The Roman Senate was a political institution in ancient Rome. It was one of the most enduring institutions in Roman history, being founded in the first days of the city (traditionally founded in 753 BC). It survived the overthrow of the kings in 509 BC, the fall of the Roman Republic in the 1st century BC, the split of the Roman Empire in 395 AD, and the fall of the Western Roman Empire in 476 AD.

During the days of the kingdom, it was little more than an advisory council to the king. The last king of Rome, the tyrant Lucius Tarquinius Superbus, was overthrown following a coup d'état led by Lucius Junius Brutus.

During the early Republic, the Senate was politically weak, while the executive magistrates were quite powerful. Since the transition from monarchy to constitutional rule was probably gradual, it took several generations before the Senate was able to assert itself over the executive magistrates. By the middle Republic, the Senate reached the apex of its republican power. The late Republic saw a rise in the Senate's power, which began following the reforms of the tribunes Tiberius and Gaius Gracchus.

Mark Antony (Latin: M·ANTONIVS·M·F·M·N) (January 14, 83 BC – August 1, 30 BC) was a Roman politician and general. As a military commander and administrator, he was an important supporter and loyal friend of his mother's cousin Julius Caesar. After Caesar's assassination, Antony formed an official political alliance with Octavian (the future Augustus) and Lepidus, known to historians today as the Second Triumvirate.

The triumvirate broke up in 33 BC. Disagreement between Octavian and Antony erupted into civil war, the final war of the Roman Republic, in 31 BC. Antony was defeated by Octavian at the naval Battle of Actium, and in a brief land battle at Alexandria. He and his lover Cleopatra committed suicide shortly thereafter. His career and defeat are significant in Rome's transformation from Republic to Empire.

A member of the Antonia clan (gens), Antony was born on January 14, 83 BC. He was the homonymous and thus presumably the eldest son of Marcus Antonius Creticus (praetor 74 BC, proconsul 73–71 BC) and grandson of the noted orator Marcus Antonius (consul 99 BC, censor 97–6 BC) who had been murdered during the Marian Terror of the winter of 87–6 BC.
