Marcus Octavius (tribune of the plebs 133 BC)
Marcus Octavius (Latin: M·OCTAVIVS·CN·F·CN·N, lived during the 2nd century BC) was a Roman tribune in 133 BC and a major rival of Tiberius Gracchus. He was a son of Gnaeus Octavius, the consul in 165 BC, and a brother to another Gnaeus Octavius, the consul in 128 BC. Through his brother, he was the paternal uncle of Gnaeus Octavius, the consul in 87 BC. A serious and discreet person, he earned himself a reputation as an influential orator. Though they had originally been close friends, Octavius became alarmed by Gracchus's populist agenda and, at the behest of the Roman senate, repeatedly vetoed Gracchus's programmes of land reform.
