In 88 BCE, as the Social War waned, Rome assigned Sulla to fight Mithridates. A political counter‑move, helped by an enlarged electorate, reassigned the command—prompting Sulla to march his legions on Rome. Appian ties the crisis to the war’s end.
What Happened
Peace at home proved fragile. In 88 BCE, while Asculum’s rubble settled and Samnite resistance flickered, the Senate appointed Sulla to the war against Mithridates of Pontus. The choice reflected his Social War wins at Nola and across Samnium, and the legions’ loyalty he had gathered. Then politics intervened. Through maneuvers in assemblies swollen with new citizens, the command was reassigned—back toward Gaius Marius’s orbit [14].
Appian tells it as a chain: the Social War’s close, the new voters’ weight, and the distribution of commands combined to spark an internal explosion [1][14]. In Rome, the Forum’s stone rang with shouting; tribunes proclaimed; rumors flew up the slopes of the Palatine and down the Vicus Tuscus. The colors were civic, not martial—purple‑bordered togas and tablets—but the sound was a drumbeat.
Sulla made his choice outside the city, in Campania, among men who had fought under him at Nola and Beneventum. He would not surrender the command. Standards were raised; eagles tilted toward Rome. The legions’ boots thudded on the Via Appia as they marched north, a sight and sound no Roman had expected to see—Roman soldiers advancing on their own capital.
Appian links this moment directly to the Social War’s legacy: newly enfranchised citizens behaved as citizens, shifting votes and power calculations. Command, electorates, and personal armies had been forged together in the crucible of 90–88 BCE. When they collided, they produced civil war [14].
In the city, panic. Gates closed; meetings dissolved; senators fled to villas near Tibur and Praeneste. The Capitol’s bronze glinted under an anxious sun. Sulla entered Rome with columns tight, horns quiet, an aggression that was precise and practiced. The Social War had ended; the Marian–Sullan war began.
From Capua to the Campus Martius to the bustling port at Ostia, people understood the transition. The instruments of integration—citizenship expansion, tribal enrollments—had remade the electorate. Combined with a general who believed his claim and his soldiers’ devotion trumped votes, they turned a legal dispute into a march. War had come home.
Why This Matters
Sulla’s march tied the Social War’s outcomes to civil conflict. The enlarged citizen body, enrolled through the lex Iulia and lex Plautia Papiria, altered political dynamics enough to make command assignments unstable. Appian’s narrative emphasizes that the end of fighting against allies opened a door to fighting among Romans [14].
The event embodies the theme “from integration to civil war.” The same mechanisms that solved one legitimacy crisis—enfranchising Italians—created a new one when rival elites competed to wield the state’s now‑vast capacity. Sulla’s personal authority, forged in southern campaigns, supplied the muscle behind the political move.
This moment resets the story’s stakes. After 88 BCE, Italy south of the Po is largely inside the citizen body; the question shifts from whether Italians are Roman to which Romans decide for all. The Social War’s end is thus not an endpoint but a pivot to the Republic’s last, bloodiest acts.

People Involved
Key figures who played a role in Sulla’s Eastern Command Triggers March on Rome
Gaius Marius
Gaius Marius, the novus homo from Arpinum who smashed the Cimbri and Teutones, brought his seasoned eye to the Social War in 90 BCE. Serving after the death of the consul P. Rutilius Lupus, he steadied shaken troops and won solid though unspectacular victories against experienced Italian foes. For a moment his rivalry with Sulla cooled as both fought for Rome. Marius belongs in this timeline as the old warhorse whose presence helped hold the line—and whose later struggle with Sulla, reignited by the Mithridatic command, turned the war’s end into civil strife.
Lucius Cornelius Sulla
Lucius Cornelius Sulla rose from a poor patrician branch to become Rome’s most ruthless political soldier. In the Social War he delivered a string of victories in Campania and Samnium—wins at Nola and beyond that earned him rare honors and set his reputation as a field commander. His success, and the senate’s choice to grant him the Mithridatic command in 88 BCE, detonated the rivalry with Marius and led to his unprecedented March on Rome. Sulla belongs in this timeline as the general who helped end the war in the south and whose ascent turned its aftermath into civil conflict.
