Julius Caesar
Gaius Julius Caesar (12 July 100 BC – 15 March 44 BC), known by his nomen and cognomen Julius Caesar, was a populist Roman dictator, politician, and military general who played a critical role in the events that led to the demise of the Roman Republic and the rise of the Roman Empire.
He was also a historian and wrote Latin prose.
In 60 BC, Caesar, Crassus and Pompey formed the First Triumvirate, a political alliance that dominated Roman politics for several years.
Their attempts to amass power as "Populares" were opposed by the "Optimates" within the Roman Senate,
among them Cato the Younger with the frequent support of Cicero.
Caesar rose to become one of the most powerful politicians in the Roman Republic through a number of his accomplishments, notably his victories in the Gallic Wars, completed by 51 BC.
During this time, Caesar became the first Roman general to cross both the English Channel and the Rhine River, when he built a bridge across the Rhine and crossed the Channel to invade Britain.
Caesar's wars extended Rome's territory to Britain and past Gaul.
These achievements granted him unmatched military power and threatened to eclipse the standing of Pompey, who had realigned himself with the Senate after the death of Crassus in 53 BC.
With the Gallic Wars concluded, the Senate ordered Caesar to step down from his military command and return to Rome.
Leaving his command in Gaul meant losing his immunity from being charged as a criminal for waging unsanctioned wars.
As a result, Caesar found himself with no other options but to cross the Rubicon with the 13th Legion in 49 BC, leaving his province and illegally entering Roman Italy under arms.
This began Caesar's civil war, and his victory in the war by 45 BC put him in an unrivalled position of power and influence.
After assuming control of government, Caesar began a program of social and governmental reforms, including the creation of the Julian calendar.
He gave citizenship to many residents of far regions of the Roman Republic.
He initiated land reform and support for veterans.
He centralized the bureaucracy of the Republic and was eventually proclaimed "dictator for life" (Latin: dictator perpetuo), giving him additional authority.
His populist and authoritarian reforms angered the elites, who began to conspire against him.
On the Ides of March (15 March), 44 BC, Caesar was assassinated by a group of rebellious senators led by Gaius Cassius Longinus, Marcus Junius Brutus and Decimus Junius Brutus, who stabbed him to death.
A new series of civil wars broke out and the constitutional government of the Republic was never fully restored.
Caesar's adopted heir Octavian, later known as Augustus, rose to sole power after defeating his opponents in the civil war.
Octavian set about solidifying his power, and the era of the Roman Empire began.
Much of Caesar's life is known from his own accounts of his military campaigns and from other contemporary sources, mainly the letters and speeches of Cicero and the historical writings of Sallust.
The later biographies of Caesar by Suetonius and Plutarch are also major sources.
Caesar is considered by many historians to be one of the greatest military commanders in history.
His cognomen was subsequently adopted as a synonym for "Emperor"; the title "Caesar" was used throughout the Roman Empire, giving rise to modern cognates such as Kaiser and Tsar.
He has frequently appeared in literary and artistic works, and his political philosophy, known as Caesarism inspired politicians into the modern era.
