There were three leaders of the conspiracy: Marcus Junius Brutus, Gaius Cassius Longinus and Decimus Junius Brutus Albinus, otherwise known as Brutus, Cassius and that other Brutus everyone forgets about. Cicero wrote a letter to his best friend Atticus (it’s cute that they all have best friends) on 8 June 45 BCE – ten months before the murder – from Marcus Brutus’ holiday home in Antium and already the beginnings of a plot are obvious. Brutus was already concerned that he was unsafe and Cassius felt the same.
