In 36 BCE, with Sextus gone, Lepidus tried to use his Sicilian legions to challenge Octavian—and lost [4][16]. On Sicily’s beaches, standards dipped as troops defected. Three rulers became two; Lepidus kept only his priesthood.
What Happened
The smoke of burning triremes had barely lifted over Naulochus when Marcus Aemilius Lepidus made his move. He had ferried legions from Africa to Sicily for the final campaign against Sextus Pompeius; now, with the island secured, he argued that command of Sicily—and perhaps more—was his by right. The island’s beaches near Lilybaeum and Agrigentum saw a different kind of surf: shifting loyalties [4][16].
Octavian moved fast. He crossed from Italy to confront Lepidus in person, bringing with him the aura of fresh victory and the promise of pay. The scene on the Sicilian sands played out as theater and referendum. When the two leaders addressed the troops, the wind snapped at the scarlet vexilla; the only sound between speeches was the hiss of the sea. Then standards tilted—toward Octavian [4].
Lepidus’ legions transferred allegiance in a cascade. Leadership in the late Republic was measured in soldiers as much as in votes, and Sicily’s cohorts were counting. The man who had been one of the three legal architects of Rome’s emergency state now found himself isolated in his own camp, his proclamations drowned by the murmur of desertion [4][16].
Octavian spared his life but not his power. Lepidus was stripped of his provincial commands and sent into political eclipse, retaining only the lifetime priesthood of pontifex maximus. The office’s purple-bordered vestments could not conceal the gray reality: the Triumvirate was now a duumvirate in practice [4][16].
Rome learned the news down the Appian Way. Senators climbing the Capitoline understood its arithmetic: with Lepidus sidelined, the Mediterranean had two poles—Antony in the East, Octavian in the West. The Senate’s sentences, the people’s shouts, and the legions’ loyalty would pivot within that simplified geometry.
Sicily’s quiet in the aftermath was the quiet of reorganization. Garrisons were reassigned at Messana and Syracuse; grain ships queued again at Lilybaeum. The oars’ creak on the Tyrrhenian sounded like a metronome regulating Octavian’s next decision: confrontation with Antony [4][16].
Why This Matters
Removing Lepidus collapsed the legal fiction of three-man rule into the reality of a bipolar contest. Octavian gained troops, territory, and the appearance of clemency—all assets in the coming ideological fight with Antony [4][16].
It fits the theme of alliances to eliminate rivals. The very structure that had united three men to destroy Caesar’s killers now enabled one to neutralize another without a pitched battle, using presence, pay, and prestige. Sicily became a stage on which legality and loyalty traded places [4].
In the larger story, Lepidus’ fall simplified choices for cities and client kings. They could calibrate between two centers instead of three. That clarity sharpened later propaganda: Antony’s association with Cleopatra could be painted as eastern excess; Octavian’s as Italian virtue. Sicily’s sands pointed to Actium’s seas [16].
Modern readers see in Lepidus’ demotion the precariousness of Roman eminence. Offices like pontifex maximus could gild irrelevance; only legions conferred reality. Augustus later ensured that such misalignments became impossible by embedding military command within his person [4][16].

People Involved
Key figures who played a role in Lepidus Removed from Power
Marcus Vipsanius Agrippa
Marcus Vipsanius Agrippa (63–12 BCE) was Octavian’s closest friend, field commander, and problem-solver—the engineer of victory as Rome turned from republic to empire. He built and commanded the fleets that crushed Sextus Pompey at Naulochus (36 BCE) and Mark Antony at Actium (31 BCE), then remade Rome with aqueducts, baths, and the first Pantheon. Loyal, practical, and unglamorous, Agrippa made Augustus’s political magic possible by delivering military certainty and civic prosperity. In this timeline, he is the quiet architect behind the decisive battles and the marble peace that followed.
Marcus Aemilius Lepidus
Marcus Aemilius Lepidus (c. 89–13 BCE) was the least formidable—but necessary—third of the Second Triumvirate. A loyalist of Julius Caesar and later pontifex maximus, he helped broker the pact with Antony and Octavian in 43 BCE, contributed forces against Sextus Pompey, and then overreached. In 36 BCE, Octavian stripped him of power and confined him to a priesthood. Lepidus’s rise and fall reveal how Octavian eliminated rivals without shattering the veneer of legality.
