Overview

Publius Servilius Casca Longus (born 84 BC, died c. 42 BC) was a Roman politician and one of the conspirators who assassinated Gaius Julius Caesar on 15 March 44 BC, the Ides of March. Ancient biographers record Casca as one of the earliest attackers in the killing; he is commonly described as delivering a wound to Caesar's neck before other conspirators joined in.

Background and motives

Casca belonged to the gens Servilia, a long-standing Roman family. At the time of the plot against Caesar he reportedly held the office of tribune of the people (tribunus plebis), a position that had both political and symbolic weight in the late Republic. The conspirators' motives were mixed: some sought to preserve republican institutions, others to defend personal or class interests against Caesar's accumulation of authority. Ancient sources such as Plutarch and Suetonius discuss Casca alongside better-known figures, but they provide limited detail about his private life or precise motivations.

Role in the assassination

Contemporary accounts and later historians agree that Casca played an active and visible role in the attack carried out in the Theatre of Pompey on 15 March 44 BC. According to those narratives, Casca struck one of the first blows at Caesar's neck, an action that immediately transformed a political conspiracy into a public killing. His participation helped to galvanize the other senators involved in the plot. The event quickly polarized Rome, triggering both public outrage and praise depending on political allegiance.

Aftermath and final years

After the assassination, Casca fled the city along with other conspirators. He joined the forces led by Marcus Junius Brutus and Gaius Cassius Longinus in the ensuing civil conflict often called the Liberators' civil war. That conflict pitted the assassins and their supporters against the Second Triumvirate, composed of Octavian, Mark Antony and Lepidus, and their allies (the Second Triumvirate). Following the defeat of the republican forces at the battles of Philippi in 42 BC, Casca is reported to have taken his own life rather than be captured (accounts of his death place it in this period).

Coins, cultural memory and distinguishing facts

Casca's name survives on a small number of contemporary artifacts and in later literature. A coin associated with the assassins bears the names of Brutus and Casca together; next to Casca's name a bearded figure is sometimes interpreted as the sea god Neptune in numismatic studies (interpretations of the image). In literature and drama, Casca appears as a supporting figure—most famously in William Shakespeare's Julius Caesar—frequently portrayed as blunt and outspoken. Historians note that, despite his lesser fame compared with Brutus or Cassius, Casca's role as one of the first attackers makes him a pivotal actor in the events that ended the late Roman Republic.

Key points and timeline

  • 84 BC: traditional year of birth.
  • 44 BC, 15 March: took part in the assassination of Julius Caesar; recorded as one of the first to strike.
  • After March 44 BC: fled Rome and aligned with the conspirators' leaders.
  • c. 42 BC: died by suicide during the civil war following the assassination.

Because surviving sources for Casca are limited and often shaped by later political agendas, many details of his life remain sketchy. Modern scholars reconstruct his biography from fragmentary ancient texts, numismatic evidence and the broader political history of the late Republic.
