Lucius Marcius Philippus (born before 102 BC) was a politician and senator in the late Roman republic. He was governor of Syria from 61 to 60 and later served in the consulship of 56 BC. He was also step-father of the emperor Augustus. Biography and was the son of the consul in 91 BC and censor in 86 BC of the same name. He also had a brother, Quintus, who served as proconsul in Cilicia from 47 to 46 BC. His first known office was that of praetor in the year 62 BC. After the organisation of Roman Syria, carved out as a province from the Selucid Empire by Pompey in 64 BC, it was governed by two propraetorian governors. Philippus was one of them. He succeeded Marcus Aemilius Scaurus, who had governed the province as Pompey's proquaestor pro praetore; Phillipus served there two years, from 61 through 60 BC. Consulship In 56 BC, he entered office as consul with Gnaeus Cornelius Lentulus Marcellinus as his colleague. Before the two entered office, they supported putting Publius Clodius Pulcher on trial before elections for aedile; they had secured a senatorial decree to that effect, but after strenuous objections from Clodius' allies in the senate – including Quintus Caecilius Metellus Nepos (then-consul) and Gaius Porcius Cato (a tribune) – it was overruled amid demonstrations by Clodius' supporters. That year, Marcellinus engaged in vehement attacks on Caesar and Pompey, which Philippus supported. The consuls together opposed extension of Caesar's Gallic command and the aims of the so-called First Triumvirate and its members. When Crassus and Pompey decided to stand for the consulship of 55 BC, Philippus and Marcellinus opposed them; "only by desperate postponement of the elections into the following year", coupled with strong-arm intimidation tactics and Caesar's sending of his men on leave to vote in Rome, were Crassus and Pompey able to overcome the considerable opposition to them and win election as consuls in late January 55 BC. The next year, 54 BC, Philippus joined Clodius, Cicero, Milo, Pompey, and a number of other senior statesmen (including nine former consuls) in defending Marcus Aemilius Scaurus on charges of repetundae. Scaurus, calling on connections across the aristocracy – "no other trial in the republic evoked the participation of so many distinguished and diverse individuals" – was overwhelmingly acquitted. Some time after 59 BC and probably also after his consulship in 56 BC,
