In Daniel 5:30, how could Belshazzar be slain “that very night” if some records suggest Babylon surrendered peacefully?

Historical Context

Babylon’s fall to the Medo-Persian Empire occurred around 539 BC. According to many ancient sources and modern historical research, the city of Babylon was immensely fortified, rich, and significant as a cultural center. Yet Daniel 5 describes a scene in which the Babylonian king at the time—Belshazzar—is feasting while the kingdom faces imminent threat, culminating in his death “that very night.” Some classical records (such as portions of the Nabonidus Chronicle and the so-called “Cyrus Cylinder”) suggest a relatively quick or even “peaceful” entrance by Persian forces. The question arises: If Babylon surrendered with minimal bloodshed, how can Daniel 5:30 say, “That very night Belshazzar king of the Chaldeans was slain”?

The Biblical Record (Daniel 5:30)

Daniel 5:30 plainly states: “That very night Belshazzar king of the Chaldeans was slain.” The wider narrative of Daniel 5 portrays a remarkable event: a feast interrupted by a supernatural handwriting on the wall. Daniel interprets the writing as God’s proclamation that Belshazzar’s kingdom is finished (Daniel 5:26–28). The text next affirms that judgment came swiftly on Belshazzar.

Ancient Accounts of Babylon’s Fall

1. Herodotus (Histories, Book 1) – Writing in the fifth century BC, Herodotus reports that the Persian king Cyrus managed to divert the Euphrates River, allowing his troops to enter under the city walls. Some accounts emphasize a degree of surprise rather than drawn-out warfare within the city, supporting the notion that the city did not endure a long siege.

2. Xenophon (Cyropaedia 7.5) – Xenophon similarly indicates that a strategic diversion of the river led to a largely unforeseen incursion, implying the city could have been taken without major external battle. However, details regarding the leadership within Babylon differ slightly among ancient sources.

3. Nabonidus Chronicle – This chronicle, which survives in fragments, indicates that the final transition of power involved confusion among Babylon’s leadership. Belshazzar is not mentioned by name in all fragments, but the father of Belshazzar, Nabonidus, was absent from the city for considerable periods.

4. Cyrus Cylinder – Often cited as an example of Persian propaganda, this artifact claims Cyrus took Babylon virtually without resistance, describing the event in terms favorable to Cyrus’s kingship. It does not, however, deny the possibility that key royal officials or the regent might have been overthrown or killed in the process.

Possible Explanations

1. Local Palace Resistance

Though the broader city surrendered with minimal resistance, Belshazzar and his retinue may have still defended the royal precinct. A swift, targeted takeover of the palace district could account for Belshazzar’s immediate death.

2. High-Profile Elimination

Even if the general population offered little or no resistance to Persian forces, toppling the ruling monarch was politically critical. Belshazzar, as co-regent or acting king, posed a threat to the new regime and may have been executed or killed in combat upon Cyrus’s entry.

3. Propaganda vs. Specific Event

Records emphasizing a “peaceful” surrender often served to bolster the victor’s image. The city’s populace might have cooperated with Cyrus, but that would not preclude a violent end for Belshazzar in the palace itself.

4. Biblical Accuracy in Kings’ Downfalls

Scripture often depicts decisive judgments on rulers at critical historical junctures (e.g., Pharaoh in the Exodus, Nebuchadnezzar’s humbling in Daniel 4). Belshazzar’s death “that very night” aligns with the repeated pattern of swift divine judgment, supported here by the fact that multiple outside sources confirm a sudden fall of Babylon’s leadership.

Archaeological and Historical Corroborations

Archaeological evidence shows the robust walls and defenses of Babylon could indeed have been bypassed through engineering feats along the Euphrates. Babylon’s massive gates, canals, and moats were vulnerable to a lowered river—an event that would allow portions of the Persian army to infiltrate.

Additionally, the British Museum’s collection of Babylonian Chronicles refers to internal strife and lack of detailed mention of a large-scale battle to capture the city’s interior. This omission highlights that, while the city did not necessarily endure a prolonged siege or wholesale destruction, there was a regime change that removed the reigning authority.

Strategic and Theological Considerations

Belshazzar’s focus on revelry during a perilous time (Daniel 5:1) strongly suggests he was overconfident. From a theological perspective, the sudden nature of his demise underscores the biblical principle that human pride is swiftly judged (cf. Proverbs 16:18). Historico-strategically, a “surprise incursion” could explain how an over-confident king was struck down quickly within his own palace.

Conclusion

Despite some claims of a peaceful surrender, the historical and archaeological data do not rule out a targeted overthrow and killing of Belshazzar. Multiple ancient texts describe Cyrus’s victory as surprisingly rapid rather than entirely bloodless. The biblical record in Daniel 5:30 pinpoints Belshazzar’s death as happening “that very night,” which harmonizes with the notion of a sudden, surgically executed palace coup. God’s judgment upon Belshazzar, as foretold by Daniel, occurred in dramatic fashion, consistent with both the divine message of imminent consequence and the historical evidence that Babylon’s leadership fell in a rapid, decisive event.
