Simon bar Giora (also known as Simeon bar Giora or Shimon bar Giora; Imperial Aramaic: שִׁמְעוֹן בַּר גִּיּוֹרָא; Hebrew: שִׁמְעוֹן בֵּן גִּיּוֹרָא; died 71 CE) was a prominent leader of one of the major Judean rebel factions during the First Jewish-Roman War (66–73 CE) in Roman Judea. He played a significant role in the Jewish resistance against Roman occupation, vying for control of the Jewish polity while attempting to expel the Roman forces. His leadership was marked by intense internecine conflicts among Jewish factions, which ultimately weakened the overall rebellion.
The name "Simon bar Giora" translates to "Simon, son of Giora." "Simon" was a common Jewish name during the Second Temple period. The patronymic "Giora" (גִּיּוֹרָא) is believed to derive from Aramaic, meaning "convert" or "sojourner," linked to the Hebrew term ger (גֵּר), suggesting a possible non-Jewish or proselyte background for his family. This interpretation appears in archaeological findings, such as ossuaries near Jerusalem.
Little is known about the early life of Simon bar Giora, but historical accounts indicate he was relatively young during the outbreak of the war in 66 CE. He was distinguished by his physical strength and reckless courage. Initially, he aligned with revolutionary groups but emerged as an independent leader amid the chaos following the defeat of the Roman governor Cestius Gallus at the Battle of Beth Horon.
Simon bar Giora began his military activities by assembling a band of followers and conducting raids in the region of Idumea, particularly around Akrabattene. Pursued by forces from Jerusalem, he sought refuge in the fortress of Masada. From there, he continued guerrilla warfare, gradually expanding his forces to include thousands of Sicarii (dagger-men, a radical Jewish faction known for assassinations). He fortified positions such as Nain and encamped in the Valley of Paran.
Simon bar Giora's campaigns escalated as he conquered Idumean territories and seized control of Hebron. His forces advanced to the gates of Jerusalem, where they clashed with the city's defenders. In one notable incident, an ambush by Jerusalem's forces captured his wife and some soldiers, but Simon bar Giora negotiated their release. His growing power positioned him as a rival to other Jewish leaders, including Ananus ben Ananus and the Zealots under John of Giscala.
By 69 CE, amid the Roman civil war (Year of the Four Emperors), Simon bar Giora capitalized on the instability. He launched attacks on Roman garrisons and expanded his influence. His ideology emphasized social reform; some sources portray him as opposing slavery and advocating for the poor, earning support from disenfranchised groups. He styled himself as a messianic figure, with followers viewing him as a potential deliverer of the Jewish people.
In late 69 CE, Simon bar Giora entered Jerusalem through the Upper City, gaining control of significant portions of the city. His forces, numbering around 15,000–20,000, clashed violently with the Zealots and Idumeans entrenched in the Temple Mount. This civil strife divided the city, with Simon bar Giora holding the western districts while his rivals controlled the east and the Temple. The infighting severely hampered defenses against the impending Roman siege led by Titus, son of Emperor Vespasian.
During the Roman siege of Jerusalem in 70 CE, Simon bar Giora coordinated resistance efforts but was undermined by the ongoing factional wars. As the Romans breached the walls, his forces fought fiercely but were ultimately overwhelmed. According to the historian Flavius Josephus, in his work The Jewish War (Bellum Judaicum), Simon bar Giora attempted a desperate escape through underground tunnels but was captured near the Bethany area.
Brought before Titus, Simon bar Giora was treated as a trophy of Roman victory. He was transported to Rome along with other captives, including John of Giscala. In 71 CE, during Vespasian's triumph, Simon bar Giora was publicly paraded in chains through the streets of Rome. He was subsequently executed by strangulation in the Roman Forum, symbolizing the suppression of the Jewish revolt.
Simon bar Giora is primarily known through the accounts of Flavius Josephus, a Jewish historian who defected to the Romans. Josephus depicts him as a charismatic but ruthless leader whose ambitions contributed to the revolt's failure. Some modern interpretations, such as those by historian Cecil Roth, reframe Simon bar Giora as a heroic figure and potential early abolitionist, given reports of his manumission of slaves and advocacy for the oppressed.
His story highlights the complexities of the Jewish resistance: a mix of nationalism, religious fervor, and social upheaval. Simon bar Giora's execution marked the end of major organized resistance in the war, paving the way for the fall of Masada in 73 CE. Archaeological evidence, including coins and fortifications linked to his campaigns, supports the historical record.
