When you think of legendary warlords, names like Alexander or Genghis often dominate the conversation. Yet a deeper dive into history reveals a roster of 10 forgotten conquerors whose ambition, bloodshed, and brilliance altered the fate of continents. These leaders may have slipped out of mainstream memory, but their stories still echo through ruins, tablets, and epic poetry.
10 Forgotten Conquerors Overview
10 Lugalzagesi
Civilization sprouted in ancient Sumer, nestled between the Tigris and Euphrates. By 2330 BC, turmoil roiled the region and cities lay in ashes. The chaos bore the hallmark of Lugalzagesi, ruler of Umma. Before seizing the throne, he served as priest to the goddess Nisaba, and scholars have dubbed him an “ecstatic” and a “bone‑fidе berserk” to explain the unparalleled devastation he unleashed.
Shortly after becoming king of Umma, Lugalzagesi also claimed Uruk—likely through marriage. He then launched a feverish series of campaigns against Lagash, eventually overtaking the city itself. A Lagash priest recorded his ruthlessness: “he set fire to the [temples] … he plundered the palace of Tirash, he plundered the Abzubanda temple, he plundered the chapels of Enlil and Utu.”
Another inscription captures the bitterness of Lagash’s defeated monarch: “The leader of Umma, having sacked Lagash, has committed a sin against Ningirsu. The hand which he has raised against him will be cut off! May Nisaba, the god of Lugalzagesi, ruler of Umma, make him bear the sin.” Yet the sack of Lagash only amplified Lugalzagesi’s power. Soon he ruled all of Sumer, commanding primeval cities such as Ur, Zabala, and Nippur. His forces swept from the Persian Gulf to the Mediterranean: “Enlil, king of all lands, gave to Lugalzagesi the kingship of the nation, directed all eyes of the land toward him, put all the lands at his feet … from east to west, Enlil permitted him no rival.”
Enlil’s favor waned when Lugalzagesi’s expansion collided with a minor ruler named Sargon. In a stunning upset, Sargon’s disciplined troops crushed the relatively primitive Sumerian armies. Lugalzagesi was paraded in chains through Nippur, fading into obscurity while Sargon of Akkad forged the first great empire.
9 Modu Chanyu
The Eurasian Steppe—an endless sea of grass stretching from Mongolia to Eastern Europe—gave birth to the first domesticated horses. Periodically, nomadic horsemen united under a charismatic leader, shaking the civilized world. While Attila, Genghis, and Timur dominate popular memory, Modu Chanyu, an early Xiongnu ruler, remains almost invisible in Western narratives.
Modu’s father ruled the Xiongnu, a people inhabiting modern‑day Mongolia. The reigning king favored Modu’s brother, prompting Modu to murder his sibling and seize power. According to historian Sima Qian, Modu invited his bodyguards for archery practice, demanding they use his prized horse as a target. When some objected, he executed them on the spot. He then ordered them to aim at his wife; again, dissent was met with death. Finally, he declared his father the next target, and the guards shot him without hesitation.
After eliminating his rivals, Modu embarked on lightning‑fast campaigns against the Donghu and Yuezhi, building an empire that spanned the eastern steppes. In 200 BC he baited Chinese Emperor Gaozu into an ambush, forcing a humiliating treaty: China paid tribute and Gaozu pretended to send his daughter as a concubine, though he actually sent another girl and lied about her identity. In a grim twist, the Yuezhi king’s skull was fashioned into a drinking cup by Modu’s son. Modu died in 174 BC, leaving an empire rivaling that of Alexander the Great.
8 Cyaxares
For centuries, the Assyrian Empire dominated the ancient Middle East, its influence reaching the lands of the Medes in present‑day Iran. The Medes harbored mixed feelings toward Assyrian domination, and a nobleman named Phraortes led a revolt around 653 BC. The Assyrian bowmen, however, were fearsome, and the rebellion was crushed; Phraortes was executed, leaving his grieving son Cyaxares to inherit the quest.
Cyaxares faced a daunting task, especially since Scythians had invaded Media during the turmoil. He initially submitted to Scythian authority, biding his time until he could lure their leaders to a banquet. Once the Scythians were drunk, Cyaxares ordered their slaughter. He then unified the Medes into a single kingdom under his command, overhauling the army with new weapons and a focus on cavalry—an area where the Assyrians lagged.
In 614 BC the Medes attacked, sacking the Assyrian stronghold at Ashur. Over the next two years they pressed toward Nineveh, which finally fell in 612 BC. Cyaxares avenged his father and dismantled the greatest empire of his day. The Median Empire seemed poised to dominate the ancient world—had its successor not crossed paths with a young Persian leader named Cyrus, the course of history might have shifted dramatically.
7 Nabopolassar
Cyaxares did not fight alone against Assyria. To topple the mighty empire, the Medes forged an alliance with Nabopolassar, a rebel who crowned himself king of Babylon. Babylon, a jewel in Assyria’s crown, suffered repeated revolts—first in 705 BC, then again in 651 BC—both brutally suppressed by the Assyrian king Sennacherib, who laid waste to the city.
Nabopolassar emerged from an obscure Chaldean tribe, his monuments even labeling him the “son of a nobody.” Yet he rose as a famed resistance leader, conducting guerrilla warfare from the marshy delta of the Tigris and Euphrates. When Babylon’s citizens overthrew their governor in 630 BC, they invited the seasoned veteran to become their king.
For fifteen years Nabopolassar waged a desperate campaign to expel the Assyrians from Babylonia. By 616 BC he succeeded, launching attacks on Assyria itself. In 612 BC he sealed a treaty with Cyaxares, and together their forces razed Nineveh. Afterwards they divided the Assyrian remnants: Nabopolassar crushed a lingering Assyrian rump state in Syria and defeated an Egyptian intervention. He died in 605 BC, and his Neo‑Babylonian Empire later crumbled when Cyrus the Great’s Persians appeared on Babylon’s doorstep.
6 Piye
In the eighth century BC, Egypt fell into chaos. Minor kings squabbled, and the northern region fell under Libyan warlords who showed little reverence for Egyptian deities. The priests of Amun, seeking stability, turned their gaze southward to Nubia—the “Black Pharaohs” of Kush. This powerful African kingdom, heavily influenced by Egyptian culture (modern Sudan still boasts more pyramids than Egypt), became the custodian of Egyptian traditions.
Piye, a Kushite pharaoh, was an unusually reluctant conqueror. Though his influence stretched over southern Egypt, he might have been content to let the north remain autonomous. Yet Piye’s devotion to Amun compelled him to act. A famed monument records his fury: “I swear, as Re loves me, as my father Amun favors me, I shall go north myself … And I shall let Lower Egypt taste the taste of my fingers!”
True to his vow, Piye’s armies marched up the Nile, sanctifying themselves with holy water before each battle. The Libyan fleet burned on the Nile, while Nubian forces stormed Hermopolis and Memphis. The Delta ruler Tefnakht surrendered, writing to Piye: “I cannot stand before your flame, I dread your grandeur.” After achieving total victory, the pious Piye withdrew, returning to his Nubian homeland. His successor Shabaka later resumed the campaign in 719 BC, cementing the 25th Dynasty of Egypt.
5 Dhu Nawas
In the sixth century AD, the last Jewish king of Arabia watched a gruesome battle unfold along a Yemeni beach. Known as Yusuf Al‑As’ar, his flowing hair earned him the nickname Dhu Nawas—“Lord of the Sidelocks.” When his foes gained the upper hand, he spurred his heavily armored horse into the Red Sea, which lived up to its name by swallowing him in a tide of blood.
Before Islam’s rise, Yemen was a theater of conflict between Zoroastrian Persia and the Christian powers of Byzantium and Abyssinia (modern Ethiopia). An Abyssinian governor had previously ruled Yemen before Dhu Nawas seized power. His conversion to Judaism may have been a statement of independence from both Persian and Abyssinian influences. Regardless, chronicles agree he launched a ferocious campaign against Abyssinian Christians in Yemen, massacring them wherever he could.
By around AD 525, Dhu Nawas had secured control of Yemen. This inevitably provoked Abyssinia, and the Negus (king) Kaleb mounted a full‑scale invasion from Axum. Dhu Nawas met the African forces on the very beach they attempted to land, but the Abyssinians proved too powerful, forcing him into his legendary ride into the sea.
4 Brennus
After Alexander the Great’s death in 323 BC, his empire fractured, and his successors turned on each other. Roughly forty years later, the chaos allowed a massive force of Celtic tribesmen to sweep down from the north, pillaging the old Macedonian kingdom.
The Gauls were led by a chieftain named Brennus, who had united a sizable army from diverse tribes. After ravaging Macedon, Brennus (perhaps a title rather than a personal name) set his sights on the richer prize of Greece. The panicked Greeks hastily formed an alliance and chose to make a stand at the famed pass of Thermopylae—the same narrow gateway where the 300 Spartans once faced the Persians.
Yet Brennus proved cunning. He dispatched troops to raid the exposed Greek state of Aetolia, prompting the Aetolians to abandon Thermopylae to defend their own lands, thereby reducing the Greek defenders. He then bribed locals to reveal the same mountain path Xerxes had used to outflank the Spartans. Sensing the shifting wind, the Greeks opted not to make another last stand, instead escaping aboard the Athenian navy.
With Greece at his mercy, Brennus marched on the wealthy oracle at Delphi. However, internal disputes delayed the Gauls. Just as they prepared to assault Delphi, a sudden snowstorm descended. The Greeks, claiming divine intervention, launched a counter‑attack, driving the Celts back north. Legends persisted that a sacred pool in Gaul glimmered with the stolen Greek gold and jewels.
3 Pachacuti
In the 15th century, the Peruvian Chanca people aggressively expanded their domain. Armed with a large, seasoned army and talented generals, few dared oppose them. Around 1438 they set their sights on Cuzco, the capital of the relatively obscure Inca civilization. Inca ruler Viracocha and his heir Urcon wisely abandoned the capital, but Viracocha’s son Cusi Yupanqui refused to flee.
Gathering a handful of loyalists, Cusi Yupanqui somehow managed to defeat the Chanca in a battle where even stones rose from the battlefield to aid him—a boast likely reflecting his strategic use of rockslides, a later Inca hallmark. After emerging victorious, he adopted the name Pachacuti, meaning “Earthshaker.” He deposed his cowardly father and eliminated his brother, setting his sights on empire‑building.
First, Pachacuti targeted the cities surrounding Cuzco, claiming they had failed to aid the Inca during the Chanca onslaught. Consolidating a solid base, he expanded outward, conquering vast ancient provinces such as Vilcas, Soras, Aymaraes, and Omayasos. When his general Capac Yupanki seized the north, Pachacuti welcomed him back—only to execute him immediately, preventing any future threat.
By the time he reached old age, the Inca dominated Peru. Satisfied, the Earthshaker passed the army to his son, retired, and spent his later years tinkering with Cuzco’s architecture.
2 Zenobia
Few women ruled autonomously in antiquity, but those who did often outmatched their male counterparts. Zenobia, queen of Palmyra, epitomized this spirit—marching on foot alongside her troops and often outdrinking them. In the third century AD she assembled a short‑lived empire stretching from Egypt to Turkey, posing a genuine threat to Rome.
Her ascent began when she married Lucius Odaenthus, the Roman governor of Syria. The pair formed a formidable duo, though Zenobia famously refused to sleep with her husband except to conceive their sole son. In 266 BC (likely a typo in source; intended 266 AD), Lucius was mysteriously assassinated along with his son from a previous marriage. Instead of awaiting a Roman appointment, Zenobia installed her young son as governor and declared herself regent.
At the time, Rome was plagued by a rapid succession of short‑lived emperors, too preoccupied with internal murders to challenge Zenobia. She then turned her gaze to Egypt. Rather than openly breaking from Rome, she dispatched an agent to spark a rebellion there. Her armies swooped in, crushing the “rebellion” and returning Egypt to Roman rule—albeit under Palmyrene control.
When an actual Roman army arrived in Egypt, Zenobia revealed her true colors, slaughtering the invaders. The winds shifted, and the Roman East eventually rallied behind Emperor Aurelian, a seasoned soldier. After a hard‑fought campaign—during which Zenobia escaped three sieges, once even riding a camel while cradling her son—she was captured and taken to Rome, where she lived out her remaining years in quiet obscurity.
1 Lord 8 Deer Jaguar Claw
In the 11th century, the Mixtec comprised a patchwork of principalities along Mexico’s Pacific coast. They chronicled history in codices that blended pictures and text, resembling modern comic books. These codices recount the saga of 8 Deer Jaguar Claw, a conqueror who rose to towering heights before meeting a tragic demise.
Born into Tilantongo’s royal family, 8 Deer was not initially in line for the throne. At eighteen, he sought an audience with the oracle Lady 9 Grass—a terrifying figure seemingly lacking flesh on her lower jaw. The codices are ambiguous: either 9 Grass advised 8 Deer to journey to the shore, or she exiled him there. Either way, 8 Deer and his followers left Tilantongo, founding the coastal town of Tututepec.
Here, 8 Deer’s brilliance shone. He forged an alliance with Toltec merchants eager for coastal commodities like salt and cacao. With the profits, he launched a conquest campaign, starting with modest villages along the coast and progressing to larger inland cities. As his wealth and influence grew, members of Tilantongo’s royal family began to die, bringing him closer to the throne. A final brother’s mysterious stabbing crowned him king.
Next, 8 Deer turned his wrath toward Tilantongo’s ancient foe, the city known as Red‑And‑White Bundle. This conflict was personal; he secretly loved 9 Monkey, wife of Red‑And‑White Bundle’s king. Tragically, when 8 Deer stormed the enemy palace, he found 9 Monkey and her husband already dying. In an uncharacteristic moment of weakness, he spared 9 Monkey’s son. This mercy proved fatal: the boy escaped, sought aid from the Zapotec Empire—concerned about 8 Deer uniting the Mixtec—and returned with an army that defeated the aging ruler. The conqueror was personally executed by the very boy he had spared out of love.
