When-was-Amos-written
Short answer: Amos 1:1 gives the date in the same breath as the prophet's name: the words of Amos were seen concerning Israel in the days of Uzziah king of Judah and Jeroboam the son of Joash king of Israel, two years before the earthquake. Those two reigns overlap only in the first half of the eighth century BC, and Jeroboam II died around 753 BC, so Amos preached roughly between 767 and 753 BC. Most conservative and critical scholars alike settle near 760 BC. The earthquake mentioned in Amos 1:1 is remembered centuries later in Zechariah 14:5, which shows it was a real, datable event in Judah's memory. Nothing in the book requires a later date, and the political situation it describes fits the long peace of Jeroboam II's reign.
The date marker embedded in Amos 1:1
Most prophetic books begin with a superscription giving historical coordinates, and Amos is no exception. Amos 1:1 reads, in part, that the words were seen concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam the son of Joash king of Israel, two years before the earthquake. That single sentence gives us three anchors: a Judean king, an Israelite king, and a natural disaster memorable enough to serve as a calendar date.
The phrase in the days of does not mean during the whole reign of either king. It means the two reigns overlapped during the period when Amos spoke. Uzziah, also called Azariah, ruled Judah for fifty-two years, and Jeroboam II ruled Israel for forty-one years from Samaria, according to 2 Kings 14:23. Their reigns ran side by side for a stretch of roughly twenty-seven years, and within that window Amos ministered.
The earthquake narrows things further. If Amos spoke two years before it, then the quake is the fixed point, and the prophecy comes just before it. Zechariah 14:5 later refers to the earthquake in the days of Uzziah king of Judah as a byword for terror and flight, which confirms that the event was known to later generations. Archaeology has also uncovered a destruction layer at Hazor from the mid-eighth century BC that many scholars associate with this same earthquake, though that identification is a reasonable inference rather than a statement the text itself makes.
What Uzziah and Jeroboam II's reigns tell us
Jeroboam II came to the throne in the fifteenth year of Amaziah king of Judah, according to 2 Kings 14:23, and he reigned forty-one years in Samaria. That places his reign from roughly 793 to 753 BC. Uzziah began to reign in Judah around 792 BC and reigned until about 740 BC. The overlap of their reigns spans approximately 793 to 753 BC, so Amos must have preached somewhere inside that period.
Because Amos spoke two years before the earthquake, and because the earthquake is generally placed in the 760s BC, the prophecy lands in the later part of Jeroboam's reign, not the beginning. A date near 760 BC is widely held, and some place it a few years earlier or later depending on how the earthquake is dated. The text does not demand precision to the exact year, and honest readers should not pretend it does.
What the reigns do tell us is the atmosphere. Jeroboam II recovered Israelite territory and brought a season of military and economic strength. Uzziah strengthened Judah's defenses and agriculture. Amos spoke into that prosperity, not into collapse. This matters, because the book's accusations of injustice and empty religion make most sense against a backdrop of comfortable affluence.
Two years before the earthquake: a real event, not a riddle
The earthquake is not a literary device. Amos 1:1 treats it as a known event, and Zechariah 14:5 refers back to it as something people fled from in living memory: you shall flee, just like you fled from before the earthquake in the days of Uzziah king of Judah. That later reference, written centuries afterward, shows the quake remained a landmark in Israel's memory.
Amos also alludes to seismic imagery throughout his oracles, and the book's opening vision has Yahweh roaring from Zion. Whether the prophet's preaching anticipated the quake or simply preceded it, the superscription functions as a timestamp. Readers in ancient Israel would have known exactly when this was. It is a little like dating a letter to the year of a famous flood or fire.
Some interpreters have tried to use the earthquake to fix the date precisely, but the exact year of the quake is not recorded in Scripture. Geological and archaeological estimates cluster in the mid-eighth century BC, often around 760 BC. The safest statement is that Amos preached in the years just before that event, in the 760s BC.
The political situation Amos addresses
Amos condemns nations around Israel before turning to Israel itself, and the list assumes relative security and prosperity. Damascus, Gaza, Tyre, Edom, Ammon, and Moab are all judged, then Judah, then Israel. This order reflects an era when Israelite borders were secure and trade routes were open, which fits the reign of Jeroboam II rather than the chaotic decades that followed.
Socially, the book attacks those who store up violence and robbery in their palaces and who sell the righteous for silver. Economic strength had produced a comfortable upper class and a vulnerable poor. That situation does not fit the period after 745 BC, when Tiglath-Pileser III of Assyria began pressing westward and Israel's independence rapidly eroded.
By the time Assyria annexed the northern kingdom and Samaria fell in 722 BC, the conditions Amos describes were gone. This is one reason a late date for Amos is difficult to maintain. The book breathes the air of the early-to-mid eighth century, before the Assyrian crisis dominated Israelite life.
Amos 7 and the confrontation with Amaziah
Amos 7:10-17 records the prophet's clash with Amaziah, the priest of Bethel, who sent word to Jeroboam king of Israel that Amos had conspired against him in the middle of the house of Israel. Amaziah then told Amos to flee to Judah and earn his bread there. This scene confirms that Amos prophesied in the northern kingdom during Jeroboam's reign, and it shows the royal sanctuary at Bethel as the center of opposition.
The passage also reveals how the establishment viewed Amos: as a threat to the state religion and to the king. That reaction fits a time when Bethel was a royal sanctuary supported by the crown, which is exactly what we would expect under Jeroboam II. A later setting under Assyrian pressure would not produce the same confident, prosperous temple establishment.
Amos replies that he was not a prophet by profession but a herdsman and a dresser of sycamore trees, and that Yahweh took him from following the flock. This personal detail is consistent with the superscription's description of him as one among the herdsmen of Tekoa, a town in Judah south of Bethlehem.
Objections to the early date and how they are answered
Some scholars have argued for a later date, sometimes after the fall of Samaria in 722 BC, because certain oracles seem to presuppose exile or destruction. Amos 5:1-6 opens with a lamentation over the house of Israel, and laments can sound like they describe something already happened. But prophetic laments frequently announce coming judgment, not past disaster. The lament form is a warning, not a retrospective.
Others point to references to Edom or to the house of David as evidence of a later setting. But Edom was a longstanding neighbor and rival throughout the monarchy, and the Davidic dynasty was a fact from the tenth century onward. Neither requires a post-exilic date. The linguistic features of Amos are early standard Hebrew, consistent with the eighth century.
The strongest reason for the early date remains the superscription itself. It names two kings and a known earthquake, and no later editor would have invented such specific, checkable coordinates. Faithful Christians may differ on the precise year, but the evidence points consistently to the middle of the eighth century BC, near 760 BC.
Why the date matters for reading Amos
Knowing when Amos preached shapes how we hear him. He was not a voice from a ruined nation looking back. He was a voice of warning to a confident, prosperous people who assumed God was pleased with them because their borders were secure and their temples busy. That is a message that lands differently when we realize it was spoken in peacetime, not in the aftermath of defeat.
The date also connects Amos to his near-contemporary Hosea, who ministered in the same northern kingdom, and to Isaiah and Micah in Judah. Together they form a chorus of eighth-century warning before Assyria became the instrument of judgment. Reading Amos alongside them helps us see how God patiently sent prophets before disaster, not only after it.
Finally, the date reminds us that Scripture is anchored in real history. Amos is not a timeless collection of moral sayings but the words of a specific man, in a specific place, at a datable moment. That is part of what makes the book trustworthy.
Biblical fidelity check
What Amos 1:1 establishes is limited and clear: the prophecy is dated to the reigns of Uzziah and Jeroboam II and to two years before a specific earthquake. It does not give a year number, a month, or a day, and it does not tell us how long Amos ministered. It also does not say the earthquake happened during a particular month or that the prophecy was written down immediately. Those are reasonable inferences at best.
A common misreading is to treat the phrase two years before the earthquake as a riddle or a symbol rather than a real event. But Zechariah 14:5 refers to the earthquake in the days of Uzziah king of Judah as something people fled from, which shows it was remembered as history. Another misreading assumes the superscription was added by a much later editor and is therefore unreliable. Nothing in the text requires that, and the specific, checkable details argue against it. The honest conclusion is that Amos preached around 760 BC, with some uncertainty about the exact year.
Other passages that speak to Amos 1:1
The dating of Amos is illuminated by several related passages. Second Kings 14:23-29 gives the regnal framework for Jeroboam II, which overlaps with Uzziah's long reign in Judah. Amos 7:10-17 narrates the confrontation with Amaziah at Bethel and confirms the prophet's northern ministry under Jeroboam. Zechariah 14:5 looks back on the earthquake in the days of Uzziah as a remembered event, anchoring the superscription in real history. Amos 5:1-6 shows the lament form that some read as evidence of a later setting. For related studies, see Why trust the Bible when it was written by humans?

Frequently asked questions
What year was Amos written?
Amos is usually dated to around 760 BC, based on the overlapping reigns of Uzziah of Judah and Jeroboam II of Israel, and on the reference to an earthquake two years after the prophecy. Jeroboam II reigned roughly 793 to 753 BC, and Uzziah roughly 792 to 740 BC. The earthquake is generally placed in the mid-eighth century BC. Some scholars allow a range from about 767 to 753 BC. The text does not give an exact year, so precision beyond that range is not warranted.
How does the earthquake in Amos 1:1 help date the book?
Because Amos 1:1 dates the prophecy two years before the earthquake, the quake becomes a fixed reference point. Zechariah 14:5 refers back to the earthquake in the days of Uzziah king of Judah as a known event, which confirms it was a real disaster in Judah's memory. Archaeological evidence at sites such as Hazor has been associated with a mid-eighth-century earthquake, though that link is an inference. Even without archaeology, the biblical references alone place Amos in the 760s BC.
Was Amos written before or after the fall of Samaria?
Amos was written well before the fall of Samaria in 722 BC. The book addresses a prosperous, secure northern kingdom under Jeroboam II, with a functioning royal sanctuary at Bethel and open trade routes. Those conditions fit the early-to-mid eighth century, not the period of Assyrian conquest. Amos warns that judgment is coming; he does not describe it as already arrived. That forward-looking stance is one of the strongest reasons to date the book before 722 BC rather than after it.
