Publius Servilius Casca Longus (died c. 42 BC) was one of the assassins of Julius Caesar and plebeian tribune in 43 BC. He and several other senators conspired to kill him, a plan which they carried out on 15 March 44 BC. Afterward, Casca fought with the liberators during the Liberators' civil war. He is believed to have died at the Battle of Phillipi either by suicide or at the hands of Octavian's forces.[1]
