias due to its display of images forbidden by Jewish law, possibly to demonstrate zeal or appease rebels. Envoys were sent to Jews in the Parthian Empire to seek support against Rome. In Jerusalem, the unfinished Third Wall protecting the northern flank was completed. With no regular army since the Hasmoneans, the government struggled to build one, as most military-age men had joined rebel factions. Rebels acquired arms by stripping the dead and captured, raiding fortresses, commissioning local blacksmiths in Jerusalem, and possibly buying from suppliers connected to the Roman army. During
Hanukkah, the Jewish festival commemorating the recovery of Jerusalem in the Maccabean revolt, Niger the Perean and John the Essene led an assault on Ashkelon, a city that remained under Roman control. Two successive attacks were repelled, forcing a retreat. The provisional government lacked broad support, and rival factions soon formed. Some rallied around distinct ideologies, others around charismatic leaders, and they turned their weapons not only against Rome but also against each other. In Galilee,
John of Gischala, a wealthy olive oil trader, emerged as a key rebel leader. Initially opposed to the war, he changed his stance after his hometown
Gush Halav was attacked by the people of Tyre and Gadara. Leading a group of peasants, refugees, and brigands, he became Josephus' main adversary, but failed to displace him. Meanwhile, Simon bar Giora led attacks on the wealthy in northern Judea. Expelled from Acrabetene, he fled to Masada, where rebels first distrusted but later accepted him into their raids. ==Vespasian's campaigns==
