Key events

1. Gallic War57 BCE
   The Gallic Wars were waged between 58 and 50 BC by the Roman general Julius Caesar against the peoples of Gaul. Gallic, Germanic, and Brittonic tribes fought to defend their homelands against an aggressive Roman campaign. The wars culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul. Though the collective Gallic armies were as strong as the Roman forces, internal divisions among the Gallic tribes eased victory for Caesar. Gallic chieftain Vercingetorix's attempt to unite the Gauls under a single banner came too late. Caesar portrayed the invasion as being a preemptive and defensive action, but historians agree that he fought the wars primarily to boost his political career and to pay off his debts. Still, Gaul was of significant military importance to the Romans. Native tribes in the region, both Gallic and Germanic, had repeatedly attacked Roman territory. Conquering Gaul allowed Rome to secure the natural border of the Rhine river.
2. Battle of Carrhae52 BCE
   The Battle of Carrhae was fought in 53 BC between the Roman Republic and the Parthian Empire near the ancient town of Carrhae. An invading force of seven legions of Roman heavy infantry under Marcus Licinius Crassus was lured into the desert and decisively defeated by a mixed cavalry of armored cataphracts and light horse archers led by the Parthian general Surena. On such flat terrain, the legion proved to have no viable tactics against the highly mobile Parthian horsemen, and the slow and vulnerable Roman formations were surrounded, exhausted by constant attacks, and eventually crushed. Crassus was killed along with most of his army. It is commonly seen as one of the earliest and most important battles between the Roman and Parthian Empires and one of the most crushing defeats in Roman history. According to the poet Ovid in Book 6 of his poem Fasti, the battle occurred on 9 June.
3. Battle of Alesia51 BCE
   The Battle of Alesia or Siege of Alesia was the climactic military engagement of the Gallic Wars, fought around the Gallic oppidum of Alesia in modern France, a major centre of the Mandubii tribe. It was fought by the Roman army of Julius Caesar against a confederation of Gallic tribes united under the leadership of Vercingetorix of the Arverni. It was the last major engagement between Gauls and Romans, and is considered one of Caesar's greatest military achievements and a classic example of siege warfare and investment; the Roman army built dual lines of fortifications—an inner wall to keep the besieged Gauls in, and an outer wall to keep the Gallic relief force out. The Battle of Alesia marked the end of Gallic independence in the modern day territory of France and Belgium.
4. Battle of Pharsalus47 BCE
   The Battle of Pharsalus was the decisive battle of Caesar's Civil War fought on 9 August 48 BC near Pharsalus in Central Greece. Julius Caesar and his allies formed up opposite the army of the Roman Republic under the command of Pompey. Pompey had the backing of a majority of Roman senators and his army significantly outnumbered the veteran Caesarian legions.
5. Battle of Thapsus45 BCE
   The Battle of Thapsus was a military engagement that took place on April 6, 46 BC near Thapsus. The forces of the Optimates, led by Quintus Caecilius Metellus Scipio, were defeated by the forces of Julius Caesar. It was followed shortly by the suicides of Scipio and his ally, Marcus Porcius Cato Uticensis, the Numidian king Juba, and his Roman peer Marcus Petreius.
6. assassination of Julius Caesar43 BCE
   Julius Caesar, the Roman dictator, was assassinated on the Ides of March, 44 BC, by a group of senators during a Senate session at the Curia of Pompey, located within the Theatre of Pompey in Rome. The conspirators, numbering 60 individuals and led by Marcus Junius Brutus, Gaius Cassius Longinus, and Decimus Junius Brutus Albinus, stabbed Caesar approximately 23 times. They justified the act as a preemptive defense of the Roman Republic, asserting that Caesar's accumulation of lifelong political authority—including his perpetual dictatorship and other honors—threatened republican traditions. The assassination failed to achieve its immediate objective of restoring the Republic's institutions. Instead, it precipitated Caesar's posthumous deification, triggered the Liberators' civil war between his supporters and the conspirators, and contributed to the collapse of the Republic. These events ultimately culminated in the rise of the Roman Empire under Augustus, marking the beginning of the Principate era.
7. Battle of Philippi41 BCE
   The Battle of Philippi was the final battle in the Liberators' civil war between the forces of Mark Antony and Octavian and the leaders of Julius Caesar's assassination, Brutus and Cassius, in 42 BC, at Philippi in Macedonia. The Second Triumvirate declared the civil war ostensibly to avenge Julius Caesar's assassination in 44 BC, but the underlying cause was a long-brewing conflict between the Optimates and the Populares.
8. Battle of Actium30 BCE
   The Battle of Actium was a naval battle fought between Octavian's maritime fleet, led by Marcus Agrippa, and the combined fleets of Mark Antony and Cleopatra. The battle took place on 2 September 31 BC in the Ionian Sea, near the former Roman colony of Actium, Greece, and was the climax of over a decade of rivalry between Octavian and Mark Antony.
9. Battle of the Teutoburg Forest9 CE
   The Battle of the Teutoburg Forest, also called the Varus Disaster or Varian Disaster by Roman historians, was a major battle fought between an alliance of Germanic peoples and the Roman Empire between 8 and 11 September 9 CE, possibly near modern Kalkriese. Fighting began with an ambush by the Germanic alliance on three Roman legions being led by Publius Quinctilius Varus and their auxiliaries; the alliance was led by Arminius, a Germanic chieftain and officer of Varus's auxilia. Arminius had received Roman citizenship and a Roman military education, thus allowing him to deceive the Romans methodically and anticipate their tactical responses.
10. Council of Jerusalem50 CE
    The Council of Jerusalem or Apostolic Council is a council described in chapter 15 of the Acts of the Apostles, held in Jerusalem c. AD 48–50.
11. First Jewish-Roman War66 CE
    The First Jewish–Roman War, also known as the War of Destruction, the Great Jewish Revolt, the First Jewish Revolt, or the Jewish War, was the first of three major Jewish rebellions against the Roman Empire. Fought in the province of Judaea, it resulted in the destruction of Jerusalem and the Jewish Temple, mass displacement, land appropriation, and the dissolution of the Jewish polity.
12. Bar Kokhba revolt132 CE
    The Bar Kokhba Revolt, also known as the Bar Kokhba War, the War of Betar, and the Third Jewish–Roman War, was the last and most devastating of three major Jewish rebellions against the Roman Empire. Led by Simon bar Kokhba, the rebels established an independent Jewish state that lasted over three years before being crushed by the Romans, leading to the near-total depopulation of Judea proper, along with mass killings, enslavement, and displacement.
