Which Roman general was married to Julius Caesar's aunt Julia?

Which Roman general was married to Julius Caesar’s aunt Julia? The answer is Gaius Marius.

Gaius Marius, one of the Roman Republic’s most important generals and politicians, married Julia around 110 BC. Julia was the paternal aunt of Julius Caesar, making Marius Caesar’s uncle by marriage. Their son, Gaius Marius the Younger, later became a political and military figure in his own right.

The marriage also connected an ambitious “new man” from outside Rome’s old patrician elite with the distinguished Julii Caesares family. Plutarch says that marrying the patrician Julia helped Marius gain attention in the Roman Senate and advance his political career. Marius went on to hold the consulship seven times and became famous for victories in the Jugurthine and Cimbrian wars.

This relationship is easy to confuse with Caesar’s later alliance with Pompey the Great. Caesar’s daughter Julia married Pompey in 59 BC, creating a separate and famous family-political connection. Marius was not Caesar’s father-in-law; he was married to Caesar’s aunt. Julia died in 69 BC, and Caesar delivered a notable funeral eulogy for her.
