Gaius Antonius Hybrida

Gaius Antonius Hybrida (flourished 1st century BC) was a politician of the Roman Republic. He was the second son of Marcus Antonius and brother of Marcus Antonius Creticus; his mother is unknown. He was also the uncle of the famed triumvir Mark Antony. He had two children, Antonia Hybrida Major and Antonia Hybrida Minor.

Hybrida's career began under Lucius Cornelius Sulla, whom he accompanied into Greece as either a military tribune or a legatus. Later, in 63 BC, he was elected to serve as consul of the Roman Republic alongside Marcus Tullius Cicero. The two struck a deal which effectively allowed Cicero to rule as sole consul in exchange for Hybrida receiving the governorship of Macedonia at the end of his term. The same year, Hybrida was involved in the Catilinarian Conspiracy, a plot against the Roman Senate led by Lucius Sergius Catilina, or "Catiline", and which culminated in a battle at Pistoria and the death of Catiline. Having served his term as consul, Hybrida was granted Macedonia as had been promised. Here, Hybrida abused his rule to rob the provincials and led invasions of the neighbouring barbaric lands of Moesia. His incursions brought two separate attacks from the natives who successfully forced Hybrida out of their lands without any loot.

In 60 BC, Hybrida was quietly removed from the position of governor of Macedonia and replaced by Gaius Octavius. The next year, he was prosecuted by Julius Caesar and Marcus Licinius Crassus. The outcome of this was that Hybrida was forced to pay a fine and banished to the Island of Cephallenia. Sometime in 47, Hybrida was recalled from his banishment by Caesar. In 45, he made himself a candidate for the position of censor which ultimately failed. The final mention of Hybrida comes from Cicero in 44 when Mark Antony divorced himself from Hybrida's daughter Antonia Hybrida Minor.
