I keep hearing about Caligula and degeneracy. What did he do exactly?
Caligula - Wikipedia
Seneca the Younger, contemporaries of Caligula, describe him as an insane emperor who was self-absorbed, short-tempered, killed on a whim, and indulged in too much spending and sex.
[102] He is accused of sleeping with other men's wives and bragging about it,
[103] killing for mere amusement,
[104] deliberately wasting money on his bridge, causing starvation,
[54] and wanting a statue of himself in the
Temple of Jerusalem for his worship.
[98] Once, at some games at which he was presiding, he was said to have ordered his guards to throw an entire section of the audience into the arena during the intermission to be eaten by the wild beasts because there were no prisoners to be used and he was bored.
[105]
While repeating the earlier stories, the later sources of Suetonius and Cassius Dio provide additional tales of insanity. They accuse Caligula of
incest with his sisters, Agrippina the Younger, Drusilla, and Livilla, and say he prostituted them to other men.
[106] They state he sent troops on illogical military exercises,
[74][107] turned the palace into a brothel,
[47] and, most famously, planned or promised to make his horse,
Incitatus, a consul,
[108][109]and actually appointed him a priest.
[83]
he’s generally synonymous with all manner of debauchery from an emperor in Imperial Rome.
