Rome’s most infamous political insult may have involved a horse.

According to ancient writers, Emperor Caligula planned to make his favorite racehorse, Incitatus, a consul... one of the highest offices in the Roman world.

Not a mascot.

Not a joke title.

A consul.

The story became legendary because it perfectly captured how Romans viewed Caligula’s reign: humiliating, unpredictable, and openly contemptuous of the Senate.

Incitatus supposedly lived better than most nobles. He had:

• A marble stable

• An ivory manger

• Purple blankets reserved for royalty

• Jewelled collars

• His own servants

Ancient historians claimed Caligula even invited guests to dine in the horse’s honor.

But modern historians suspect something even more interesting:

The horse may have been a political joke.

By Caligula’s time, Rome still pretended the old Republic existed. Senators still competed desperately for ancient offices like the consulship, even though everyone knew the emperor held the real power.

And Caligula seems to have enjoyed exposing that reality.

By threatening to appoint a horse consul, he was essentially telling Rome’s elite:

“Your highest office means so little… even my horse could do it.”

That insult may have mattered more than the horse itself.

In AD 41, after years of public humiliation and fear, Caligula was assassinated by members of his own Praetorian Guard. He was stabbed more than 30 times beneath the Palatine Palace.

Afterward, Roman writers painted him as a mad tyrant.

And the horse story survived for nearly 2,000 years.

Not necessarily because it was true…

But because Romans believed Caligula was exactly the kind of emperor who might actually do it.
